I grabbed a roll of aluminum flashing from a home improvement store. Made one out of that. If you want, you can polish it to a mirror finish. (thats a great stoned task! wax on, wax off)is it better to just hang the lights over the plants. or i have a peace of cardboard that is covered in tinfoil and then i cut holes to hang the light through so the light just reflects down and hits the plants.
should i leave it like this of just get rid of the cardboard and hang them.
