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.

Strong flushes and easy to use, solid choice.
first time ever trying this and ngl I didn’t think it would work lol. took a bit to see anything but once the bag turned white I was like ohhh it’s happening. ended up with about an ounce dried sooo happy with it.
Easy to manage, colonized steady and fruited nicely. Already on my second flush and the mushrooms look strong.
wasn’t expecting much but wow it delivered. mushrooms looked healthy, easy af to set up, and I actually got more than I thought. loveee this.
This was the perfect intro for me. The first two weeks felt slow but once I saw the white spreading I knew it was working. Fruiting brought in around 1.2 ounces and I was thrilled to actually make it work.
