Is 3 x 315 cmh in 4x8 tent enough light or would the yield be lot better with 2x 630 cmh duel bulb lights?
4x8 tent cmh light setup

Hello,
I’m planning out a room and want to cover the a
Same footprint. I am also leaning towards CMH lights since the winters were I live are cold. I am going to use at least four 315’s or two 630’s. I am contemplating 6 315’s but that could be overkill. Since the footprint for a single 315 is like 3 x 2.5, I am worried that single lights in a row would fail to cover the four foot width adequately, which has me leaning towards x 2 630’s. I am impressed with the CMH light my friend is using to veg. I have not grown on my own in 35 years so I am reading a lot of forums and reading a lot. Good Luck. If I find out any info I will let you know.

Thank you for advice. Considering LEDs but worried about temps in winter. I am under impression that BTU per watt is same and maybe an over thinking it? My basement temps are about 65 -68 F in summer so afraid I might have to heat in winter? I am impressed with LED lights but also intimidated. I have never used one.

630's for the win. LED's are so overrated.
Thanks for your input. Appreciated

I know I would want at least 4 of my 315's if I ran cmh in my 4'x8'.
Go with what Renfro said.

LST can make almost anything fit
But if your doing that, I'd just go 2kW SE HPS and call it good.
It works.

His plants are pretty tall even with LST..... some say he needs a bigger fan too.

I like the size of the buds. Not alot of crystals and they look super fluff. Pounds like pillows. My crew had a cut of sour with buds like that. Not alot of crystals on theirs either. But 1 liter coke bottle tops.
