Im almost finished with building my new grow cabinet and i have a question about CFL's and reflectors.
Is there a point in covering inside walls with aluminum tinfoil (mylar in not available at the moment)?
Since CFL's only works when close to plants and lights (2x 125w CFL) are fixed at the top of my cabinet (size: 1 foot deep, 2 feet wide, 3 feet high, made for growing 2 auto's at the time) i guess i should have tinfoil only at the top, where the lights are. Also ill have some low watt CFL's on side with their own reflectors.
Also, is passive intake alright with cabinet of that size? For exhaust im gonna have 8cm or 12cm PC cooling fan (havent decided on size yet.) with some DIY carbon filter.
