If I were to do it again I would run 2 tents that were 3 x 3 with 2 plants in each and a 315 CMH. But I am very impressed with a single 315 and it works great.
I suppose I could do a cold air intake set with a temp controller I have...I hate making things even more complicated, but I have the equipment and a problem with being obsessive...lol
The glass does block UVB. I've grown with and without the glass in place on my 315. The plants still finish out nice but noticeably less potent than buds exposed to UVB.
We're you growing soil or hydro? If soil, what size pots?2 might work well but heat would be an issue. 12 to 14 oz per run from my 4 x 4 with a single 315 is more than enough for me.
2 315 cmh & 2 600watt hps
How are you handling the heat?
I added two LEDs to my 315 cmh 4x4 tent, seems to be doing a good job so far2 might work well but heat would be an issue. 12 to 14 oz per run from my 4 x 4 with a single 315 is more than enough for me.
I grow in an autopot system. It is like a bottom feed hydro system.
Cold Air Intake works. Set a low limit of 75 and high limit of 78, set the inline fan on low, keeps the average 76-77...fan runs on low maybe 40% of the time. Not bad until summer comes. Except I have to fasten the door on my box now because of positive instead of negative pressure. I did notice a bit of a draft with the fan off, so I might have to set up a booster fan to mix the room air into the box during lights off to make sure temps don't dip too much. I think I have a spare temp limiter.
Not sure about the performance of those, not like the Agro 315's
Actually they are relatively similar. They even make a 210w 3000k bulb much like the Agro spectrum 315. You have to have the option to put your ballast in 210w mode. Mine is an actual Philips CMH ballast and they have that feature built in. I decided to go for it and will update with my results. I expect great results just like when I switched to 315 CMH for the first time. I think it could be the perfect veg light for my little 3x3.
Where'd you get your genetics? Looking great!The buds are fattening up and the trichs are loading up. Week 5 of flower on 2 white rhinos and a cheese. The 315 is all the light I will ever need. What do i do with the 3 other lights now
