so i just picked up a 150watt hps to flower a single plant and jw what other peoples results are using only a 150watter? how close do u put these? im also using a 125watt cfl totaling about 21k lumens for a single large plant in a box 2.5ft x 4ft x 5.5ft tall right now the hps is about 10in from the scrog canopy temps are about 75 - low 80s in the box
I had a 150w when I first started, mine has the built in ballast and puts out a decent amount of heat, I used to keep it about 18-20" above the plants.
i grew 4 og's under a 150 watt hps. got 46 grams dry. keep the lights as close as u can without burning the leaves. i keep mine 12 inches away. anymore then that and i start seeing lots of stretching
nice... the tops to my plant fill out about a 2'x2' area and i actually measured the distance from the light which is about 9". i have a big box fan blowing upward through the canopy/screen and temps stay between 75-85 depending on outside temps. its looking like they are loving it also =]
