I agree with what's been said. Not having waste for a bit is okay. Temps do not sound ok. 86-88F hot side at the ground. 78-80F cool side. Humidity should be 50-60%. 75% okay in shed, but not sustained.

No aspen.

Soaking ok, but only with warm water - 75-85F - checked with a thermometer or temp gun.

A temp gun is how you should be checking your ground temps. Air temps do not mean as much.

Any other questions, just ask. We are here to help.

Good luck and keep us posted.
