i want to know what type of refelctive surface woul dbe best to cover a room in. im going all out and spending as much money as is needed to grow my first crop with 2000 being my limit. i dont like the idea of mirrors just for the simple fact that i took physics ( didnt pass cuz i slept and understood a hella lot) and they seem like the best option to me at first but the heat and absorption of heat caused by them would i think cause more problems than benefits, but again this is just my logic speaking. i would like some ifo is all. is tin foil good? my room is painted white of course right now or what would do the almighty plant more justice?
