I am looking for a light system that will grow 6 to 8 plants. I have come across this new 1000w digital ballast (Quantum 1000 watt Dimmable Electronic switchable Ballast) but would like some advise on a reflector or hood that I should get to go along with it. Also,,,is this 1000w light a good choice?? Or should I get 2 600w balasts which are not as efficient as the dimmable and add 1 or 2 plants to the mix? Advise would be greatly appreciated. Im rackn my brain trying to figure out a lighting system.
