No I did not bust the other sterilizing soil.
So this time I went 4 minutes.
The temperature reached 198 F, just under the toxic level all the references say you want to stay away from.
I wrapped my little bundle in a bathroom towel and took its temperature every 10 min.
10 min 188 F
20 min 178 F
30 min 170 F
I'm starting to see a pattern. I'll leave the little baby wrapped for the afternoon (at least 2 hours), then I'll unwrap and let it cool.
I'm seeding tonight so I will add to this post later on, the quality of the germination. I'm itching to plant my tomatoes but I think I'll wait another week.
