right system for max growth
 

hi, im using your 11 bottle system. my question is about lights i have about 12 sq ft.i have the tub shower grow room. you said 400 hps will do fine but will i get better results using a 1000 hps.or how about two 400 systems one mh one hps. or two 1000 watt systems. can you run mh and hps at same time. I haven't bought lights yet i want to make sure i get the right system for max growth and so i don't have to up grade later.

two 400 W. (one of each) is better than one 1000 W because the plants get light from two points instead of one.
By using both MH and HPS you can make sure you give your plants the full spectrum of light needed for maximum growth.
