So I decided to scrap my original plan for the control box. These ones I got are too small. I forgot I need to make room in there for the power converter for the fans too. I'm getting a couple of these so I can fit everything in. Also can't hurt to build this thing with a little style, right? I...

Haven't done anything with c02 yet, just trying to plan for it. Any way to use it in a grow tent while still using exhaust fan and carbon filter for fresh air circulation and odor control? Or will I just exhaust the c02 right out?

So I ran a test. We have light! This photo does NOT give you any idea how bright this thing is. PS - Do not EVER look right at these things. I was not prepared for the brightness when I turned it on. I am seeing checkerboards everywhere.

I do plan to use a fan for each heat sink. I am wondering how best to orient the fans, though. I am using 12v computer fans, do I just screw them down to the fins of the heat sink? Blow the air at or away from the heatsink? Mount it so it blows over the heatsink from the side?

So I am relatively new to growing cannabis and I am trying to plan for the future of my grow room. I am using LED lights that I cobbled together from available parts. I know with HPS or similar lights I could route air flow through a carbon filter, into the light fixture, and right out of the...

Boards are attached, each piece is assembled.. I need to cut out a spot in the L channel for these to lie flat and bolt those up then run the wires.

Good luck with your build @Axion42. Drivers are mounted on a kick panel that will live outside of the tent to reduce heat around the plants. I am also using fans to cool the board heatsinks. It seems that even if it is a mess to apply thermal paste over each board, I will only have to do it...

So I saw something from ledgardener last night that has me asking questions. In one of their QB videos, he says they do not require and thermal compound to work with the heatsinks made for the 288.2 boards. I bought a jar of that stuff to make sure I get max thermal dissipation. Is it worth the...

So my build continues... I made my kick panel for the power supplies, cut my aluminum L channel to size and got heatsinks mounted to the rails and secured with bolts. The last photo is a mockup of what I want this thing to look like when I am done. No boards or wires yet, just wanted to get the...

Started to build what I can, got one of the control boxes set up. No wires yet but it looks like what I had planned will work.

Thanks for the info. I had already ordered 14g wire for the run from the power supply to the control box where I have my pot and an on/off switch. From there it will be 18g to the boards but runs are short, 2-3 feet at most. I should be ok, yea?

OK sounds like I am trying to make this harder than it needs to be. Thanks all for the recommendations.

Well, the last of my parts are coming today. I should now have everything I need to start building my lights. I just did a ballast bypass for LED tubes on my t8 veg light fixture. 2200 lumens @ 18w in 4k color temp. Anyhow, 1 light down and the big ones left to go. I'll be posting in here as I go.

Hey all. So I have recently started my first grow in years, and only my 3rd overall. I am not to the curing stage yet but I am trying to plan ahead. Is it feasible to use a coffee canister to cure in instead of a Cvault or some such? I know I could just use jars as well, but I am after a way to...

Thanks for the recommendation. I did not originally want to order from outside the US but I could not find Lemon Zkittle from a domestic source. Grizzly did hook up the stealth, though. Made it through customs no problem. I have since found a couple of really highly recommended US seed vendors...

I recently got some seeds from Grizzly Cannabis Seeds. Lemon zkittle fem and gluebery OG fem. Shipping was fast with tracking info emailed to me automatically. 10 days delivered to the US, no problems with 3 free seeds (2x stardawg and 1x fruit tree). I also ordered some seeds from Sequoia...

Hey all. I happen to have a 6500k 6 lamp t8 fixture that will fit perfectly into my 4'x4' veg tent. I am planning my grow and debating on whether it is worthwhile to get t5 fluorescents or a cheap full spectrum LED for veg. I am already dropping a grand on my flower lights so I don't necessarily...

I am into DIY projects in general, but it is my hope that these lights will do me for a long time and I won't HAVE to build more for a while. Like my old man always told me, 'do it right, one time'. I get that they eventually burn out, just like bulbs but 50k hours is a long time.

Offer was accepted on the boards!, everything is ordered. :bigjoint:

Well, I did it. Parts are ordered. I am waiting on a response to my offer from Atreum but everything else is on the way. Hope they will accept $70 a board/heatsink. I am buying 8, hoping I get a volume discount. We shall see. One way or another I'll get the boards. They have them for $75 on...
