View attachment 3660813 View attachment 3660814 I went from 1000 watts hps to 600w hps, sold those, bought 2, 315s, 110 volt... just finished my first grow with the 315s.. Here's two waterfarms a couple days before harvest, first first is Nirvana Blackberry, second is Blue Mystic..... Good example how different strains stretch in flower.. The 315 watt did a good job of reaching the lower buds on the BM...

Ok sure it's been ask, but lazy. Lol. This a 4x4? Awesome grow.

The lights were hung at about 24", first started at 30" then lowered.. That's gives me a good 32"x 32" , 45 watts sq. ft.coverage, though as you can see they really do try to lay down and spread the last couple weeks..... The screen they're in is 84"x 24",with a small plant under an advanced DS 200 led, in the center between... The two 315s are will be on a light rail next time around... I think the two lights, on a lite rail, can cover the entire screen with 3 Waterfarms under the screen.....

My one girl that has been flowering under the SS 315 CMH is loving life guys, have zero complaints on this light thus far.

Question has anyone ran one in a 2x4 tent? I am considering a second one for veg but don't want to just ditch a good tent for no reason already have the 2x4 on hand........

I haven't seen anyone in a 2x4' but I have an extra LEC after I got those Tasty COBs and I'm going to try it. It's only 5ft high but it's a veg tent so plants never get beyond 2ft. high. Tight but I want to try it. Not concerned about the heat, just managing the overhead in a 5ft.H tent. They'll cover that space fine for veg. Ideally you'd have a 7ft to run them up high and get great coverage.

Perfect brother please let me know my 2x4 is a veg tent as well, and I'd rather not discard a perfectly good tent to only spend $$ on another 3x3 if it's not needed. The layout of the 2x4 that I have at least has a lot of space it's actually bigger than 2x4 by a bit..... I don't mind the T5's but they run hotter than the 315 and use more power so...... still testing with them but the 315 in flower is on auto pilot while I am having to constantly check in on the veg tent and the heat I believe is causing my leaves to curl a bit and have a funky texture on my seedlings......

Will let you know, see if I can get at it this weekend. Can you not just take out a tube to manage the heat issue or would it not be enough lighting. Maybe too much for the space, can't remember the fixture you have in there.

maybe a little late to the party but does anyone know the ppfd rating of these lec's?

I haven't found any published claims other than 1.95PPF, not sure how to translate that into oomoles

i am now running 4 315watt cdls,cmh,lec what have you. each one has the 3100 k agro bulb.. 1 for my veg room, 3 for the flower room, i was running a mh in veg, since the switch it seems using the 3100k bulb alone kicks ass, in veg plants stay shorter and really stack on the nodes, growing outwards as fast as up wards, then flip to 12/12 the stretch isnt near what it was plants double the height in the first 2 weeks but the amount of nodes is amazing,,and if you top plants in veg,,,wow,, you need to really clip lower branches as the canopy is so dense that no light gets past...best gpw is with 2 315's, 30 plants, 842 grams dry,,,630 watt total...

Hey glad to see you back and growing! After a couple of runs with those COBs I've been impressed with both yield and quality, watt-for-watt with some limited runs I'm seeing about a 10-15% bump in yield. The most impressive factor for me though has been quality and loudness of terps from existing clones I've been running for quite a while, very impressive.

Hello i am pretty new here just trying to set up my first grow and just have a quick question for you if you don't mind. I've watched a video on YouTube where someone grew under identical conditions with a LED (not cree cob's) a gavita and and a 315w cmh and the thc levels were tested at 18.9, 18.5, and 22.5 respectively. I was wondering if you have noticed any loss of thc under your cob led compared to the cmh? I think it has to do with the UV produced by the cmh. I am trying to set up a small grow for my own medical needs so I don't need need a huge yield, I'd prefer quality over quantity which light would you recommend for me?
