4lb Mushroom Grow Kit

More Control. Bigger Yields. Same Clean Start.

You've done a grow or two. Now you want more control over the process, and bigger harvests to show for it.

The 4 LB Kit separates the grain from the substrate, giving you the flexibility that all-in-one bags can't match.

What's Inside:
• 1 lb sterilized grain bag with self-healing injection port
• 3 lb dung-loving CVG substrate (OMRI-listed ingredients)
• 0.2-micron filter patches on both bags
• Complete growing guide

Why Separate Bags?
Timing matters. With separate grain and substrate, you spawn at the perfect moment, when colonization is 100% complete. The result? Stronger mycelium. Faster colonization. More consistent flushes.

All-in-one bags force you to work on their schedule. This kit puts you in control.

Three Ways to Grow:
1. Spawn to a monotub for maximum yields
2. Use shoeboxes for smaller, faster batches
3. Fruit directly in the substrate bag (simplest setup)

Same Lab-Grade Quality:
15 PSI sterilization for 3 hours. Vacuum-sealed fresh. Made in the USA with OMRI-listed substrate ingredients. The cleanest possible start for your grow.

What to Expect:
• Up to 42oz of fresh mushrooms
• Up to 3 flushes
• Works with all mushroom varieties
• Perfect monotub refill size

Perfect For:
Intermediate growers ready to level up. Or anyone who wants more control over spawn timing without mixing their own substrate.

Ships in plain, unmarked packaging. Just add spores.
