How are these products on the hands when planting/harvesting plants?? I was trying to stay away from lava rock. Seems the sharp edges weren't conducive to skin.
hydroton and expanded shale are relatively smooth. Not like lava rocks. Maybe the people who use lava rock can expand on how easy it is to work with but i have never heard anyone complain.. Personally i dont spend much time digging around the growbed. I throw the seeds on top and once they start getting bigger i will pull them up and space them out better, then i pull them up when they are done producing. You may incur more root damage moving plants from lava rock but then again, you could just space the seeds with more care to spacing than i do.
