Hey guys, i understand its preferred to have a reflector above the lights, i am using a closet for my first grow,its fairly large, and most of my money has gone to the major supplies, so i was wondering if there was an inexpensive way to maybe use a reflector? i was thinkining maybe tinfoil above the light, but i wasnt sure if it would keep in too much heat. Can anyone give any suggestions? And also i am going to be growing with soil, anyone have any good suggestions as to what strain to use? puhleeeaaaase somebody help, im almost ready to begin and i dont want to go in half ass.
