As you know I am not the best grower, but cobs and organic soil changed everything!So I've been waiting for one of you guys to go there because I'd like some opinions myself on this subject. My old digital crapped out on me so I'm back to my trusty magnetic for now but I do need to upgrade aaaaand, double up. As well as how you like them, I'm trying to determine the equivalency to a 600. I plan to run 2 4x4 tents/rooms. I've done some research recently, along with my daughters very bright boyfriend, and we were looking at COB's, particularly that high end brand (the name eludes me) and have no problems taking on a DIY. So mainly, are they worth the money and how do they produce. I hear less yield but more frosty and potent. I'm into that if I can make it up some way, like longer vegging or something. Anyway, what say ye 600. Appreciate the input. Thanks.
Cobs are definitely a higher initial investment!I used the 315's for the last 2 1/2 years, now using the 3590 Cree COBs which are the higher end in the COB world but will likely use the CMH mid winter for some extra heat, I want to try it mixed with some COBs.
CMH is easily capable of 1.5 gpw with clones of any decent strain if you're going for yield. I do a lot of variety and my lowest returns in pheno hunts from seed with no training still got me 1 gpw+, they won't replace a 600 straight up imo, more like 450-500w equivalent if you have your hps environment dialed in. Each 315 in a hood can cover up to 3.5'x3.5'x3.5"H well. Quality is top notch and density is good or they wouldn't pull those kind of numbers. If your room is setup to handle hps these would be easy to manage, more heat than COBs but less than hps.
3590 COBs from what I've seen so far match or exceed the CMH yields watt for watt. What has sold me on them though is the quality is even better than CMH, for some reason terps on strains I've been running as long as 3 years are clearly louder, very noticeable difference (haven't changed my environment or methods so have to attribute it to the lights). For these to replace a 600 you're good with ~400w to match or exceed your 600 output and top shelf quality. Heat is less and you have to consider that, particularly if you're moving from hps. It can be good like in my case running 630w of CMH was stretching my room and sometimes difficult to manage heat. It could also be detrimental in that less heat = higher humidity so some adjustments may be needed.
Price wise the CMH is ~$1.25-$1.50 per watt, COBs are somewhere around $2-$2.50 per watt and continue to get cheaper particularly if you DIY. Both are a bigger investment up front but you get the returns pretty quick with their efficiency/gpw. You can either run less wattage and get the same yields or replace watt-for-watt and increase your total output.
Haven't checked them recently but I bought some at both these places, they carry a good stock and growershouse has 10% off promos all the time including LEC's. If you're buying any quantity both will drop their prices, grabbed 10 Sun Systems 315 240v's for my son and negotiated a good deal with BGH a while back. Right now through year end is a good time to buy, lots of them try and clear out inventory for year end.I'm inclined to agree with you. I recently fired up a 315 cmh for a breeding project and it will give the 6 a run for her money, just in a little smaller area....and I'm going to replace a 1000w de with 2 of them.
Does anyone have any links to sale priced LED's?

Wow! Great info guys! Thanks, and thanks to GroErr for taking the time explaining it that way. It helped a lot in steering me. I have some more questions but I'll get to that later.
I was doing some LST'ing on a lady last night who was topped a few weeks ago now. I came up with this idea the other day and thought I'd give it a try and it worked really well. These little things have saved my ass so many times with little projects here and there and once again, they come through with another use. Drapery hooks.

No, they don't do that. Cloth just seals around the pin, besides I do huge flushes in these and the only direction the water goes is down.You just put holes in your bags, water will pour out , not a biggee as it should get sucked up again
I chop up coat hangers and do the same thing. 1 hanger can make a bunch of thoseWow! Great info guys! Thanks, and thanks to GroErr for taking the time explaining it that way. It helped a lot in steering me. I have some more questions but I'll get to that later.

Thanks. That's only one lady though. She split into two (not topped) and grew the two stalks. One stock is round, the other is flat.Nice looking ladies and cool pics/video
Oh yeah. They're all individuals. That's why I decided to start giving them names to label/track them, just like a family.Funny how they express themselves sometimes
