Choosing Your Bulk Setup
Exotic and bulk growing is about method and scale. Every system here is designed to work with a wide range of cultures — you bring the genetics, the kit does the rest. Here's how the options compare:
Monotub kits (best for bulk yields)
The monotub is the go-to for hands-off bulk fruiting. Available in 28Q, 44Q, and 66Q sizes, plus fully automated MycoClimate versions that manage temperature and fresh air for you. Add a refill kit to run the tub again without starting over.
Jar-style (PF Tek) kits
Our classic jar grow kits use the time-tested PF Tek method — simple, compact, and a great way to learn the fundamentals before scaling up.
All-in-one bags
Sterilized all-in-one bags are the simplest bulk-ready format — inoculate, colonize, and fruit in one bag. A solid bridge between small grows and full monotubs.
Build your own from bulk substrate
Prefer to assemble your own system? Start with bulk substrate, casing mixes, and grain, and scale exactly how you want.
Not sure where to start? A 44Q monotub kit is the sweet spot — big enough for a satisfying bulk yield, small enough to manage in a spare room or closet.
Exotic & Bulk Growing FAQs
What is an exotic or bulk mushroom grow kit?
It's a system built for larger, more advanced grows than a single all-in-one bag — monotubs, PF Tek jars, and bulk substrate setups. These kits are designed to work with a wide range of cultures, so you choose the genetics and the kit provides the growing environment.
What's the difference between a monotub and a PF Tek kit?
A monotub is a bulk fruiting chamber that uses grain spawn mixed into a large volume of substrate for bigger harvests. PF Tek is a jar-based method that's simpler and more compact — ideal for learning the process or growing on a small scale.
Which setup should I choose?
Newer growers often start with a jar kit or an all-in-one bag to learn the fundamentals, then move up to a monotub for volume. If you want the biggest hands-off yields, go straight to a 44Q or 66Q monotub — or an automated MycoClimate kit for climate control on autopilot.
Do these kits include genetics or spawn?
It varies by product. Some complete kits include grain spawn and substrate; others are equipment-only so you can pair them with your own cultures. Each product page lists exactly what's in the box.
Can I reuse the equipment?
Yes. Monotubs and fruiting chambers are built to run cycle after cycle. Just add a refill kit — grain spawn plus bulk substrate — to start a fresh grow without buying the whole system again.
