Midwest Grow Kits Fresh Air Amplifier Fan Unit For Ecosphere Greenhouse Systems
Are your gourmet mushrooms struggling to reach their full size potential despite perfect humidity and temperature?
The Fresh Air Amplifier Fan Unit is specifically designed to solve the oxygen limitation problem in Ecosphere Greenhouse Systems, dramatically increasing fresh air circulation for improved yields.
Essential for cultivators growing oxygen-demanding varieties like oyster, Li
on's mane, and other gourmet mushrooms that require significantly more air exchange than standard passive filter disks can provide.
While the standard round adhesive filter disks included with Ecosphere systems allow for passive air exchange sufficient for many varieties, gourmet mushrooms often require substantially more oxygen to achieve optimal growth. This purpose-built amplifier unit actively draws fresh oxygen into your tent, enabling your mushrooms to grow larger and more quickly with less energy expenditure.
The system features a high-power 4" fan with brushless motor that can completely refresh the air inside your Ecosphere within minutes. The adjustable speed dial allows precise control over airflow rates to match the specific requirements of different mushroom varieties, while the reusable and washable 6"×4" filter vent ensures no contaminants enter your growing environment.
Installation is straightforward with pre-installed double-sided adhesive and comprehensive instructions, making this essential upgrade quick to implement for any Ecosphere owner seeking to maximize their growing potential.
