Same process. New strain optional.
Step 01
Drop in the block
Open your ShroomBag box. Place the new 5lb colonized block inside.
Step 02
Cut & mist
We don't mark a spot. Make one cut, 4 to 5 inches long, anywhere on the front. Mist twice a day.
Step 03
Harvest in ~14 days
Twist and pull at the base. Expand outdoors when the block is ready to keep fruiting.
