Here it is. I'm gonna attach the reflectors and hang it tonight!

I went to home Depot and used this for my current build in progress: http://www.homedepot.com/p/Everbilt-1-in-x-96-in-Aluminum-Square-Tube-with-1-20-in-Thick-802537/204273939

4 cobs per hlg-240h-c1750b, so at full power that's about 60 watt per cob right?

Anyone have feedback about the spacing before I start cutting? Any constructive feedback is welcome!

Also, I was wondering what you all thought the best thing to connect all of this with is? As of now I'm going with nuts and bolts. I was going to rivet it all but I was at home depot and all i could find was .5" rivets, I'd need at least 2" rivets.

So after putting a lot of thought into it, this is the design I came up with. I plan to start building it tomorrow but am looking for feedback on if the spacing of the COBs is ok, it'll be for a 4x4 tent but I think the most plants I'll ever do in there is probably 10 in 5 gal pots. The flat...

Do you mix the insecticidal soap with the neem oil in the same bottle or are you making two bottles, one for soap and one for neem oil?

One thing I am really worried about is pulling all of this electricity from one outlet (there is only one in my basement). I'm going to be running 12 CXB3590s on 3 drivers @ 1750ma, a 6 inch inline filter fan, an in room fan, and potentially a small space heater in the winter. What amp and...

After some more reading and watching videos on how to solder I've found that https://www.amazon.com/Alpha-AT-31604-60-40-Solder-Ounces/dp/B00030AP48/ref=sr_1_1?s=hi&ie=UTF8&qid=1466872653&sr=1-1&keywords=Solder is the better option because it has more tin which results in a lower melting point...

Can someone tell me which solder I should use? Only difference I could see was the tin to lead ratio and the melting temp. I am new to soldering. https://www.amazon.com/Alpha-AT-31604-60-40-Solder-Ounces/dp/B00030AP48/ref=sr_1_1?s=hi&ie=UTF8&qid=1466872653&sr=1-1&keywords=Solder...

Some people are saying that 16ga is too big for the ideal cob holders, was that your experience? Can i use the same ga wire for the entire build or am I supposed to use different sizes for different aspects of the build? Sorry if I am being annoying.

Did the box come with the potentiometer? How do you tell what strength it's turned up to so that you can make both lights at the same strength?

I bought my heatsinks from Northerngrowlights.com and I bought my cobs, reflector and holders from pacificlightconcepts.com. Send them a message asking if they have stock. PLC was showing oos on their website but when I messaged he had some.

Also, for the end of the driver that plugs into the wall would it be better to use something like this http://www.homedepot.com/p/Leviton-15-Amp-125-Volt-Double-Pole-3-Wire-Grounding-Plug-Black-R50-3W101-00E/205165472 or would it be better to buy a 15 ft extension cord and cut the end off and...

I'm wondering which potentiometer I should go with? I see a lot of people using a 100k in their builds so I was looking for one of those. I was looking for one that had markings on it so if I had my 3 bars side by side I could put them all on the same brightness but the ones I'm finding don't...

After thinking about it I'm considering keeping these lights separate and making 3 4 cob panels so that I can control height better if a couple plants need the light closer while others need it further. Especially if I were to grow and sativa and indica at the same time I'd want better control...

Can someone please shed some light on some of these questions I have?

I think I might have been confused. Does the filter come filled with charcoal already? For some reason I thought I would have to fill it. Also, I have some questions about wiring this up. Should I use 18ga wire or should I get thicker 22ga wire? Also, is there a easy way to connect the 3...

Which one would you suggest? I don't care too much about noise.

I recently bought this fan filter combo and the filter came dirty (looks like charcoal dust) like it had been filled with charcoal before. Is that normal or does that mean this has been used? I'm not sure as this is my first filter and wondering if maybe they fill them to test them...
