Default Re: Alternative Black Substrate?

Buy two bags. One bag wont do it. I recently did a 125 and was surprised how dense this stuff is. I predict that you will use all of both bags. Some people complain about cleaning it but I just put it in a big rectangular (40 gals. or so) tupperware container added a little detergent, shoved a hose to the bottom of the container and gave it a bit of a stir and left the hose on low so there was a constant but slow overflow. I checked it a few hours later and it was clean. They spray it with a light oil to reduce dust and the detergent takes care of that. It holds plants extremely well especially if you are used to SMS or Schultz AS.
