Fantastic!

This was my first time growing in buckets in a grow tent. Was very easy and they did even better after I got a humidifier in the tent! I just harvested my second flush. Very easy!

Yummy mushrooms, quick colonization, easy to fruit.

I'm a return buyer and I love growing any and all mushrooms, especially blue oysters, from the spawn I get from Shroomage - always high quality mycelium!!! Very easy to grow in buckets on my front porch.
