About The Product
Each 4lb kit bag produces 2–3 flushes and yields around 1–2 dry ounces of mushrooms.
Start Your Cultivation Journey
Step into the fascinating world of mushroom cultivation with Grow&Flow’s 4lb all-inclusive grow kit. Designed for both first-time growers and seasoned hobbyists, this kit takes the guesswork out of the process, allowing you to experience the full mushroom life cycle right from home — no additional tools or materials required.
Engineered for Stronger, Smarter Growth
This kit features a two-stage design that separates 1 lb of sterilized grain from 3 lbs of nutrient-rich CVG substrate (Coco Coir, Vermiculite, Gypsum). The grain bag includes a secure injection port for clean inoculation, while the substrate provides ideal moisture retention and aeration. The result? Faster colonization, improved yields, and a streamlined grow.
A Substrate Blend That Delivers
Our substrate is carefully formulated to support vigorous growth and healthy fruiting. Coco coir retains moisture, vermiculite creates airflow and structure, and gypsum supplies essential minerals to strengthen mycelium. Together, this balanced blend promotes lush, reliable flushes.
Flexible Fruiting, Minimal Setup
Whether you prefer to fruit your mushrooms in a monotub or directly in the included grow bag, this kit gives you the flexibility to choose. Each bag is fitted with a 5-micron filter patch to ensure proper gas exchange while maintaining a sterile environment. Step-by-step instructions are included to guide you from inoculation to harvest with confidence.

Growing mushrooms with my own hands turned out to be a great experience. Really thankful for how simple this kit made it.
Flushes came in strong and it was simple to use. Really solid kit overall.
This was my first time trying and I honestly didn’t think it would work. It took a little while before I saw signs of growth, but once the bag turned white I knew it was working. Ended up drying about an ounce and was really happy with it.
Easy to manage, colonized steady and fruited nicely. Already on my second flush and the mushrooms look strong.
I wasn’t expecting much but it really delivered. Mushrooms came out healthy, the kit was easy to set up, and I ended up with more than I thought I would.
