Ok, I just ordered 8 cxb3590 3500k 72v cd bins w/ ideal holders and lenses as well as (2) MW 700mA drivers from kingbrite for project overkill and I have a few questions.

Next step is the heat sink, heatsinkusa for sure, but what profile 10" or the 12" or the massive 10.8"?

I believe it is solid, but what gauge wire do the holders use?

Also what size carbon filter is recommended for the 2x2.5 gorilla tent? I have a 4" duct fan w/ speed control.

Also is Co2 generation worth the effort?

For the carbon filter find out your cfm of your fan and size the filter by cfm. You will obviously need a 4". The holders use 18-24 awg for wire size but it depends if it's solid or stranded. Google ideal chip local cx 3590 and download the spec sheet for more info on that. As for heatsinks depends on if your going for passive or active cooling. Check out the heatsink thread for more info on that. Good luck brotha

The fan is 164cfm I believe. Going with active cooling on the heatsinks. I'll get the holder specs as soon as they come in. What about Co2 gen?

I use 18AWG solid copper single wire....I used 20 or 22 Ga strand and the wires kept popping out of one of the holders.....just Fyi

If you are going to be pumping that much light out I would definitely say yes to CO2. You will have an area capable of increased photosynthesis but no increased carbon source. Remember light drives photosynthesis, nutrients help facilitate those pathways, carbon and water makes up the vast majority of the actual mass of the plant. Dry mass mostly carbon.

Ok.
Should I monitor the Co2 levels?
My cousin gave me a Co2 controller, well its more of a fan controller. It shuts off the fans and turns on the Co2 generation when the adjustable humidity and temp settings have been met. Nothing fancy just a box with two knobs on it. Would like to implement it if I can, but then again since I've went the efficiency route with the lights I was thinking maybe go with one of those 2-litre bottles I've seen. Idk. I have a feeling my wallet will decide for me after this light setup is finished.

I hate to be the bearer of bad news, and I'm not extremely well versed on the subject but I think you'd be tossing money out the window at this point to start with co2. since you're buying a fan and filter I'm guessing you'll be using that to ventilate your tent, co2 is only really doable in a sealed room setup with an AC instead of just inline fans to cool it. if you homebrew beer, do that in the same room, but otherwise I wouldn't put the ~$225 into a co2 system until I'd put a shitload more into an air conditioner.

As far as the size of the carbon filter, I just used a can 66 in a gorilla lite line 4x4 with the height extension, worked great, the downside being the weight of the damn thing, it's what convinced me to go with gorilla. I've moved it to a 5x5 gorilla (regular, not lite line) and it's good in there too, just had to switch the flange from 6 inch to 8 inch.

I would say a can 33 would be your best bet, but just by seeing that you're using a 4 inch fan, I'd say any filter that fits a 4 inch should work

oh wow, didn't read your post, I didn't know about those co2/fan controllers, that's really cool, I guess I'm the newb, and I have research to do
and possibly implement

I should have prefaced my post by saying I'm only on my 2nd grow right now

It's all good, that was solid advice if you ask me.

I'd also like to add that I have a portable air conditioner that I'll probably be running in the same room. In addition I've got an extra water cooler at work I'm going to pump my nutes threw a copper coil submerged in it to help control temps cause its hot a fuck out here in California.

DefinItely monitored and on an environmental controller. If you can a portable ac could be used in conjunction. But honestly CO2 uptake is increased with elevated temps. I accidentally left my exhaust off one night and temps never got over 94* in the tent. While hot and definitely not ideal for me not horrible if running CO2. So I'd test it out first because may not be necessary for an additional ac depending on how and where you're drivers are placed. Other option is the controller controlling an intake fan for an active intake instead of passive that is separate from the exhaust. So exhaust could be off during enrichment but intake able to draw in cooler air at the same time if temps get over mid 90s.

First a quick question before I give you an answer on the carbon filter question, Is this tent 5'11" high?
To calculate what size carbon filter you need the first thing to do is calculate the tents cubic footage. 2' x 2.5' x 5.92' = 29.6 cubic feet without CO2 you would want to exchange 30 cubic feet every minute which would mean you only need roughly 40CFM fan to achieve this but since you already have a fan and plan on going the CO2 route I think your fan is more suited for this as you wont be running it all the time you want it to exchange the air much quicker to deal with temperature etc. With that said you will reduce the operating CFM of your fan by approx 25% with the added resistance of the carbon filter. So with 164CFM fan x 0.75 (due to the loss of CFM of added carbon filter) = 123CFM So you could effectively go with a carbon filter rated up to 125-150CFM

It 5'11 ish, the math makes sense is there a certain brand you would recommend? I know Borbor suggested can brand im just trying to see what's best. Seeing as how this momma is smelling pretty good already and I'm still in veg I'll need to get a good system in place soon.

Don't have experience with too many of the brands but from reading posts the can filters, phresh, mountain air all seem reliable. Probably others that would do the trick also.
