Jiffy Peat Pellets
I've always liked Jiffy pellets for starting seeds indoors, especially when I have a tight space and want to grow a bunch in one area without making a big mess in my kitchen. I always thought it was a win-win scenario, since the pellets just mix in with your soil and the netting dissolves over time, but it turns out that the netting doesn't dissolve as quickly as one might hope for.
