Hello all. This is my 1st post though I have been reading for the last few months and I must say it is very informative. I have a few questions that I am hoping to get some help with.

I will explain the set up I have followed by the questions:
I have a 4x8 hydrohut deluxe with 2 600w HPS, a goblin filter,630 cfm squirrel cage fan, 2 3x3 flood tables,and 2 smaller circulating fans.

Now for the questions.
I will be growing using the SOG and would like to use rockwool.Should I use the 4x4 or the 6x6 and should I line them side by side as many can fit? I figured side by side would be somewhere around 40 plants per tray.How often should I water 15 min 4x a day? Do I need to bring fresh air into the tent?Will humidity be a issue? I am about 95% I will add CO2 should I hang it from the ceiling and let it shhot down?Last is there any idea what my yield would be with this setup per tray? I am thinking I will start 1 3x3 tray and wait 30 days then start the other so I may harvest every month.

Any replies will be greatly appreciated.

Sounds like a good set up.

Now for the questions.

If you use 4x4 you will be able to put more plants in the flood table.

I'm a bit stoned so forgive the spelling errors.

one 3x3 flood tabe: using 4x4" rwc will give you around (3'x12"=36"/4"=9) so 9x9=81 plants side by side. using 6x6" rwc will give you around (36"/6"=6)(6x6=36 side by side)

You will want fresh air.

If you are at 95% hum now with out Co2 you need to get the number alot lower. I think it should be at 90% with co2. and 60 with out.

As for the Co2 I'm sure that it rises so you will want to use a tubing system that is placed into the plants or around them.

As for the big "Y" lets say you will do the LP (lollypop) using the 4x4 rwc and growing all 81 plants or so.

Lets say you get 7.13g per plant x 81 plants= 577.53g = 20.26 oz
now lets say you get 14.26 per plant x 81 plants= 1155.06g= 40.53 oz

36 x 7.13g per plant=256g=8.98oz
36 x 14.26=513.36g=18.01 oz
