5 Gallon Bucket Mushroom Growing Help!

Hello everyone!  This is my first time growing blue & pink oysters from a 5 gallon bucket.  I have two buckets, drilled many holes in them, used aspen wood chips (pasteurized) and 2 large backs of the grain spawn.  I think I have gotten my first flush of both buckets.  I moved them outside in a fully shaded spot in a corner by my house. I mist them 2 times a day.  I am in Iowa, and it is usually around 80 degrees during the day and 70 at night-very humid right now.  It seems like my mushrooms don't become fully grown before they start to shrivel & darken a little?  I'm wondering if it is too hot for them, or if they need more sun?  Maybe I'm watering them too much?  I have also found some tiny black bugs that i try to get out with water.  Any help would be much appreciated!!! Thank you all!

Sounds like they could be drying out during the day or the little black bugs could be eating them...If you could post pictures of the bugs and your mushrooms, that would help us diagnose the problem. :)

If you're using mid-high temp strains should be fine fore you climate, but from your description I think they don't have enough moisture. If you don't have any climate control, make sure that you keep em in the shade and not in direct sunlight. Also best is if you grow them in a closed chamber with some passive air current and not in straight wind
