Hey folks, I've decided to begin construction of a new grow room. And in the words of Oscar Goldman, "Gentlemen, we can rebuild him. We have the technology... Better than he was before. Better, stronger, faster." My problem, however, is that I'm not quite sure how to set up all my equipment in an effective manner. Here's what I've got to work with: A bulky A/C unit A Canfan, a few misc fans, and a CO2 setup Two exhaust ports leaving my house I will be constructing the room with a sturdy 2x4 skeleton, then erecting the walls out of that black and white poly material. The seams will be duct taped in an effort to make the room as air-tight as possible. The hood, a growzilla hood containing 2x 1000w bulbs suspended from a light rail, will need to be exhausted. A large A/C unit will be in place, drawing air from outside the room, not outdoors. CO2 will also be ran. My question is, how do I effectively exhaust the room using the provided items without depleting my freshly injected CO2, as well as maintaining the smell? Thanks! Peace & Love -AR
2000w in a 4x2 area is way too much. 1000w is enough, and still a little overkill. But, I am asuming you have what u have and do not want to get more stuff. So, you MUST aircool your lights, and have the ENTIRE light aircooling system sealed. What size hood do you have, it must be at least 6" to work correctly. You should pull air from outside your grow room, thru your lights, then exhaust it outside of the growroom. That should take care of your lights. Now to venting the rest. You could setup your AC in the room. I see that it is digital, so using a CAP controller to control it will not work. You will have to set the temp on the AC unit yourself and hope it works correctly. You will need an exhaust fan (6" tied to a carbonscrubber.) You will need a CAP CO2/humidity controller. Plug your Exhaust fan in and set your humidity to your liking. Plug the CO2 regulator into the CAP controller and set your ppm to 1500. Now, when the exahust fan kicks on, it will stop your CO2 injection into your room until the fan kicks back off, and the replensih the room with CO2 back to 1500 ppm. I perfer a CAP controller with "fuzzy logic". If you read up on it, you will know what I mean. They are pricey. You MUST have your entire grow room sealed well in order to fully utilize your CO2, otherwise, you are wasting your time and money. So, there you go, thats what it will take IMHO.
