Verified Buyer
The millet grain from Fungi Substrate is by far the best I’ve used. It arrives perfectly hydrated and completely sterile, with zero contamination issues. My mycelium colonized fast and evenly!
— Megan R.
Verified Buyer
These grow bags are super durable and seal perfectly. The filter patch provides great airflow, and I’ve had 100% success with colonization. Definitely my go-to for bulk grows!

This CVG mix is the perfect balance of moisture and nutrients. My mushrooms fruited faster and healthier compared to other brands. Great quality!
— Lisa K.
Verified Buyer
These stir bars are perfect for liquid cultures! They spin smoothly and don’t stick, making my LC prep super easy. A must-have for serious cultivators!
