So far in my testing, both tomato seeds I started in the wonder soil came up in five days. Also, both tomato seeds I started in potting mix came up in 5 days. Tie ball game. Round 2 has started under the lights. This is where I hope to see something different because of the additives to the wonder soil (worm castings and whatnot). As long as the plants do equal or better than the potting mix, I will be happy, since I like the texture and the fact that it is so easy to store the compressed blocks.
