We chose to make GUS in a low-fire ceramic for its natural breathability, ability to maintain moisture and regulate temperature. Mycelium, commonly thought of as the root system, is the primary part of the fungi organism. Our design is focussed on keeping the mycelium within GUS, cool and cozy.

GUS is designed to grow specialty mushroom varieties that are easy to care for, with light misting a few times a day for best results. Mushrooms grow rapidly and can be harvested in a matter of days after they begin to take shape as pins or primordia (mycology speak for baby mushrooms).

GUS's convenient nesting design maximizes countertop space. Collect multiple GUS to build a vertical mushroom farm and grow a variety of mushrooms at once. GUS stacks are very sturdy. We recommend stacking up to 3 high.

Each GUS vessel holds a mushroom grow block (fruiting block) which can be ordered online or with a little DIY spirit, created at home. We recommend using a 5lb size grow block (sold separately).

GUS's design is modular and supports growing for both for top fruiting and side fruiting mushrooms. Why is this important? While some mushrooms such as many oyster varieties will thrive growing in either direction, others have a preference. Top fruiting lids will be available as an additional accessory in 2024.

We will be launching additional lid accessories that allow for top fruiting with unique shaped openings suited for a range of top-fruiting mushrooms. The base GUS planter comes with a primary lid that acts as a cover when GUS is being used for side fruiting.
