Lagniappe

I just potted up a bunch of sweet basil in it. I'll plant a bunch of Genovese basil seedlings in it later tonight. I don't rinse it because I read that it's best to leave it be so that the dust will go to the roots and provide silica to your plants. hopefully, it will prove itself as a hydroponics media.
It's a darn good idea to pop a hole in the bag and wet the living daylights out of it before use. Then, you can pour the water into a container and have your insecticide solution all made up without the dust.
