approxamately how many plants can you grow under 1 hps/mh light?
A 400w HPS will cover an area of about 4 x 4 foot. So you should be good for anything between 6-9 plants under there depending on variety how tall they get how much side branching etc.400 watts. in soil. that help any?
You should be able to do 6 plants under a 400 yeah.so it could do 6 plants easy right?
