Intermediate Growing Supplies
You're past the starter kits — ready to work from live cultures, spawn your own grain, and run bulk substrate. Here's the gear to scale up, step by step.
Liquid Cultures
Expand any strain from a live culture
- Includes20+ LC syringes
- Best forInoculating grain
- StrainsGourmet & functional
Live liquid culture is the intermediate grower's genetics workhorse — inject it into sterile grain and you're colonizing in days. We carry 20+ strains, from workhorse oysters and lion's mane to reishi, cordyceps, and a few novelties.
Grain & Bulk Substrate
The spawn-to-bulk chain
- IncludesGrain, coir, Master's Mix
- Best forGrain → bulk runs
- CasingManure & coir
The heart of intermediate growing: inoculate sterile grain with your culture, then spawn it into bulk substrate. Grab pre-sterilized 5-grain or rye bags, plus coir, Master's Mix, and manure-based casing to build tubs at scale.
Gourmet Grow Kits
Ready-to-fruit blocks & kits
- Includes5 lb blocks, kits
- Best forFruiting now
- SpeciesTurkey Tail, Cordyceps +
Want a harvest without the substrate work? Fully colonized 5 lb gourmet blocks and complete Cordyceps kits fruit straight out of the box — a fast way to add new species to your rotation while you scale the rest.
Monotubs & Automation
Dial in your fruiting chamber
- IncludesTub upgrades, MycoClimate
- Best forConsistent fruiting
- Sizes44Q & 66Q
Take the guesswork out of fruiting. Convert a 4 lb all-in-one into a tub, or add MycoClimate automation to a 44Q/66Q monotub to control humidity and fresh air hands-free for even, repeatable flushes.
Sterilizing & Sealing
Prep your own grain & bags
- IncludesSterilizer, sealer, bags
- Best forMaking your own spawn
- Key tool23Qt Presto
Ready to prep your own substrate and grain? A Presto pressure sterilizer and impulse heat sealer let you sterilize and seal filter-patch bags at home — the gear that moves you from buying spawn to making it.
Pre-Poured Agar Plates
Your first step into agar
- IncludesMEA & Rapid Rhizo
- Best forCleaning up cultures
- Ready-to-useNo pouring
Agar without the lab setup. Pre-poured, ready-to-use plates let you clean up a culture, isolate a strain, or check for contamination before you commit grain — the natural bridge toward advanced lab work.
