P³ ALL-IN-ONE BAG
Grow manure-loving mushrooms right in the bag—minimal gear, maximum payoff.
WHY P³
Formulated by working mushroom growers, P³ streamlines the whole run from inoculation to harvest inside a single sterile bag. No juggling tubs, no fuss—just clean, consistent performance for fast colonization and hefty canopies.
WHAT’S INSIDE
A proprietary blend of sterilized, nutrient-dense, organic manure-based compost, organic grain, coco coir, and targeted supplements. Optimized hydration and structure create a stable, well-aerated environment that mycelium tears through.
BUILT-IN ADVANTAGE
-
Self-healing injection port for use with a spore or culture syringe
-
5-micron filter patch to block contaminants while allowing steady gas exchange
-
Dialed water activity for vigorous colonization and reliable pinsets
Note: injection-port color may vary.
STERILE. VERIFIED.
Bags are steam-sterilized in commercial autoclaves. We validate every cycle with biological indicators and onboard temperature sensors. Slight condensation around the port can happen—that’s normal and won’t affect performance.
HOW YOU CAN RUN IT
P³ is designed as a self-contained chamber for simple, clean grows. Want tighter environmental control? Drop your colonized bag into your preferred fruiting setup (e.g., a monotub or tent) to fine-tune airflow, humidity, and CO₂.
SPORES VS. LIQUID CULTURE — READ THIS
P³ plays nicely with both. Liquid culture contains live mycelium and typically shows activity sooner. Spore solutions first need to germinate, which can add extra time before you see visible growth. Choose what fits your timeline and workflow.
Heads-up: Always follow the laws in your area and the best practices for your species. Bruise Blue supplies sterile substrates and gear—what you choose to grow is on you.

Bruise Blue Substrates make Canopies
Our subs are built for canopy runs—nutrient-dense, truly sterile, and tuned for the texture and moisture your mycelium wants to rip through. Pair them with clean, fully colonized grain at a solid spawn ratio (think 1:2–1:4), mix evenly, and you’ll set the stage for fast colonization, tight knotting, and wall-to-wall pinsets. The structure holds moisture without going soggy, so fruits develop thick and even under proper FAE and humidity. Do your part on cleanliness and environment; Sour subs handle the rest—flat, full canopies that make tubs look like fields.
Organic Grains | Better Runs
Because they’re clean, consistent, and built to colonize fast. Our organic grain bags start with responsibly sourced organic grain, hydrated for optimal moisture and pressure-sterilized in-bag for a true blank slate. The kernel size and texture are dialed to maximize surface area (read: more inoculation points, faster run times) without turning mushy or clumpy. Each bag ships with a filter patch and self-healing injection port, lot-tracked and QC-checked so you know exactly what you’re working with. Result: aggressive, even colonization, fewer headaches, and reliable performance at scale—exactly what “best” should feel like in a grow room.
FAQs

What makes Bruise Blue different?
Best prices, true bulk options, fast ship times, and clean, lab-sterilized product. No fluff—just stuff that performs. This is a mushroom company made by mushroom growers. We hope that it shows in our product.
Why Isn't there free shipping?
Because “free” isn’t free. Most sellers bake shipping into higher product prices. We don’t. At Bruise Blue, you pay exactly what it costs us to get your order to you—no markups, no “handling” fluff, no BS. That keeps our bags priced as low as possible and your shipping transparent. We pass through real carrier rates (and our discounts) and combine items to save where we can. Need a freight quote for pallets? Reach out and we’ll price it straight.
What are your shipping times?
Orders usually leave in 1–2 business days. Bulk and pallet orders may need a short lead time—ask if you’re on a deadline.
What if my order arrives damaged or looks off?
We'll replace it.
Do you ship discretely?
Plain boxes, simple labeling. We ship to the address you provide—please ensure deliveries are permitted in your area.
