I'm on my first hydro endevor, 10 gal rez, 1 plant, DWC. Details here:

I have a couple of possibly useless comments to add! *grin*

On avoiding root tangle:

I was thinking that setting up a plastic divider might work... In my 4 plant system it would be like this: 2 large pieces of rigid plastic, each cut most of the way down the middle and stuck together to form an X. A bazillion tiny holes drilled in the plastic to allow for flow. An airstone in each section. Checking the roots daily and, with fingers wet with rez solution, tease away any from the holes. I think they still might try to work their way thru the holes though.

My other thought on this is cheesecloth. Make a little tubular tent around each pot with a few layers of cheesecloth, open at the bottom, airstone inside each tube. The roots very likely will get entangled in their own cheesecloth tube, but it would be tough for them to get thru it.

Probably ought to soak the cheesecloth in pH balanced H2O first - I'm not sure if it would effect the pH fresh.


On medicinal mj:

I have a bevy of back problems, and take morphine and oxy for pain. Indica-heavy strains work just as well, with benefits of being non-addictive & easier dose control. I pay little heed to seed bank's distinctions on what is medicinal and what is not - Ya use what works for you, and if it is lower THC, you can just use more and/or water cure it.

Happy bubbles to all!
