315w

The leaves are all droopy and yellowing followed by brown spots on the leaves. This happens when the introduction of the CMH happens. Switching fully to CMH but want to know how to remedy. This has happened on the last 3 runs. Even though the plants look like crap they still finish better than...

Here we go. I've converted a closet into... a grow closet! ☺ there's about a square meter of floor space, and something like 1,7 m of effective height. I bought a 315w CDM lamp and a "bloom" bulb, I just didn't have enough money to buy the grow bulb too. So the red one will have to do also for...

Howdy y’all, first time posting on here. I’d like to hear anyone and everyone’s thoughts on what i’ve got going on. So, basically i’ve got 6 x 315w LEC’s over roughly 140ft^2. I’d like thoughts on my crossover and spillage of light. Looking forward to seeing what y’all got to say. Thanks! CL_IV

4x8 tent but only using half so I can start a some what perpetual harvest. Currently using 2 315w cmh in that area. I just ordered a third one this morning.. 6 in fan/filter that works alright. Installed a/c in bedroom for cooling purposes. I use one wall mount fan . Probably should look into...

I'm having trouble finding a simple explanation of the difference between the Philips CDM T9 and T12. Also, the difference between Agro and non-Agro. Can someone please explain it? I know someone already asked about this on here a few years ago but, I didn't really see any clear answer. Maybe...

Is it possible to use 3100k & 4100k bulb simultaneously in a 630w (315w x 2) unit? I understand 4100k is for veg and 3100k for flower. I figure broader spectrum with both bulbs in use. Anyone doing this or are most of you cmh users running 2 3100k in yours? Thank you for your inputs! Apologies...

So here goes, I've completed a few grows now with mixed results, so I have decided to start a journal to keep track of what I'm up to. So I have a 4x4 for flower, 3x3 for veg, and a 2x2 for seedlings and cuttings. In the 4x4 I have the 315w cmh dual spectrum a 5 inch filter and exhaust fan...

Hi everyone, This is a completely fictional story I made up about growing marijuana for fun. I have never grown or smoked marijuana in my life. Any pictures I post are stolen from the internet. This is my first serious indoor grow. I'm growing feminized blue dream under a 315W CMH, 12" from the...

Hey Guys, Brand new to cmh but it's looking like the best way to keep temps in check and still get results close to that of a 600w HPS in a 3x3 space (supposedly the perfect coverage area for these lights). When I was looking at the 600W, I assumed I would have to get a 6" inline @~450cfm, fan...

starting this journal on 12/12/15 at 3:33pm haha. The future is bright for my little personal grow. After my first harvest I learned so much that i wanted to refine it this go around, so on to my journal. My flowers are in day 22! Equipment: 2x - LEC 315s 2x - 4x4 Gorilla Tents 2x - 6"...
