im thinking of getting 1000w lights and i read they have to be 4-5 feet above the plants is this true? im gonna get a metal halide light for veg growth then a HPS for flowering
How many plants do you plan on growing? Each grow space is different. I always use the back of the hand test to determine the optimal distance. 4' to 5' seems a little far to me. It's probably more like 2'-3'. Good luck.
Dont forget floros for veg, and most people try and keep there hid at minimum 1 foot away from their plants.
