So, some troubles have cropped up with the 512 Cell Plug Trays. I keep having keeps migrate UP thru the Vermiculite top layer. Im thinking just topping with my regular mix might be better.
For seedlings I have been mixing half peat, half vermiculite. I fill my cells, press down, seed, spray some water, top with V. and spray again. But after a couple more sprays the seeds starting coming to the surface.
Anyone have this issue?
