I just had my first flush and going to cook them up later! Just like the title says, it was a lot of fun growing Queens! And one of the best i’ve grown. There were a lot of big ones from my first flush and excited for the second flush. Will definitely check out the other kits!

Great tasting Cosmic Queen

Very delicious oyster mushrooms, but only has one flush, so too expensive for one harvest.

Delicious Mushroom!

Cosmic Queen required a bit more patience but it tasted awesome on pasta or risotto. Customer service has been top notch and I have learned a lot from Kylie and team. Will get more!

Cosmic Queen has taken the throne

Wow is this mushroom delicious. It grows these wonderful large caps and stems and yields a really good weight when grown in the mid 60°‘s with 92% humidity that I drop after full pin set. Really simple and quick to grow and an absolutely beautiful flavor. They remind me of Black Pearl King in the stem is tender and not as woody as other oyster mushrooms. Highly recommend picking This up. Still waiting on a second flush but I have full confidence this will be quite large aswell in terms of weight. Will definitely purchase again
