With the lights you have that would be the best possible lighting you could have so Go with ur instinct, just watch the heat.I was thinking of uusing the hps on top and 4 42watt cfls around the sides?
my plants about 16" tall and very bushy
y the cfl even 8 of them u still just got 2,800 lumens the hps will put out 15,000I WOULD USE BOTH OF THEM BUT IF I HAD TO CHOOSE IT WOULD BE cfl
