I use Ferti-lome Ultimate both for germination and when repotting. I just tried some refill sponges that fit in a 60-cell Biodome (I used a Speedling styrofoam seed tray as so far 19 of 20 seeds have germinated. I will try to grow these to the "selling" stage to see how they do. If they do well, I'll be able to grow 200 seedlings in about the same space a 1020 nursery flat takes up.
