The ShitMaster MINI™ is a premium 1.5 lb all-in-one mushroom grow bag engineered for controlled, small-batch cultivation. Designed as part of the established ShitMaster™ Grow Bag Series, this compact system delivers consistent performance in a simplified format.

Built with a manure-based, grain-free substrate blend, this bag supports strong colonization while helping reduce contamination pressure commonly associated with grain-heavy grow bags.

Fully hydrated. Fully sterilized. Injection-ready.

Why Choose the ShitMaster MINI™

Unlike generic mass-produced grow bags, the ShitMaster MINI™ is backed by years of documented builds and real-world cultivation use across Fullsend Organicks platforms.

This 1.5 lb all-in-one mushroom grow bag is ideal for:

• Beginner growers wanting a low-risk start

• Genetic trial runs
• Micro-batch production

Compact size. Proven substrate profile. Documented performance.

Premium Manure-Based, Grain-Free Substrate

Most all-in-one mushroom grow bags rely heavily on grain.

The ShitMaster MINI™ uses a manure-based, grain-free substrate profile designed to deliver stability, efficiency, and simplified cultivation. The result is a streamlined grow process without unnecessary prep work or substrate transfers.

Designed for reliability from inoculation through fruiting.

How It Works

5. Fruit directly in the bag or transfer to a fruiting chamber.

Simple process. Clean execution. Consistent results.
