Hi everyone. Being a new grower, I have decided to simplify my grow room, but still get good yields, growth rates, quality, etc. I was thinking of getting 2 3x3 trays, each with it's own res. Build and ebb/flow setup but without the timer. That way it's always flooded to the drain level. Then, taking a piece of home depot insulation Styrofoam (1 or 2". the pink stuff. real solid), build a raft with a variable number of holes for net pots.

Here is what I've got to work with: 6x3.75x9 room.
1 8000BTU A/c portable. will get 2 600w (air cooled?) lights HPS. This is a perpetual flower room. Cloning vegging elsewhere (4x2 grow tent). will add co2 when funds available. will mount the 2 tables on some sort of 2x4 table made DIY. May install a drop ceiling (to hang the lights/ use less co2/possible heat exhaust if its insulated).

The question is: any feedback on the system? Do you need any more info? should I go sog or scrog?

Thanks,
HT
