To get the best growth, we recommend pairing your fruiting blocks with a growing system like the BoomRoom, a monotub, or a Mella fruiting chamber to create the optimal growing environment for your mushrooms.

The average fruiting block will produce between 1-2 lbs per flush (less in subsequent fruitings). And depending on the species, you can expect 1-3 fruiting cycles per block. Note that some of the more advanced species are harder to get subsequent fruitings.

Yes! Fruiting blocks are mushroom grow kits. But, unlike our boxed countertop Spray & Grow kits, these are larger and grow in bags. Our fruiting block kits are made from vigorous edible mushroom mycelium grown on a proprietary blend of hydrated and sterilized hardwood sawdust with other organic amendments that mushrooms love! Just follow the directions specified for each species (in the instruction book provided) and watch your mushrooms grow!

We want every grow to be a success! The team at North Spore will select kits with the highest chance of optimal growth based on the time of year, so you’ll be sure to have an abundance of fresh edible mushrooms for your next meal. Plus, our ability to focus on making large numbers of select species each month means we can pass along the savings to you.
