i know use mylar etc etc , im broke as fuck no transport and no hydro shops im using cfl , should i add tin foil to reflect the light ? i know its a nono or have been told that but its all i have and the wood of the cab is holding heat in. :S
 
lol why ur so mad !!! its not that complicated , u can use the silver plates above the lights , and foil on the walls . did you know what plates i mean ?
 
Only thing about foil is if its crumpled it'll create hot spots and burn your plants. If the enclosure is fairly small I'd just not do it at all.
 
I used tin foil for about two weeks during the seedling stage, but then I went to walmart and bought some emergency blankets. They are only 2 something dollars a piece and they are made of mylar. I have about 5 of them now in my growing room and they work great. If you have to use tin foil just make sure to check your plants for hot spots, but I really would try to get some mylar.
 
make sure its the shiny side, not the dull side, and yea try to not make creases in it (dont let your gf help basically....)

Edit: or paint them walls as white as possible.
 
aluminum foil only reflects about 50% light. Flat white paint or the dull side of poster board would be much better ~90%.

and the emergency blankets is a great idea.

theres a pic of the cab in my sig let me know if u think i should bother. :)
 
So the thing about aluminum foil or tin foil is that when used to reflect light because of the bent edges (basically impossible to avoid) this directs the light into points which may or may not create hot spots on your leafs.

I had white walls in my cupboard which i heard was fine, but decided to cover the walls with a safety blanket i bought for £2-3 from amazon i think, one blanket managed to do my with grow area, its worked fine with no issues really cheap alternative might be worth a try
