stone which does not sink in water?
I mix 1/3 peat moss..1/3 vermiculite...and 1/3 perlite to start my seeds..this is not the main medium after transplant but while seeding out.Perlite and vermiculite is available at wal mart in small bags for 3.99..Home depot has huge bags of both for 12.99 of each if you want to actually put the medium in the garden itself..vermiculite and perlite both retain water, and keep the soil loose so the plants can grow without strain...Outside I use 50/50 mushroom compost and topsoil for my large areas..I buy it by the truckloads rather than at a garden center in bags...Here are a few pictures of my veggie garden and herb beds..all the seeds were started as I suggested...
