I'm also doing a test run of a 315 cmh in a 4x4 , seems to be doing ok but i feel like more light wouldn't hurt. Do you feel the same about maybe having a second cmh in a 4x4 for max yield?
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. :) 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.

Heat test has been run. 6" High CFM exhaust set on high, passive filtered intakes from the cool basement. Isn't really enough. Steady 86 degrees, it's doable, but not ideal. I might need glass.
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

That would work until summer hits, then I'd have to reassess at that point. I run enough electricity, I hope to not get AC involved, dehumidification is bad enough.

If the glass will block UV B, then it kinda defeats the purpose.

We're you growing soil or hydro? If soil, what size pots?

I just got an ushio 4200k and it has a flicker on full power, it's extremely faint and fast but its there. I tried with and without the timer, and a directly into the wall outlet. Still there, but it goes away on medium 245w or 190w power setting. Made sure the bulb was tight twice. I did notice one of the bulbs contacts looked burned or like it had arcing? My other bulbs look good and the contacts are clean. Any idea? Think it may be a bad bulb.

I added two LEDs to my 315 cmh 4x4 tent, seems to be doing a good job so far

I grow in an autopot system. It is like a bottom feed hydro system.

I have done 50 50 coco perlite (worked great)
50 50 hydroton coco
33/33/33 hydroton/perlite/1 inch rockwell cubes

They all worked good :D

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.

Does anyone run the 210w CMH?

My veg tent is a 3x3 with 8 T5 2 foot bulbs. It does fine just seems a little slow. I realized for just slightly more power I could do a 210w CMH and get much more quality light.

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!
Canuck seeds. I bought a bunch when they went on sale. After this round in a couple of weeks I am going to use up my auto freebies. 2 auto amnesia (white russian auto) and a cheese and one of the kush autos i have left.


I will growlog 4 autos under a 3100 CMH in a 4 x 4 when i get it started. These are 4 footers too so they should be nice.

The seed hoard is going strong. I have Jack Herer, Train Wreck, Raw Diesel, King Tut, Sour Kush, Cheese, White Rhino and Northern Lights in fem seeds left. I should be good for a couple of years at 3 or4 plants a cycle :)
