Grow Project(suggestions welcome:)

Im looking to build a grow room with an Ebb and Flow system and i was wondering if there a better hydro system for more than 15-20 plants??
What liquid nutes should i use?
What grow light should i be using?(low heat woudl be nice)

YouTube - Butterfly Aeroponics

I have one system for clones (2 weeks) under small 24" Fluorescent
i just move the whole lid to veg when roots show. No nutes only water.

I have another system for a quick veg under 250 watt MH.
After another two weeks I take cuttings from these plants and then move the plants to the flower room. 500-600ppm

8 systems are in my flower room under a 1000 watt warm MH for a 2 week harvest cycle. 1700-2900ppm

No mothers needed. Just take cuttings off of the veg plants before they go into flowering room.

ok ok but do you think 1 200 W red/blu bulb floro system will be enough for a 2' by 4' tray that is 1 ft or so away??

I personally use Gen Hydro nutes and their Vegan Compost Tea and Flora Nectar. Makes some tasty buds!
