thew funny thing is i have a massive pile of ornamental polished black rocks in the back yard in a pile from a gardening adventure. they are about 2.5 inches long.
the idea of rocks to hold down perlite just isnt ... well im just not feeling it. Seems silly.
ok so if i go the perlite route i take it they can wick (have capilliary action) how big should my air gap be? ive drilled holes to leave 4 inch gap, but new buckets with new holes will cost me nothing.
