Why Choose This Pack
The Oyster 5-Pack is built for oyster enthusiasts who want to grow the full spectrum of what the Pleurotus genus has to offer. At $55 — saving $7.50 over individual pricing — you get five distinct species with different colors, flavors, textures, and fruiting temperature ranges, letting you grow oysters year-round by matching species to seasonal conditions. Pearl and Blue thrive in cooler months, Pink and Golden love warmth, and King Oyster is a premium specialty that produces thick, sliceable stems. This pack is perfect for growers who already know they love oysters and want to explore the full family.
Usage Instructions
- Sanitize your work area, tools, and contact surfaces before handling.
- Prepare grain, substrate, agar, or grow kits according to your standard operating procedures.
- Introduce the liquid culture using sterile or near-sterile technique (e.g., in front of a flow hood or still-air box when applicable).
- Maintain species-appropriate incubation and fruiting conditions for temperature, humidity, and fresh air exchange.
Shelf Life & Storage
Store refrigerated at 34–39°F (1–4°C) away from direct sunlight. Under proper storage, typical shelf life is 3–6 months unopened. Always visually inspect for contamination, damage, or off-odors before use.
Quality & COA
Each batch is prepared using standardized procedures and test-inoculated on appropriate media before release. These internal checks act as our in-house Certificate of Analysis (COA) to confirm viability and cleanliness at the time of packaging.
How to Use This Bundle
- Start with the liquid culture — inject 1-2cc into the grain bag through the self-healing injection port.
- Incubate the grain bag at 70-75°F until fully colonized (2-4 weeks).
- Mix colonized grain with substrate at a 1:3 ratio in a monotub or grow bag.
- Wait for full colonization, then introduce fruiting conditions (fresh air, 80-90% humidity).
Tip: Follow the included product guides for each component. The bundle is designed to take you from spore to harvest in one workflow.

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.
