How hot is too hot for seed germination?

Runningwater · March 14, 2016

Orginally posted this in the Pepper forum and then thought it might get a better chance of an answer over here. I was going to try germinating my pepper seeds this year before transplanting into starter cups with granular DE for a seedling medium. So I had pepper seeds in damp paper towels in a tupperware on seed heat mat, put a dish rag on top and didn't check them until about 24 hours later and it was much warmer than I expected. I'm guessing around 110 degrees? Have I killed the seeds and need to start over - or will they be OK?

Any advice welcome - want to restart ASAP if that's the answer - thanks!
