Want to colonize and fruit mushrooms up to 8x faster than traditional grains?

Our five pound Super Grow Bags were formulated in our labs using all natural ingredients to excelerate colonization times. You’ll be amazed at how much faster you can get your mycelium from bag to tub.
You can also let your mushies fruit right inside the bag. We always recommend fruiting in our monotubs for larger yields, but if you just want fast, open up the bag and let ’em grow!
