Blue Oyster All-in-One Grow Kit — Pre-Inoculated & Ready
Skip the syringe entirely. This All-in-One bag comes pre-inoculated with Blue Oyster (Pleurotus ostreatus var. columbinus) liquid culture — sterilized grain and substrate are already in one bag and colonizing when it arrives. Just wait for full colonization, then introduce fruiting conditions. Blue Oyster is fast-growing, prolific, and one of the most forgiving species for beginners. Everything you need in a single bag.
Specifications
- Species: Blue Oyster (Pleurotus ostreatus var. columbinus)
- Contents: Sterilized grain + substrate in one bag
- Status: Pre-inoculated — colonizing on arrival
- Time to harvest: 3-6 weeks (depending on colonization stage at arrival)
How to Use
- Keep bag at species-appropriate temperature (65-75°F) until fully colonized.
- Once grain is fully white and colonized, mix grain into substrate layer.
- Cut an X in the bag and introduce fruiting conditions (humidity, fresh air, light).
- Mist daily and harvest when caps begin to flatten.
Storage
Keep at room temperature (65-75°F) and allow to colonize. Fruit as soon as fully colonized for best results. Do not refrigerate.
Quality & COA
Each kit is inoculated under sterile conditions in our clean facility. Batches are test-inoculated and verified for viability before release.
How to Use This All-in-One Grow Bag
- Sterilize the injection port with an alcohol prep pad.
- Inject 1-2cc of liquid culture through the self-healing injection port, aiming for the grain layer.
- Incubate at 70-75°F until the grain layer is fully colonized with white mycelium (2-4 weeks).
- Mix the colonized grain into the substrate layer by gently massaging and kneading the bag.
- Wait for full colonization — the entire bag should be covered in white mycelium.
- Introduce fruiting conditions — open the bag, mist daily, and provide fresh air exchange.
Tip: The all-in-one bag is designed to simplify the growing process — grain and substrate are in the same bag, reducing contamination risk and transfer steps.
What's in the Box

If this is your first grow, we recommend starting with a All-in-One Grow Bag or a Ready-to-Fruit Block — both are designed for beginners and require minimal equipment. For liquid culture use, you'll also need a grain spawn bag and a substrate bag. Check out our growing guides for step-by-step instructions.
