Is there a maximum temperature beyond which cacti seeds will not germinate?
The reason I ask is that I have a non-thermostat propagator and on putting a max-min thermometer in discovered the temperature was occasionally reaching 95F. I have 36 individual square pots in there, of which 7 have so far germinated after 10 days, but i thought maybe the high nineties might be a bit excessive for certain types.
If they have been subjected to "too high" temperatures is it worth shifting them to a temperature regulated propagator at 75 to 80Fish or will the seed have been destroyed?

Most Cacti and Succulents esp. Ariocarpus, Copiapoa, Eriosyce and thinking of branching into Asclepiads!
