Hi! The other day I bought Plumeria seeds, but I couldn't buy a heating mat so I did one myself with an aluminium board and a fridge/freezer heater wire and I managed it to have to options. of around 20-25 degrees Celsius (which I believe is 77 degrees Fahrenheit) and 35-40 degrees Celsius (104 degrees fahrenheit) And I was wondering, can Plumeria seeds on germinate on the hottest temperature my mat produces? or should I keep it in the 20-25 degrees option to germinate the seeds?

thank you

I think the hotter setting would be too hot; I would stay in the lower range.

with Hetty. 104f would kill any seed.
