Cheers for the info tom, will be getting a double freestanding wardrobe soon so airflow wont be a problem but as for now i have tried many setups with the fans i have, and atm i have what you said, 1 in, 1 out, but one of the fans is not too great but doing its job, moved the light closer but not too much, just going to gradually move it closer and when its right, its right i guess.

as for mylar, well we dont have wallmarts here but im sure ill find some but i think i will leave it for the wardrobe, main thing is to keep the plants happy!!!

thanks for your help, much appreciated!
