Hey Weedathon. First of all let me say what a bad idea it is growing with 3 other people. Yell all be done for the whole thing for only a quarter of the harvest. My first grow i dont with a buddy who i thought could keep stump but it turns out he was still dealing from the house without my knowledge. Baggie and scales = jail so he fucked me over big time. Cut my losses and moved out before the 4 plants were even done. Also half of fucking Ireland knew. So if you are gonna do with your buddies make sure they all keep stump. Its hard to not talk about your lovely plants after a few drinks. Regarding your window, build a window box like seen here Step by Step Grow Room setup to harvest!! Awesome Video!!

Good luck!
