2L Hempy Coco Coir

[jandre2k3]

but won't the roots grow into the water at the bottom though? I mean I know in a 5 gallon DWC it reaches into the water, but there is a airstone to keep the water moving... sorry, just trying to get the whole picture and not bits and pieces,
If the roots grow throughout the whole 2 litter bottle in a normal hempy grow... doesn't that mean it would do the same with this??? therefore the roots would be sitting in the water all the time at that point... right???

Yes! That's exactly right.

It's only about 350mL-400mL or 0.35L-0.4L in the "Res" of that design of hempy, not a whole lot to displace there. Furthermore, once the roots grow in, there's even less. Sort of like a very small DWC in the bottom of it. The plant will get fresh O2 rich premix added to the reservoir when he waters. So no root rot either being replaced with fresh every other day. I would be inclined to water every day to be sure, but I'm sure he's tested this design on the current watering schedule and found it sufficient. Besides, when the plants get larger, they will take up all of that small amount within a day, maybe a day and a half, and the coco provides the final moisture to tide them over till he waters again.

The roots grow into the bottom and displace more of the water, and absorb the rest in a day, maybe a day and a half.

i get it now and its actually a great idea. would u use coco nutes or hydro?

 

[Twelve12]

I find in my experimental grow with the 2L DWC Hempy is that the plant grow vigorously and this is from the same watering habit/routine, that's every other day the plant gets a fresh feeding. The reservoir is small that it does not need air stone or anything to move the water. It takes about a week for water to go stale, however the plant will use it all up in few days - way before it would go stale, and for extra prevention I water till there is some runoff with a weekly flush.

The oxygen comes into the water from 3 sources; Cold water (holds more oxygen over warn/hot), water pulling oxygen down when feeding the plant from the top, also the hempy hole being high up allowing some air into the reservoir.

The roots will sit in the water and will constantly feed the plant. Slow feeding at night, fast feeding during the lights on. More roots bigger stock, higher yield, explosive growth = happy community.

This setup can work with perlite & vermiculite, coco, hydroton, rockwool, and not recommended for soil. Just like 5gal DWC bucket but shrink down to 1L worth of reservoir without air stone, and the added hempy hole 2in from the top.

The hempy hole allow the exchange of old premix with new without having to lift the top piece and dump the water out, this happen automatically as long as the water is replaced with new at least once a week (if it has not drank it all up) to keep the roots in good health. Remember, salt will built up so a weekly flush is recommended. Again, with the hempy hole no need to lift the top piece flushing makes it easy, keep a tray under to catch the runoff.

Nutrients is still the same 3-parts BPN!

I could let them sit on the tray and put some hydrotons over them. But keep in mind that this is a perpetual grow so we got flowering plants at different stages. Best to have each plants in their own unit. So if one plant have disease it does not affect the rest of the crop if the root systems are sharing the same reservoir. Also makes easy re/moving/adding in plants.

Already got 20x 2L DWC Hempy going...will do 40 more and leave the rest for comparison. I guess we'll have to see if my intuition is in tune...

Let me know if there is any questions. I'll do my best to explain them.

would I be able to use my Organics in this???

Twelve12 I like your attitude. Your perseverance to a concept. I like where you are going in your endeavors. March on...

I knew you guys would take the 2L idea and run with it. Very nice work here T.

That's the beauty of this system he's designed, tweaked, and shared here! Organics have microbes and enzymes for healthy root growth, but they do go stale after a while. This alone is by far the biggest reason I have found that most organic farmers shy away from hydroponics because of the instability in the nutrients that is caused by the system itself. Thus, the organic farmer is left with few options for substrate.

Enter the Twelve12 2L Coco Coir Hempy Pot System. With the constant replacement of new nutes every other day and a flush every week, the organic matter that would otherwise go bad and work against any other hydroponic system's delivery system and drain plumbing, this is not a worry. It hasn't the more intricate and complicated tubing to collect "bad bugs" in the various connections, that would destroy the otherwise perfect nutrition for the plants. To the contrary, it tends to lend itself to organics and actually work with the strength of the nutrients, and minimize the weaknesses/problems that other hydroponic systems present to the gardener. I dare say that it is perfect for organics.

I would only point out that for mothering it doesn't seem that it allows much room for an individual plant to fill out to gain the "bushy" stature that is preferred because they are packed tightly together to gain stability. So to have a wide selection for several "perfect" specimens for rooting for taking cuttings, one might need to find an alternate mothering system.

oh ah ok, a simple yes would have been fine... LOL just messing, thanks for the info there jandre.

So what you are saying is that I would want to keep my mother plants, vegging in a 5 gallon bucket, while I can do these as the flowering grow from the cuttings that I would take from the mothers... Right?

Just want to clear this up and make it easier for anyone else that might not understand, you know T12's journal gets a lot of noobs that would actually be more like on this... LOL, I get you though, as for I grow with Organics, as you know...

Now for my question to this... how about the time that the cuttings are first put into these, the roots have yet to go down into the res, so would the nute water be dumped for this amount of time til the roots get in there and start soaking it up?
And am I to understand that you would still put the nutrient water through the top (in the coco) correct?

 

[jandre2k3]

Preface: "noobs" in this case is not a derogatory term when used here, but rather refers to simply the inexperience of the new grower.

Noobs: I would suggest a cloner tray with humidity dome, unless you have some extra 2L Bottoms to place over the tops for the fresh cuttings with no roots. Also, in this case no nutes every other day until roots form, rather, a misting 2-3 times a day.

so would the nute water be dumped for this amount of time til the roots get in there and start soaking it up?

All: The weekly flush takes care of that.

And am I to understand that you would still put the nutrient water through the top (in the coco) correct?

Simply: Yup.

Astonr420 have not try it myself. This setup work best with chem nutes.

Thanks for the kind words SmokzAlot.

All thanks to you, 420fied.

Cultivator you can use any chemical nutes, not sure about coco nutes have not use them. I only use the 3-parts from Blue Planet Nutrients and works great.

Thanks Blue Planet Nutrients, SpiriTHC, jandre2k3, HighFlyin5

Cool idea, Twelve.

Reminds me a bit of how my Flo N Gro (Ebb N Grow style system) works. Periodic flood/drains, but there is always an inch or two in the bottom of the bucket (it's designed that way). Because there are multiple floods per day, it stays oxygenated -- no problem.

People who run systems like mine are often afraid of the water that gets left in the buckets, and insist on putting airstones in there or elevating the buckets to remove the water... But, it's a feature! And if for some reason things don't get watered on time, it can save your bacon. Your idea seems less Hempy/DWC, more Hempy/Ebb N Gro in that sense, as you are flooding the hempies and leaving a little passively oxygenated reservoir for them. Whatever you call it, good idea and +rep.

 

[Twelve12]

Astonr420 Now for my question to this... how about the time that the cuttings are first put into these, the roots have yet to go down into the res, so would the nute water be dumped for this amount of time til the roots get in there and start soaking it up?

I keep it simple and just water it normally. Roots will grow through the available holes (from the top piece) into the res in few days. Leave the water in there even if the root has not come through. With the hempy hole you're always safe from overflow, water as much as you like to and less frequent watering for soil.

And am I to understand that you would still put the nutrient water through the top (in the coco) correct?


Yes, feeding is always through the top. This saturate the medium and top roots at the same time lubricating the bottom roots as the water sliding down.

I think I posted this in another thread once.

I grew peppers with a flood and drain 2L bottle setup modified from hydroponicsonline dot com. Always wanted to try it with some weed, but haven't had a chance yet.

One year I flood and drained.
The next year I did a recirculating drip from the top.
Both were quite productive as you can see. Used Peters Professional and that's it.

The white tube on the right is the overflow tube that could be adjusted to any height you wanted if you wanted a hempy version. If I ever build another one, I will use some sort of inserts like a big gulp cup or something for easy removal and cleaning.

Well thanks for the idea for a test run. OH YEA!

Got it, thanks for clearing this all up brotha

 

[Twelve12]

Xlr8 thank you for the kind words. Very excited to see more plants in this new upgrade. You're right it can save my bacon when I missed watering, and often I do. Have not had a plant withered on me, yet, however good to know there is a small safety net.

Hash Hound I like that setup are you still running it?

Astonr420 you're welcome let me know when you get a prototype up and running. Interested to see how they perform.

For sure, your pretty good about being in my journal as well, so you'll know when I am going it!!! but I will give you a heads up also...

one last question, did you black out the bottom of these 2 litters as well??

 

[Twelve12]

Astonr420 one last question, did you black out the bottom of these 2 litters as well??

Yes and no. I reuse bottles and some are painted while the new ones are not. I don't paint them any more, no difference from my experience.

 

[Truth Seeker]

I didn't think with it being a DWC type of thing that it would matter... and you said that you keep them in a clear basket type deal??

 

[Twelve12]

Results from the Turbo Kloner T24. The clones been in there for a little over 2 weeks. Very nice root growth. I like the compact size of the kloner, leak free, and operate quietly.

Got 48x clones rooting every two weeks should be good to keep the perpetual going. I'll get another T24 soon for extras and pick the best clones to flower. Only have one CFL bulb (23w 5000K) over the clones, under GLR cycle.

Also in the process of adding more clone sites on my DIY aero cloner. Increase the current 24 to 38. These clones will go into the new 2L DWC Hempy.
