Ok so i figured i would start a new journal here just for my led stuff since it has taken over about half my grow now lol.
I been using the info gained from supraspl,growmau5,tags420 (greengenes707) and northerngrowlights.com to build a bunch of diy cob light bars.also shout out to bobbyg who has answered alot of my silly questions as of late :)
These cree led are turning out some fanfuckintastic plants and i plan to move towards a grow room with 80% cob lights and 20% gavita fixtures with both mh and hps lamps to cover all the spectrum.
Anyhow heres a few pics to kick it off and now that winter is here i should have more time to document whats goin on.

I feel the need to pay it forward so if you have any questions feel free to ask,if i dont have the answers i can prob direct you to a good place to look.
First pic is kinda old now,its bigger with 7 tubes laying idle....dead soldiers lol

So it looks like your building mostly 5 cob bars?what are you finding as far as number of cobs to replace Hps lighting?what is the cost difference?where is the best place to get the parts to build these lights?do you still hunt or do you just sit in a little room soldering?lol.

im headed north to hunt tonight :)
yes motly 5 cob bars based on driver eff and me liking the 1050ma meanwells.i have some vero 29 gen 7 builds coming soon so some will be 4 cob builds,some will be 6
i think 450w cobs kills 600w hps and my 540w are spanked the 600w badly lol.cost dif is hard to figure,for me its a huge savings on lamp replacement and a/c bills
i will list lins to buy this stuff later ,,mama said get offthe pc haha.

no soldering if you dont want to,everything can be bought plug n play now.i will list those parts aswell.peace

Fuck yes they do.
Good to see you around again. Good luck on the hunt...
Haven't made up my mind if I will hunt or not this year. Getting lazy in my old age.

Still interested in the startup costs of building a replacement for Hps,if a 450 replaces a 600 that's a savings of about 25% so pretty close to 315s?
Well start up costs could range from about 450 on the low side to about 550 on the high side.just depends how you build it and how efficient you want it to run.i built for for over 50% eff and it cost me a little more up front. But my 535w setups smoke any 600w hid setup.i have dropped my total lighting power from just over 12kw to under 10kw now and haven't lost a gram of weekly yields, in fact they are going up. My ac is running less now and shorter cycles so i know im also saving there.
But im not sure if I understand your question about 315s ?

Hey Six, I have a question, do LED's run as cool as the industry would want us to believe? I am subbed to follow along on this thread and so badly want to make the move for many reasons. So if you'll have me along for the ride I will have lots of questions . I hope ya dont mind. :)

some do some dont haha.the mars hydro panels dont run cool at all,but some of these new cob setups driven softer like 700ma and 1050ma run very cool if the proper heatsinks are used.and yes if you run them properly at high eff # you will see more lumens and less heat watts then you can get with hid lighting.been a minute since i did an update here,brb

So as soon as i get some time i will be doing a build with these new square heatsinks from northern grow lights and the bars i have been working on. These bars have had some changes since the first set and i changed how the plasma cutter runs around the plate so it spends more time cutting and less time moving from hole to hole.plus a found a guy that can bend 1/8 in and 1/4 in plate for me so i made another tweak to this design this week,just waiting to get those back from the bender.should be kinda cool looking but heres the new heatsinks robinn @ngl is selling

For now i will prob build one out using the prototype bars since i still have a few laying around here that need to be drilled for these.

So it will look similar to this^^^ but different heatsinks and i plan to use the vero 29 gen 7 cobs on them.stay tuned
