Iv got a 250 watt hps and am looking to build a tent. I was thinking 6ft wide 5 ft tall and 3 ft deep, is this good dementions?? Im planning on doing a scrog grow. iv got all the materials priced out but i cant find and poly???? I did however find thick black plastic that would work perfectly. Could i just paint the inside with some spray paint or something TIPS,HINTS, COMMENTS Please

If you pant plastic it will flake off if you bump it or if the fans blow on it. I would suggest finding some mylar, or finding some white bed sheets. the only problem with the sheets is it will retain moisture and cause mold. I have seen white plastic table covers that might work.
