IMPROVE MY SETUP!! stimulus check

Well i just got my stimulus check, taking about 300 of it for improving setup. what i am running now is 1 3ft X 3ft X 7ft tent with a MH for veg and a HPS for flowering, have 6 waterfarm buckets in there. i have a carbon filter, inline fan cooltube. im thinking about getting some better refective material for tent, maybey just starting a second tent , or investing in a cheap portable a/c. post your recommendations for what i listed or give me your ideas. thanx boys and girlskiss-ass

I would either get the second tent and make a new grow area or get the a/c or other toy for this tent if heat is an issue. I strongly leans towards making a second tent though so you can veg in one flower in another and get a cycle going.

what are your temps in there? a 2nd tent would be nice

well temps have been around 85, found a portable a/c for 65 bux, definetly not the best but in a smaller area it should be perfect, second tent seems real nice right now since i just outfitted my closet with a badass t5 floro system so i can veg enough to fill 2 tents, with alternating flowering times it seems perfect
