Seed germination in vermiculite
Perhaps this isn't very "experimental" but I read about starting seeds on top of a moist layer of vermiculite. Ideally the vermiculite is placed on top of the growing medium so the roots can burrow downward. But that isn't what I've done.
I've had no success trying to germinate some 2 year-old cuban pepper seeds (two weeks and no show), so this morning I opened my huge bag of vermiculite and put a quarter inch layer in the lid of a sour cream container and moistened it. Then put the pepper seeds on top, put the container upside down on the lid, offset slightly so air can circulate, and put them in my little heated grow-house.
If they germinate, I'll have to carefully transfer them to the planting soil, but at least this way, I'll learn if they germinate at all. Can't see what I planted and don't want to disturb them in case they're just being extremely slow.
I may end up with more pepper plants than I want! I'll let you know.
Has anyone here used vermiculite as the medium to germinate seeds? If so, how did it work?
