Yes, bumped up the thermostat to 25C and everything seems to be fine, as far as I know about 26 is about as high as you want to go but the thermostat has about 1C hysteresis so playing it a little safe (77-79).

Some point soon I want to try growing cyanescens/azurescens but having difficulty finding spores, if I can at least find a spore print then some agar work could be fun - I've never tried it with fungi before only micropropagation of plants.

Is there much need for supplementing humidity at this stage or is the limited amount of air exchange not too much to dry the substrate out?
