It is actually an old school vertical parabolic, 36" variety which have become impossible to find. It's actually about ideal for a single high powered cob.

So I'm assuming that there aren't many solutions for 200+ watt single chip configurations? Interesting, I'm really wanting to replace a 315w CDM that I have with a single COB using the same reflector. Looking into how to make that possible. Any thoughts on the Luna cobs vs citizen at the...

Lowes and HD both stock 6061 aluminum flatbar, angle, and C-channel. However they are priced through the roof, and dimensions can be spotty. I'd actually recommend using your google fuu and visiting some local metal shops around town. The aluminum from the metal shops is usually 1/4 of the price...

What sort of heatsinks are you using to cool those Luna's? Am I correct in assuming you're running them at 300w each? Any thoughts on using a citizen CU550 or 3618 at the same power levels per chip? Impressive plants and tests thus far.

Oh I'm aware, but that doesn't seem to be the case here. See they aren't really stretching that much at all really, unless I'm mistaken. The parabolic reflector is the same diameter as the tent so I'm guessing that helps along with being the 4200k bulbs from advanced tech.

Growth has been explosive under my lec, but im not sure weather to attribute that to the light or the soil. Ive kept the light at the top of the tent to slow it down. To no avail it would seem

Haven't had a chance to hook mine up and play with it yet. However from the data sheet the 5vsb line is supposed to be able to provide 5v@500ma. Looks like the RC line can be controlled by opening/closing the circuit or by using a 5v signal. The 5vsb line I'm assuming is intended to provide...

I'll need it, many parts still aren't here yet.... SOON! Probably will have to retrofit the cooling partway through. I've got a TGA sonic screwdriver clone ready to roll though, just setting roots. Ready for their master to hurry up and finish her new home.

They work surprisingly well for that application.

.....ACTION NOW!

I'll be growing some lettuce under CXB's in a few weeks. For now a picture of my first few cob units. No lettuce, nothing fancy, just some gen 1 vero 18's @1.4 amps. Please try to ignore the fire hazzard wiring =/

@hyroot What is your thoughts on comparing blumats in fabric pots compared too the SIP method? Both seem to be aimed at automating watering via different methods. Assuming rols and water are the only things being used.

I vote for b, but im biased

I'm just going to mainline for 4 tops, run a 4cct cob and hope for minimal stretch? We shall see :P My 120x240mm radiator is not going to fly, hopefully the 80mm rad and associated parts get here in time. Do we have to run the same light source throughout the comp? Or can they be swapped out...

Leftover pandafilm from a recently deconstructed room. Along with a pair of 22 inch zippers from the hobby store. Going all out as you can tell :mrgreen:

Well I built my box today. In the name of simplicity I made it out of particle board rather than drywall. Slightly under dimension on the inside but I figured that wouldn't be an issue. ~11x11.75x22.5 inches on the inside.

Worthy mention. As with anything you should always understand the risks of the DIY approach. https://www.rollitup.org/t/dealing-with-fan-failure.864460/

April 10th-15th should be fine for me.

I have different plans if my ebay purchases get here in time. Just have to ponder the meaning of the box, then work from within. Gonna copy observe and report, should be interesting :p

Spackle and paint makes a carpenter what he ain't. I'll need tube of the gallon by the time im done lol May I ask what the point of the screen is? Im not going to do the hole idea but im not following your thoughts
