Now that I'm not so high on the "yes", I just realized that I need to do right by the B man. I'll run these testers first thing. Well, the first bloom run will be straight from seed and I'll use fems for that.. Need me the maximum on the first run! My jars are dangerously low. The first Veg cycle is definitely going to be the SSH X 88G13HP

What do you have planned for your led setup. Ive kicked the idea of building a cob rig around for a long time but im not even sure how much id need and if the heat savings would make it worthwhile.

Veg and bloom will each have their own version of the same light, 5x CXA3070 running @1050mAh. Bloom LEDs are 3000k and the Veg will be 5000k. The bloom light is already completed and its the coolest running light I have ever came across hands down.

A good rule of thumb is 1 cob per square foot of space that needs to be covered, minimum.

This thing was really easy to build. Tapping and drilling the heatsinks was the most stressful part. (Once I figured out to just slather them in oil, even that was a breeze.)

Because I had to get wire, and the tapping thing, and pretty much everything else needed to delve into this diy lighting deal, it wasn't super cheap. But now building my veg light will be pretty darn cheap. -About $250 more- and it will last forever and nothing on the market will beat its efficiency either.

I like the use of zip ties and pvc, this build is my kinda build lol.
The wiring wasn't hard? I have no experience with circuitry so that is what keeps me out of diy leds, would be an expensive learning curve.

1 cob per sq foot?
No matter how many watts the cob is?
I think with crimp on connectors and my previous soldering experience i could throw one together but its all the numbers and math that lose me.
My cabinet is 32" wide 50" high and 24" deep. How many and which cobs to be as cool as possible?

Almost exactly what size my bloom space is that this is going into. (the dimensions of the light are 24" x 22") cab is 30" x 26" x 63".
1/sqft is just a rule of thumb for the lights effective spread. Mine run @1050mAh which is the sweet spot for efficiency in my setup. IE, maximum coolness and minimum electricity drainage. (What I would recommend to you.) Many ppl choose to run these particular cobs @1400mAh to max out yield but will lose some efficiency.

You can do it! I am not an electrician by ANY means.. This is a completely solderless job if it needs to be. (I tinned all of my wiring, but its not even nearly necessary) I used the cob holders which come with a plug in type system. You just need to make sure that the wire is not too big of a gauge and I prefer the rigid 18-2 speaker wire as opposed to the stranded varieties.

I think you should grow the new auto flower strains....fast and fun...no need to worry about light leaks and stuff.faster yield too save 20 days.

The only reason I have fems laying around is from freebies or oooold purchases laying around. Even though this will be my smallest grow ever, I will still be chucking pollen here and there and ya gotta have the regs fo dat.

Now take a mini squirrel cage blower and mount in on top of the box 400cfm and pull air in from the back side low...this would draw out the heat.
I was planning to put a 6" hole on top, center front to suck air from. So the intake should be in the back bottom, at soil level?
