Mushroom Grow Kit - 4 Pack - All In One Mushroom Grow Bags
Quick and Discreet Delivery

I'm giving 5-stars based on speedy, discreet delivery. Unfortunately, I let the area get too hot and (I think) I killed the mycelium.

It’s Legit

My kit showed up sooner than I thought, everything was packed perfectly, to the point that damage suffered by the the box during transport had no effect on the contents in sign. Inoculated my grain with no contam issues and everythings running smoothly. Absolutely gonna be buying from these guys again 👌🏼

MonoTub Mushroom Grow Kit

The other reviews are not exaggerating! Within 4 days after inoculating I saw mycelium growth. About 1.5 weeks after inoculating I broke and shook up one bag. Then another bag the next day. About three days later I broke up the last two. Definitely sped up colonization! Within a couple days of the break and shake I could see rapid new growth. Very happy so far. Ordered a couple more to start up different strains!

Consistency Everytime - We ensure the grain and substrate are separated to facilitate easy monitoring and faster colonization. This is unlike many large suppliers, who mix the grain and substrate to create a homogeneous mixture.
Sealed Before Sterilizing - Through our proprietary process, we seal the bags before sterilization to ensure no contamination. Shelf-stable food products are made the same way, which guarantees product integrity.
Meticulous Attention To Detail - We hand-fill every bag, carefully packing the ingredients and neatly folding the bag to prevent premature mixing. We place these in a perfect-size box and protective liner bag for further protection.
Highest Quality Ingredients - We source local organic ingredients from trusted USA businesses, prioritizing freshness and quality. These are carefully prepared in-house to ensure consistency, purity, flavor, and nutritional value in every batch.
A Superior Result - We use temperature probes to carefully monitor the core bag temperature during sterilization to achieve and maintain the precise time and temperature targets needed for for consistent quality, safety, and reliability in every batch.
