Can i use led en or noif you cant vent out the heat through a ceiling or window dont go hps or metal halide, use cobs leds they produce good yeilds and are way better than the leds you mentioned. they also produce vertually no heat so you can vent straight outside your tent (after carbon filtered of coarse.}
Can i use that right though the grow enFor a 3 x 3 foot tent ? One 315 watt CMH lamp would be a good fit. If you do go LED you will need to spend twice as much, unless you buy those cheapo Amazon leds. (Don't buy shit!)

This 1 isit budYes.......my first grow I used a 315 watt CMH light in a 4 x 4 tent......seed to harvest.......in a 3 x 3 it would be excellent.
Yes....a phillips or hortilux bulb will fit ANY cmh light fixture. 3100K spectrum is best for 12/12 but can be used seed to harvest. The 4000K spectrum bulbs are best for VEG state, not great for 12/12 but will work.So i can buy that and change bulb to Phillips or hortilux was it like on letric en
You want negative air pressure inside the tent. Twice as much exhaust CFM as intake CFM/Wa size filter would you use but plz
