150 watt Question.

wuts up roll it up fam, i just got 2 150 hps. and i wanna know how close they should be from foilage. plus rep for a quick response im bout to go set them up now. also , right now i got 3 lemon haze a 1 thai skunk in flower, i think im just gonna keep adding more 150s instead of getting a 400 watt. but with these 2 how many plants do yall think i can flower. im not gonna let them get over 4 feet. the lemons will prob only get to 3 feet cause i started flower when they were barely a foot

i got a 150 and i got it about 12 in away seems to be doing good and i think any more than 2 under one light is gonna be pushing it just my opinion

ok thx alot + rep
