Update on Sterilizing Soil

We purchased a new microwave.  

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.
