The humidity tent, is a polyethylene bag with pre-punched holes that fits right over Mushroom Shack Mushroom Farm. The holes provide air circulation while the plastic bag keeps the block moist and humid. Support the bag with skewers, chopsticks, or any other fastening method you desire. You can mist your Mushroom Farm by placing a sprayer nozzle right through the holes. If the holes aren’t large enough for your sprayer nozzle, you may need to cut a larger hole in the bag.
