the good thing about rapid rooters...they are made of organic matter, and gypsum, to hold it together. I find them too expensive , but great tools for growing. You can place any starter cube in dirt or hydro.

I have aero cloners, but I use rockwool, and trays, no wilt, no dome. spritz daily. Cloners are a pain in the Butt. Anyone want to buy mine? Just kidding...Sundance. Don't have a hissy.. LOL
