light deprivation lights out air circulation questions

ok so im intrested in doing light deprivation because iv got a 10x20 carport, an ez up, and a soccer goal frame i can do somthing with. id like to start with doing a little breeding with light deprivation using the soccer goal and just covering it with panda film but ill just be suffocating my plants for 12 hours without some sort of exhaust fan and intake ducts right? any suggestions what do you do??? really would like to avoid running a long extension cord and running a fan

Put an exhaust fan on top of the frame to draw out old air and replace with cooler co2 enriched air otherwise the stagnant air will stunt them and encourage mold.

I love Light dep grows, everything from metal trash cans for breeding seeds to simple hoop-houses.
I never had a problem with air circulation @ night, Just cover and un-tarp.
If you do have the luxury of having outlets next to your grow try it out

Hmm if I'm gunna run a fan and if I'm running wires I might as well put a little cfl on a timer in there also so I can sleep in a little past the morning time to pull the soccer goal off.

I was thinking this would be a better alternative than running mother indoor tent for breeding but honestly I'm not so sure. I may be be better of just making or getting a little tent to run in my room with a 150 watt I have laying around
