Been noodling on design of two grow tents. Decided on two tents 3ft wide four ft deep six ft high. Plan on one 90 watt UFO LED light per tent. For CO2 enrichment I plan to put a fermentation jug in each. For ventilation I plan on a tee shaped vent tube with filter box and fan at end of center leg of tee. Plan to control fan speed / cfm with a dimmer. The 64 thousand dollar question, how do I know how much air to exhaust without wrecking the passive co2 enrichment?

Those UFO's won't be enough for a 3x4 area. Even together in 1 tent. They compare to 2 50w hps each. Do yourself a favor and get at least a 400w HID per tent. It will save you alot of money and your yields will be much better.

Agreed, this is not enough light for even one tent, let alone two. You will need at least a 600w LED (~$2000 each) for each tent to get started. Or two 600w HPS for ~$500 total

Yeah, for a 3 x 4 area you will want 600 watts. With a 600 in a tent, you are going to need constant exhaust, and that will suck your C02 out with it.
