Matt temperature

With the dome and mat you can pinpoint the temp and humidity. But there will be a lack of oxygen if you have oversaturated the medium. You want moisture but not soaked. We want germination but we are also fighting against stagnation of water via decay rate. Bacterial growth explodes exponentially above 77f doubling populations every 20 mins. If your oversaturated with high temps can create a race to the finish line for either disease vectors or germination. Just make sure as soon as you see green you give her air and dontt keep that dome on too long without letting air get where it needs to be. Best of luck with the babies.

25 C is a good Sweet spot:)
