Hi, I recently bought an aerogarden for my first time grow with an additional ten cfls. I have just about everything set up, but like an idiot, I let the folks at Canadian Tire fix my car. My aerogarden was in the trunk and all of the sponges are totally screwed up (either covered in something or broken). I was wondering what would be the best alternative as a growing medium. Also, what are some good nutrients to back up or replace aerogarden nutes? Thanks and rep to everyone that helps. kiss-ass
