Depending on the humidity needs of the mushrooms you're growing, Mella allows you to easily dial humidity up and down. The fresh air fan is also surprisingly quiet, creating a soft ambient background noise. And the water tank (which sits on the outside) lasts for 5-7 days, with a reusable washable filter that only needs to be cleaned between mushroom harvests.
-
While mushrooms don't need light for energy (like plants do), they do require light to form fruiting bodies. Dimmable built-in LED lamps allow you to place your Mella in rooms with minimal or no light, allowing you to create the optimal environment for your fungi. And, if you're not into night lights, they can easily be turned off at the end of the day.

How often should you clean your Mella?
The inner chamber, fan, and filter should be cleaned between fruitings.
IMPORTANT:
Before cleaning the chamber, always cover the humidity sensor with scotch tape. (The humidity sensor is in the circle with the cross in the right top of the Mella chamber.) This is critical, as isopropyl alcohol and some cleansers can damage the sensor.
To clean the chamber:
Wipe down the chamber with a soft cloth soaked in warm water and mild soap to remove spores. Then, spray chamber top to bottom with a 70% isopropyl alcohol solution. Wipe off immediately. Once dry, remove tape covering humidity sensor.
To clean the filter:
Rinse with warm water, then spray with 3% hydrogen peroxide. Let air dry.
To clean the fan:
Remove from chamber, then run under warm running water to remove spores. Let air dry.

Excellent Fruiting Chamber
We started our mushroom growing journey with our fruiting blocks on the kitchen counter as suggested. Since we enjoyed the process of watching them flower so much we decided on a whim to purchase this fruiting chamber and it did not disappoint. The chamber fits 4 blocks perfectly. Watching them grow inside the chamber makes the process even more fascinating. It regulates the blocks keeping them happy, hydrated and healthy. It's footprint is sleek and esthetically pleasing. Well worth the price tag. Definitely recommend.

Thanks, Kyle! We couldn’t do it without customers like you.

Makes growing so easy
I’ve been looking for something with a small footprint for my kitchen, and this looked interesting. Mella makes it so easy to grow mushrooms without all the spores and constant watering. My first flush was a breeze, and clean up was a breeze.
