Join the 2L DWC-H Experiment

2L = 2L Soda Bottle
DWC = Deep Water Culture
H = Hempy

The 2L DWC-H setup has evolved in my grow room during the time I was running the 2L SOG (inspired by 420fied) back in Feb 2012. At the time I had some plants 1/2 way through and had to shut down the operation in haste (long story). I could not gather the final data to see if this setup is worth keeping.

This is where I need your help. If you have extra space in your flowering room, give a 2L DWC-H a try to see how effective it is.

Illustrations on how they come together.

Items needed:
- 1L or 2L bottle
- Scissors
- A drill for making holes. If you don't have a drill then a stake knife or a nail will do (heat up the knife/nail).
- Grow medium; works best with Perlite & Vermiculite, Coco Coir. Not sure about hydroton or soil. Feel free to test them out.

Steps:
•Take the bottle and cut in 1/3 off the top (5in down from the cap). You'll be using both pieces. The top to hold the plant above the reservoir, and the bottom is the reservoir.
• Put holes all around the top piece with a hot knife or nail for roots to grow into the reservoir. Remember to save the cap, add some holes in it too.
• Sit the top piece inside the bottom piece upside down like a cone. No need to secure it the weight of the medium & plant will push it down with the help from gravity.
• Make a hole for hempy on the bottom piece (3-4in down from the top). This acts as a "flood control" device, like those in hempy. I wanted the hole to be high enough so the reservoir holds more water, and low enough that the water line does not touch the top piece, to prevent flood and over watering.


At minimal your clone should be cut at 5-6in and root for 2 weeks to allow abundance root mass to develop before going into the 2L DWC-H. The grow medium I've used was 100% coco coir, but you can use anything that suits you.

This is what it looks like.

Best to place these in a tray to catch the run offs. Try not to lift the top piece too often it can dry out the roots. Flush/feed accordingly.

Become the pioneer in this growing method! To sign up let me know what grow medium you will be using and the strain you'll be growing along with a link to your journal, and you're all set. The adventure awaits.

Question/concern? Post them on this blog.

Thank you testers. It really means great deal to me that you guys are putting time and effort in testing this grow method out on my behalf. May the Bud God provide you with high yield, potency, and density. :love:

teSmp what grow medium will you be using? I'll add you to the list. Thanks for giving it a try! Comparison grow with the DWC will be great.

teSmp cool, P&V it is. Yes, mix it with some vermiculite will help retain moisture for the upper roots.

Count me in, as soon as my plants get to where I can clone. Coco Coir & BPN.

How do you think this way would be on transplanting from soil to the 2L?

Astonr420 awesome the general is here! Looking forward to it! I'm very excited to see how it will work with soil and organic mix!

Me to brotha, so excited to see this, I think that I am the only one that is also doing this 12/12 from seed. You have shown clones...

another test of the tests...

:peace2:

seagem Awesome! Added you to the list. Welcome to the experiment. If you are transplanting plant from soil best to rinse/take off the excess soil before placing in the coco coir. Do it gently and quickly to prevent too much shock.

SurfBuddy great! You're off to an adventure. Those younglings look cute. We will be watching.

Astonr420 Looking forward to it. Woohoo!

Ps there a link you can post form any of our sponsor's on the coco coir?

seagem honestly I do not know any sponsor that is selling coco coir. Have you look into your local hydroponic shop? They should carry some. Get the 5kg block from botanicare, it is so inexpensive and high quality coco coir.

ilikebike are you able to get a clone in the 2L DWC-H from your existing vegetative plant? You can still grow tomato in this setup, unfortunately only cannabis grower in this setup gets included in the list. I have no doubt that it will work just want to know how well it works (yield & potency wise). Hope you understand.

Here's pics of the 2L I made... I didn't have any paint so i wrapped it in aluminum foil tape. Maybe it will help keep the res. cool maybe not. Still will help keep some light out.

I'm going to try and clean the holes up a bit more.

teSmp I love how everyone has their own take on design and still keeping the basic components in place. Yours look like NASA helped you with it. Space age. It's going to be great! Looking good!

ilikebike thank you brother. How far did you make the hempy hole? I just added you to the list.

JuicySoil Great idea brother! I'll include this in the guide. With the drill bit we can control the hole size. You're right it help speeds up the DIY project greatly. Thanks for bringing this up.
