    Hi!

    Ive set up a deep water culture grow, and Im wondering if anyone has any experience with keeping the root systems suspended in a constant aerated solution? I tried looking for a previous post on this, but no one really has answered my specific questions below, so Ill post up and ask em.

    Heres where Im at now:

    I basically used a cheap $80 Aerogarden Herb machine as a test run growing bag seeds and miracle grow, and it was a smashing success! So after trolling this board for a few months and educating myself, I went out, got an armoire, gutted it, and built a grow cabinet, stealth style. This should be plenty I think, since Im just growing personal stash.

    I basicly copied the Aerograden principal, and tried to improve on it. I coated everything inside with mylar, installed 4 45w CFL in the upper chamber where I plan to grow mothers and use my old Aerogarden as a cloaner, and a 400w HPS lamp in the bottom chamber, setting over 2 Rubbermaid buckets with 6 net pots each in them, full of rockwool. I installed fresh air instake fans into both chambers, and have a cool tube built into the HPS down below. In the bottom chamber, I have 3' of clearance between the HPS and the tops of the resevoirs.

    I planned to have the roots in the solution full time, with double airstones in the resevoir to ensure lots of air, as well as having the rockwool constantly rain solution down into the resevoir itself, just like the Aerogarden setup.

    Heres my questions:

    1) Should I keep the water level all the way up to the rock wool? Or should I keep it lower, so that the roots suspend thru a few inches of air before tapping into the resevoir below?

    2) I plan on going SOG style into my 12 resevoir planters, mothers > clones > Flowering......and skip the veg stage entirely, to keep the plants short. Should I top them as well?

    3) I ordered a strain called "Supergirl", because the Nirvana ad said it was good for indoor hydro grows, hard to kill, and had big yields. Anyone have any suggestions with this strain, or have any experience with it?

    Thanks in advance!

    Definitly keep the water level below the net pots. Keep the water about an inch and a half below the bottom of the net pots.

    2) Plan on going SOG style into my 12 resevoir planters, mothers > clones > Flowering......and skip the veg stage entirely, to keep the plants short. Should I top them as well?

    That is up to you. I personally never cut the tops, only thing I do is thin some leaves every once in awhile..I believe, and my opinion only, that keeping the plant as natural as possible is truly best..(until my bud gets covered by a non essential (again my opinion) leaf.

    30 I ordered a strain called "Supergirl", because the Nirvana ad said it was good for indoor hydro grows, hard to kill, and had big yields. Anyone have any suggestions with this strain, or have any experience with it?

    I can honestly say I don't have a clue about this strain.

    wet rockwool will drown your plants... make sure it is only damp and never soaked... also do not crush it... put it in a salad spinner or use your arms to shake the water out... never crush it...

    are you using hydroton or anything? just straight rockwool?? be careful not to soak it...

    I do DWC and started with an AG as well... but I use foam....

    I work with clones, and I prefer the ones that have 2 branches...

    I LST the branches down and around the plant, exposing all budsites to the same light intensity...

    Best of luck...

    Yeah I was thinking of bending them gently to get more bud growth too.

    Thanks for the advice on the rockwool.
