Hydroponics is a well-known technique for cultivating soilless indoors, this technique consists of soaking the roots in a nutrient solution and lots of oxygen. Using this method means that there is no soil and plants grow in a sterile, inert growing medium. The hydroponic method provides the nutrients, water, and oxygen directly to the roots. As there is no need for massive roots or extra energy to absorb the nutrients, the plants grow much faster and bigger, here’s a hydroponic grow guide and some tips to help you decide on the best way to grow autoflowers hydroponically in your growing space.

1. What are pH and PPM Levels?

Before talking about the different hydroponic setups we must advise that in hydroponic grow is essential to measure pH and PPM levels every day. We use the pH meter to know how alkaline or acidic our solution is and the EC meter is used to measure PPM levels (PPM means particles per million).

A simple way to understand it is we measure pH levels to be sure our plant’s nutrient intake is optimal. We measure PPM levels to make sure we are giving the right amount of nutrients to our plant and to ensure our plant is absorbing nutrients.

2. Measuring and Adjusting pH and EC Levels

In hydroponics, it’s essential to measure pH and PPM levels every day, preferably every time we feed our autoflowers. You should measure runoff and the solution going in, and compare. PH levels should be around 5.5-5.8. If they are too high or too low your plant will have problems absorbing nutrients. You can use a pH-adjusting solution (pH up or pH down) and measure again until it’s as close as possible to the desired amount. PPM levels go up for each stage so here’s a table to better visualize them:

Keep in mind, if PPM levels are too low or too high, your autoflower will show symptoms of under or overfeeding.

3. Hydroponic Setups

No matter which hydroponic system you choose you’ll need:

  • a water pump;
  • an air stone;
  • a timer;
  • a reservoir;

Make sure that you pick a large enough reservoir so it can hold enough water and nutrients for a couple of weeks. The reservoir has to have a lid so your solution doesn’t evaporate. You’ll need another reservoir to hold water where you can test and adjust pH. We recommend having a third one in case one of the other two breaks. The reservoir containing the nutrient solution should be insulated so you can control the temperature. Now, have in mind that there’s no such thing as the best hydroponic system for cannabis because the best one for you will depend on what suits you better and what you can afford.

Hydro Setups: Ebb and flow & Continuous Flow

This hydroponic system is quite simple and it’s the most popular choice within growers because it doesn’t require too much work, it’s low maintenance, and very productive. This system is ideal for beginners. Ebb and flow works by placing our reservoir under the growing bed. The water pump turns on to fill the growing bed (where the plants are) every 15 min with our solution. When it reaches its higher level, the pump turns off and the solution is then drained through a pipe. In this setup, you can use coco fiber, perlite, or clay pebbles to support your plant. Growing hydroponically you need some kind of medium so the roots can hold themselves onto something.

The hydroponic setup for Ebb and flow/Continuous Flow is basically the same with minor changes in the size and height of the drain pipes.

With basically the same setup as the Ebb and flow, the Continuous flow technique is the opposite. This method consists of providing a continuous flow of solution. The never-ending stream of water flows around the roots, allowing them to absorb what they need from it. As opposed to the Ebb and flow which fills all the way to the limit and then drains all at once.

Pros Cons
Easy to build Problems with breakdowns
Nutrient abundance Unstable pH
Low cost Can result in nutrient deficiencies

Hydro Setups: Deep water culture (DWC)

Deep water culture is a style of hydroponic growing that may or may not use a medium like perlite, coco, or clay pebbles. In a DWC setup, you have a reservoir filled with a mix of water and nutrients, the lid holds special pots or nets with their roots stretching down having part of them submerged in the solution, this way they have nutrients available all day long and can absorb nutrients when they want to.

As we know, oxygen is essential for plants, so you need to use an air stone in this setup to keep the solution oxygenated.

Pros Cons
Faster growth Completely depends on the air pump
Little maintenance Hard to maintain water temperature
No need for a lot of equipment PH may fluctuate a lot in smaller setups

Hydro Setups: Shallow water culture (SWC)

Shallow water cultures (SWC) is basically the same as deep water culture (DWC) but instead of growing in a bucket or big container, this system consists of a wide reservoir that’s no deeper than 20 – 25 cm, where plants get a constant flow of nutrient solution. SWC is considered more efficient in terms of space, however, it’s usually only used for clones because it’s super hard to maintain correct pH levels due to the nutrient solution and water in the reservoir needing to be monitored constantly.

As you may know, oxygenation is vital when growing in hydro so make sure the water is flowing properly or add air stones for the water to be properly oxygenated.

Pros Cons
Water flow provides enough oxygenation Needs constant monitoring
Bigger yields Works better when growing smaller plants
Uses less water and nutrients PH can fluctuate a lot
Deep Water Culture (DWC) vs Shallow Water Culture (SWC)

As mentioned, SWC is basically the same as DWC but instead of growing in a deep reservoir, you grow in a wide one so a shallow water culture setup may be more suited for growers with limited vertical space but plenty of horizontal space. Another important difference is that an SWC setup uses less water which allows you to save on water and nutrients but, due to using less water, pH levels can oscillate and the temperature of the water may fluctuate; This means that despite saving money, an SWC requires you to be precise and needs constant monitoring so it’s recommended for more experienced growers.

Hydro Setups: Nutrient Film Technique

The nutrient film technique consists of exposing the roots to the air permanently and keeping a thin flow of water along the bottom in which the tips of the roots are soaked, providing the nutrients they need while the rest of the roots are exposed to oxygen.

After years of utilizing this technique, growers realized the downsides to this technique which were quite bad, some growers quickly ran into problems such as root rot so they upgraded the nutrient film technique in a form where the roots are suspended in net pots which ended up being very similar to the Ebb and flow method but with thin layer of water constantly flowing underneath the roots.

Pros Cons
Easy to inspect roots for diseases Cannot stop the water flow
Less water and nutrient consumption Water can heat up faster than in other setups
Prevents nutrient build-up Must check regularly

Hydro setups: Aeroponics

Aeroponics is a technique very similar to the DWC technique mentioned previously. The setup is the same, a reservoir filled with a solution of water and nutrients. The difference is, instead of submerging the roots, we leave them hanging in midair, using a sprinkler to mist water directly on the roots every 3-5 min.

With aeroponics method the roots are hanging in midair and watered directly with a sprinkler every 3-5 min.

The reservoir must be lightproof and waterproof which helps create a highly humid environment. There’s no need to use an air stone as the roots are literally surrounded by oxygen.

Pros Cons
Maximum nutrient absorption Requires constant attention
Easier to move plants around Initial cost can be high
Healthier plants Requires a bit of technical knowledge

Hydro setups: Drip Irrigation and Continuous Drip Irrigation

The Drip irrigation method consists of having a large reservoir with tubes that is reaching each pot individually. On the tip of the tubes, there are drippers that are placed above the grow medium (this method can be used with hydroponic mediums or soil). You have to program a timer that controls the amount of solution and frequency your plants get fed. When the timer turns on, a water pump is activated, watering your plant for the exact amount of time you programmed, not a drop more, not a drop less. Normally they are watered in increments of 15 mins and for a duration of around 4 min. You don’t even have to be there to feed them. Ideally, you would be just checking if the system is working properly and that’s it.

This is a perfect option for beginners. Except checking on the system once in a while it doesn’t require much hands-on action.

There is an adaptation of the drip irrigation technique called Continuous drip irrigation. It uses the same setup but instead of watering when the timer turns on, the water pump never turns off, providing a continuous flow of solution for the plant. Like in the DWC technique, this way the plants can be fed whenever they need to and will result in faster growth and much bigger plants.

Pros Cons
Minimizer evaporation thus saving water Must be controlled closely
Healthy soil due to optimal waterings Tubing might get clogged
Little runoff results in a richer soil Equipment must be on 24/7

Hydro setups: Wick System

A wick system (aka wicking) is another method used to grow cannabis hydroponically but unlike the other methods cited before, this one is relatively low-maintenance, easy to use, and can be done for cheap so it’s recommended for growers that want to start growing hydroponically but want to start with a simple setup.

A wick system is the cheapest hydro system but it could be easier to get root rot so you have to be extremely careful.

This system basically consists of using the principle of capillary action to provide water to your plants so as your plants draw nutrients to the roots, the wick pulls the nutrient solution from the reservoir, basically watering the soil.

Pros Cons
Simple and accessible for beginners Not suitable for big plants
Minimal maintenance Not very efficient at delivering nutrients
Uses less electricity than other hydro setups Easier to get nutrient build-up in the soil

This is a huge benefit because it makes it almost impossible to overwater your marijuana plants, although due to the wicks being always moist, it’s possible to get root rot so it’s essential to maintain good growing conditions.

4. Best Autoflowers To Grow In A Hydro Setup

Growing hydroponically consists of feeding your plant and maintaining good conditions for the roots to grow in, just like when growing in coco or soil so any strain will do exceptionally well in a hydro setup.

Orange Sherbet Auto

If you have enough space in your grow room try cultivating one of the big yielders like our Orange Sherbet Auto. Hydroponic setup will let her fully develop resulting in a huge yield.

I grew this with other fast buds strains. I’m very happy how they all grew. I use soil, 19L pots on a 20/4 light cycle. They love it.

Growing this strain in a hydroponic setup will let her fully develop, growing up to 150cm and producing huge yields.

Grow tips
  • We recommend LST to open up the canopy and allow light to reach the lower flowering sites, increasing yields even further.
  • It’s most likely that you’ll need to provide support to the branches due to the heavy buds so make sure you keep an eye out to prevent the branches from snapping.

Wedding Cheesecake Auto

Another great strain to grow hydroponically is our Wedding Cheesecake Auto which grows up to 130cm with several side branches, just like the Orange Sherbet Auto

Beautiful plants, and consistent among the three. I topped all of them and got around 115g off each in 2 gallon pots. Very pleased

By maintaining good growing conditions throughout the whole grow cycle you can expect huge yields of up to 600gr/m2 so it’s definitely a must for hydro growers.

Grow tips
  • This strain responds very well to LST so we recommend tying down the branches early in the vegetative stage to allow the buds to develop to the maximum.
  • We recommend using bigger pots (11-12L) to allow your plant to develop to the fullest and allow your plant to show its full potential.

5. Most Common Mistakes When Growing Hydroponically

Even though you might get excited to get better yields and bigger plants, growing in a hydro setup is not super easy and it has a learning curve to be able to do it properly and successfully so here are the main mistakes that will bring problems into your cannabis garden.

Ignoring pH Levels

The pH level is vital for your plants to be able to absorb nutrients properly, if the pH level oscillates your plants will have a hard time absorbing nutrients, showing signs of deficiencies and ultimately dying.

So to avoid this you will need to measure the pH at least once a day and with a good pH meter, remember that your plants grow thanks to the nutrient solution that feeds them so if the nutrient solution is off, your plants might not grow.

Using improper nutrients

Using improper nutrients will not only prevent your plants from growing to their fullest but can also end up clogging your hydro setup because some fertilizers may not dilute entirely and can end up clogging tubes and drains so make sure you use the best hydro fertilizers you can.

Incorrect lighting

Another super important factor is the light fixture, using the wrong kind of lighting or using a light that it’s not strong enough won’t allow your plants to perform photosynthesis properly and your plants won’t grow as strong and big as you would want to.

Now, there’s a lot of debate about which ones are better, LEDs or light bulbs but the truth is that you can get really good results with both, it’s just a matter of knowing how to use them but LEDs are usually preferred by growers due to their full-spectrum.

Not cleaning properly

It’s essential you clean your setup before using it and after every grow cycle because the nutrient solution can end up getting harmful bacteria or you can end up with a hydro setup full of algae so you should clean not only your equipment but the entire grow space your plants are in.

6. Not Ready for a Full Hydro Setup, But Want to Dip Your Toes Into the Hydro World?

Let’s talk coco coir! Ok, so now we have been through the whole process of setting up all the different types of pure hydroponic options. And while all of them will produce fantastic results, they are pretty complicated processes that take a fair bit of effort and funds to set up, and once the setup is done the work is far from over. Hydro setups need constant attention, far more than soil grows for sure. But, is there another option? One that offers some of the ease of soil growing mixed with the obvious yield advantages that a hydro setup offers? Yes indeed! Say hello to coco-coir.

But what exactly is coco-coir, and how can we use it to grow pot?

Well, to put it simply, coco-coir is the perfect mix of both hydroponics and soil. It offers most of the advantages of both styles of cultivation with almost none of the drawbacks. It is budget-friendly, easy to work with, and offers fantastic growth potential. Coco-coir is a totally inert hydroponic medium that is made from the shaggy outer layer that covers a coconut. Do you know the stringy, almost hair-like shag that you get on a coconut? That’s the stuff. But don’t go out and start buying up all the coconuts you can lay your hands on just yet.

Since it is a totally inert medium you need to add all the nutrients just as you would with a pure hydro setup. But, unlike pure hydroponics, where the roots are suspended in the nutrient solution, the roots are held in the coco-coir which acts in a very similar way to soil. This means the roots are far more protected from not only pests, fungi, and disease infestations but also to sunlight.

Ok, but what are the actual advantages of growing in coco-coir over hydro or soil?

We have briefly touched on some of the reasons why we love using coco as our growing medium, but let’s break it down:

  • Coco-coir offers Huge harvest potential and increases the speed of the lifecycle – Plants grown in coco-coir propagate almost as quickly as with pure hydro.
  • It offers amazing root zone oxygenation – some studies show that coco-coir holds up to 70% more oxygen in the root zone than pure soil. Root zone oxygenation plays a vital role in the speed of growth, the final yield, and potency.
  • It is highly resistant to pests, fungal, and disease infestations – The natural resistance is a huge plus for both indoor and outdoor cultivators.
  • It is renewable and environmentally friendly – Once reserved for the trash heap, these days coco-coir is being repurposed and can helo cultivators reduce their carbon footprint.
  • It requires less water and nutrient usage than soil – Coco-coir receives and drains much easier than pure soil, meaning the watering requirements of coco-coir are much lower.

These days, every single nutrient supplier has a dedicated range of nutrients to use for coco. They can be applied in pretty much any way you see fit, but the most common applications are either hand watering or drip-feeding. If you go down the hand watering route (which most beginner cultivators do), remember to always fully douse the coco-coir until you see about 30% of the nutrient solution runoff. Remember to also regularly check the pH of this runoff to ensure the substrate is in good shape and the root zone is in the right pH range for the nutrients to be available. It’s no good to feed perfectly pH’d water or nutrient solution if the substrate is at the wrong pH.

Are there any obvious drawbacks of using coco as the main medium choice?

As with any cultivating choice, there is a balance of advantages and disadvantages that you need to take into account before you decide on which route to go down. The cons of coco-coir are :

  • More work overall than using a soil-based substrate – While you can run an organic protocol with coco-coir, it is more complicated than using a good soil mix. Having to feed the plant with a nutrient solution is inherently more work than letting the plants feed naturally from soil.
  • Nutrient and pH issues are more common than soil cultivation – Plants in coco-coir are more sensitive to changes in the nutrient solution and pH, but thankfully they are also easier to fix thanks to the ease of flushing with coco-coir.
  • The terpene profile may not stack up against organic buds – Weed grown in coco will be strong as hell and taste amazing, but most cultivators agree that to get the absolute best terpene profile you need to use organic options.

7. In Conclusion

There’s no such thing as the best hydroponics system for cannabis, all autoflowers grown in hydroponic setups can grow much taller and quicker due to the constant feeding of nutrients and water as long as you do it properly. They can develop faster and produce frostier buds with more terpenes than plants growing in normal soil, resulting in overall better quality.

We highly recommend considering these techniques and we promise the end result (if done correctly) can be infinitely better than any plant grown in soil.

How to Grow Cannabis Seeds Hydroponically

How To Grow Cannabis Seeds Hydroponically – Hydroponic cultivation is a promising solution to many challenges of crop production. It fixes the need for arable land, deforestation, ecosystem degradation, climate changes, and other issues related to cannabis cultivation. For decades, hydroponics has proven its effectiveness in various settings, and cannabis farming is no exception.

What Is Hydroponic Cultivation?

Hydroponics is a method of cultivating plants without soil by using mineral nutrient solutions in an aqueous solvent. In hydroponic cannabis cultivation, farmers plant their seeds in inert growing media and then supply them with nutrient-rich solutions like oxygen and water. To ensure that the plants remain healthy, farmers must control the whole environment, including nutrition, lighting, temperature, humidity, and oxygen. This system encourages rapid growth, high yields, and top-quality cannabis.

How to Grow Cannabis Seeds Hydroponically

To achieve successful results in hydroponic farming, cannabis growers must become acquainted with every component that ensures a smooth and efficient hydroponic grow. This includes selecting a grow medium, hydroponic system, lighting, nutrients, and more.

Choosing a Hydroponic Growing Medium

The first step to growing cannabis seeds hydroponically is to choose a growing medium. The medium allows roots to access nutrients in the water easily. There is an array of growing media to consider, but the right medium depends on which hydroponic system you will be using. Some of the most popular media include:

Clay pebbles

Clay pebbles, also known as hydroton, are great at aerating cannabis root zones. These particles have large pore spaces, allowing the nutrient solutions to flow through the medium easily. Their large pore size also reduces the chance of blockages within the hydroponic system. Clay pebbles are set up by simply placing them in the container and creating gaps for easy root penetration into the water.

Clay pebbles are a popular choice for small-scale growers; however, this type of medium might be too costly for larger operations. Another drawback is that farmers sometimes need to adjust the pH of the medium to provide an optimal growing environment.

Rockwool

Made using basalt rock and recycled slag, Rockwool is a type of mineral wool that is a popular medium for cannabis cultivation. Rockwool is excellent for water retention, allowing for adequate hydration of the upper root system. This medium also provides exceptional drainage, preventing the plants from becoming overwatered. Although Rockwool is a popular medium that offers many benefits, it is not environmentally friendly and requires pH adjustment for optimal plant growth.

Perlite

Perlite is a volcanic glass that expands when exposed to high temperatures. This medium is affordable and easy to use, making it a popular choice for hydroponic and soil growers alike. Perlite provides adequate aeration and prevents compaction in garden soil as well as hydroponics.

This medium does not degrade or decompose and can be reused multiple times before it starts to break into smaller pebbles. Perlite has a neutral pH and will take on the pH of the nutrient solution it is submerged in, making it easy for growers to regulate the acidity or alkalinity of their media.

Coco Coir

Coco coir is made from the hairy fiber on the outer shell of coconuts. This type of medium allows for proper aeration and moisture retention in hydroponic systems. It also protects roots from the harsh effects of plant-stimulating hormones. Coco coir is environmentally friendly, has a neutral pH, is reusable, and does not allow for the growth of fungi.

Choosing a Hydroponic Growing System

Most hydroponic systems are similar in their use of nutrient-rich water solutions; however, they differ depending on the material used, setup, water exposure, and circulation. Still, farmers can go for DIY systems using buckets, pumps, drills, and air stones. The best hydroponic systems to consider are:

See also  Weed And Seed

Deep Water Culture (DWC)

Deepwater culture is a cheap and easy way for beginners to grow cannabis seeds hydroponically. To set up a DWC system, growers simply place their plants in buckets filled with nutrient-rich solutions and use air pumps to supply oxygen to the roots.

Because this system does not use a growing medium, it prevents pests from proliferating around the root zone. DWC systems are fully automated and require little maintenance to use, making them ideal for inexperienced growers or those with large-scale operations.

Ebb and Flow

This system consists of buckets hung over a growing tray with inlet and outlet waterways, both of which connect to an external tank. The tank periodically supplies the plants with fresh water that is rich in nutrients and oxygen. The system has a water pump and a timer to control the water cycle to and from the external tank and growing tray. Ebb and flow systems are ideal for beginners as these systems are highly effective, easy to use, and require minimal maintenance.

Nutrient Film Technique (NFT)

With the nutrient film technique, plants absorb nutrients and oxygen from a solution that flows through growing trays. The tube that circulates the solution is tilted slightly to allow the water to flow from one side of the reservoir to the other. With this system, crops receive a constant flow of nutrients and oxygen. Growers can conserve water and nutrients by using the nutrient film technique because the nutrient solution is constantly being recirculated.

Drip System

A drip system is a type of irrigation method that slowly drips nutrients and water into the roots of the cannabis plants. This system consists of a large tray with a growing medium such as clay pebbles or perlite. Cannabis plants access the constantly flowing solution through individual pipes, and the excess solution drips down the growing medium and back into the reservoir. Because drip systems slowly release water to the plants, it reduces the amount of water lost due to evaporation. This system is also very energy efficient, as it does not require a great deal of pressure from a powerful pump.

Wick System

Much like drip systems, wick systems use growing trays that are filled with clay pebbles. A water tank rests underneath the tray from which several wicks connect to the medium. The solution travels down the wicks, passively hydrating the roots of the plants. This type of system is entirely passive and does not require any pumps or air stones. Wick systems allow the plants to access only as much water as they need, meaning that growers need not worry about overwatering their crops.

Aeroponics

In aeroponic systems, plants are suspended inside of a chamber, and their roots are misted with water. Aeroponic systems are often used to start clones but can also be used throughout the entire growth cycle. This type of system may not be ideal for inexperienced growers, as it takes some expertise to set up and maintain. This system also makes it easy for pests and diseases to take hold in the garden.

Choosing Lighting

In the past, most farmers preferred to use high-intensity discharge lights (HIDs) such as high-pressure sodium (HPS) or metal halide (MH) lights. But the recent full spectrum light-emitting diode (LED) grow lights have had tremendous success.

MH lights are close to natural lighting and are abundant in blue and green spectrums, which are best for vegetative growth. HPS offers orange, amber, and red-light spectrums, which are best for later cannabis flowering stages. Farmers often use metal halide lights during the vegetative growth period and switch to high-pressure sodium lights during the flowering period.

Although HID lamps provide an excellent light source for plant growth, they waste lots of energy and produce excessive heat. To mitigate the heat, farmers should invest in robust ventilation systems, including can fans and oscillating fans.

Lately, many growers have started using full-spectrum LED lights, which are far more energy-efficient than HID ones. Moreover, they are perfect for all growing phases and don’t require a ballast to power them.

Because most strains of cannabis are photoperiod-dependent, farmers should carefully regulate the light cycle during the vegetative and flowering stages. This is a crucial step in growing cannabis seeds hydroponically.

Nutrients

Like other crops, cannabis requires an abundance of major nutrients, including nitrogen, phosphorus, and potassium. Additionally, it requires smaller amounts of other nutrients such as boron, sulfur, calcium, magnesium. The best way to feed cannabis plants is to use hydroponic nutrient solutions containing all the required nutrients for the vegetation and flowering periods.

2 thoughts on “ How to Grow Cannabis Seeds Hydroponically ”

I use general hydro nutrients and have found that because the ppm of my water is below 50 I have to add small amounts of vsma and so to get the best results in my deep water system. A ppm meter is very important to a hydro system.

Growing Hydroponic Feminized Cannabis Seeds

Growing hydroponic feminized seeds can produce amazing results for cannabis growers. Hydroponics growing methods can produce super fast growth rates, high yields and super clean potent buds. Cannabis thrives in hydroponics, where roots have more access to oxygen, water and nutrients round the clock versus conventional growing methods. A lot of bud farmers greatly reduce veg times by growing in hydroponics; still harvesting very large budded plants for the same flowering times; hydroponics can hypercharge your crops.

Just like there are a lot of great female seed strains to choose from, there are a lot of different types of hydroponic growing methods and systems that you can use. Fact is some are better suited to growing feminized seed strains than others–that’s because female seed plants develop a solid tap root; something cloned plants never have.

Restricting the tap root of a female cannabis seed strain puts a lot of stress on the genetics–just like with conventional feminized seed growing tips HERE. It’s best to avoid putting hard stresses on ANY feminized seed plant, or growers may trigger undesirable traits, including pollination in severe instances.

What are the Best Hydroponic Systems for Growing Female Seeds?

Typically hydro set ups with more space for the root system is best–DWC (deep water culture), RDWC (recirculating deep water culture), large coco pots and similar are ideal. These types of systems have plenty of room for tap roots to stretch out and support large healthy root systems. They are also very productive and save on water and labor.

What are Hydroponic Systems to Avoid to Grow Female Cannabis Seeds?

Smaller sized grow blocks, like rockwool or small pots filled with grow rocks, etc will restrict root development, creating stress on feminized cannabis seed genetics. A 6 inch cube or pot should be considered the bare minimum, provided that plants will be flowered not long after seedlings are established. Larger is recommended.

What are Other Important Things to Avoid with Hydroponic Female Seed Plants?

Avoid wide drifts or big ups and downs with EC/TDS, pH and temperature in the root zone or nutrient solution. In bigger water culture set ups or hydro systems growers may use reservoir chillers during hotter times or may require submersible aquarium type heaters during cooler months. Try and keep roots at a steady 65 to 75 deg F. Wide or frequent swings can put a lot of stress on certain strains and cannabis varieties, with some being more root sensitive than others.
