Notice, I didn't say CPs, I said plants. Plants in general need a medium that fulfills their nutrient requirements (negligible for CPs, but not all plants) and their water/air requirements (this is where the structural aspect comes in.) There are plenty of nutrient-free clays, but most CPs won't grow in pure clay because it doesn't drain, aerate, or yeild easily to roots.[b said:Quote[/b] (FlytrapGurl @ May 29 2005,12:55)]I thought CPs didn't need nutrients in the soil.. ?
