Midwest Grow Kits Manure/Grass Lover's Bulk Spawn Growing & Casing Kit

Stop searching for the perfect blend for manure-loving mushroom varieties. The Manure/Grass Lover's Bulk Spawn Growing & Casing Kit provides every essential component you need, expertly formulated for cultivating specialty mushrooms that thrive on high pH casing and manure-based substrates. It's one of the most specialized mushroom grow kits available for advanced cultivators.

Designed and created by Gordo Tek, this kit is specifically formulated for growers cultivating grassland species. It features 6 pounds of premium substrate made with sun-aged horse manure, chopped straw, coir/vermiculite, and pH buffers. Each 3lb vacuum-sealed bag undergoes a rigorous 2.5-hour pasteurization in a hot water immersion bath, which skillfully eliminates harmful bacteria while preserving the beneficial microorganisms essential for a healthy grow.

The specialized casing layer includes a pre-measured mix of 2 quarts of peat moss, 2 quarts of vermiculite, and carefully balanced gypsum for optimal pH adjustment. It arrives in a 3T Large Unicorn Spawn Bag, ready for you to simply add water, mix, and sterilize. This comprehensive system from Midwest Grow Kits ensures you have the precise environment needed for a successful harvest. For larger projects, consider the Complete XL Specialty Grass Lover's Kit.

FAQs

What types of mushrooms is this kit best for?+

This kit is specifically formulated for dung or grassland-loving mushroom species that require a manure-based substrate and a high pH casing layer for optimal growth.

Is this kit suitable for beginners?+

This kit is designed with advanced growers in mind due to the specific requirements of the species it targets. However, the included step-by-step guide makes the process clear and manageable for dedicated learners.

What do I need to provide myself?+

You will need to supply your own mushroom spores or liquid culture, as they are not included in the kit. You will also need a pressure cooker or steam bath to sterilize the casing mix.

Why is the substrate pasteurized instead of sterilized?+

Pasteurization uses a lower heat treatment (a 2.5-hour hot water bath) to kill harmful contaminants while preserving beneficial microorganisms in the manure substrate. These microbes can help protect your mycelium from competing molds.

How is this different from a standard monotub kit?+

While a standard kit like the 44Q Monotub Kit uses a coir-based substrate for a wide range of species, this kit uses a specialized, nutrient-rich manure substrate and a high-pH casing layer specifically for grassland varieties.

What should I do after harvesting my mushrooms?+

To properly preserve your harvest, we recommend drying them thoroughly. A dedicated tool like the MycoLabs Mushroom Dehydrator ensures optimal results and longevity.
