Beautiful plants there man. I saw in one of your other posts thats RD Starkiller? Just started some 501st og myself, about a week in.
As you can see above, those cobs are fantastic.
You can also order these pre-wired kits that you just create your own mounting for. Easy to do, same thing (you can substitute for the 3070's if you want) and significantly cheaper. Ive been looking into some myself. Those gogreen's do look nice though, very clean.

ya,. actually i started off with the intent of building my own Cob, but i am not very hands on and have vvery little in the way of tools...so i just shopped around. The go greens are priced fair actually, i feel, because they come with top of the line hardware, and there is about 350 bucks adding up in hardware alone...and then hes got overhead, and labor, and material, etc....they go for just over $500. i know you could do it cheaper, but i feel he is fair.
Man, COBS are where its at though, i will NEVER use another "full spec" led. i knnow they do work. but i have just been spoiled with cobs for sure! They do compare as they claim...like my 200 watt 4 cob light i am using is to replace a 400 watt hps, and it really would REPLACE it....and you will get similar results, if not better, and the quality of the bud is phenomenal. Im sold. Main reason i got into them was because i was tired of battleing heat....and that is a thing of the past now! i have had countless crops that were heat affected, and it really hurts your yeild, and your quality. Heat is a motherfucker!
Good chatting dude...follow me if ya wanna follow along my current grow!
