(expt.) LB Mushroom Flake Soil – 1 Gallon Bag (128 oz)

LB Mushroom Flake Soil is a substrate currently under experimental development, designed specifically for rhino/flower beetle larvae.
Its concept is based on recreating Type A flake soil made by the famous Japanese Dynastes hercules breeder HirokA.

In his 2009 blog post, HirokA mentioned that his substrate was made from 100% oak waste-mycelium, enriched with protein, carbohydrates, and calcium.
Unfortunately, he never disclosed the exact ingredients or ratios of those additives.

Because of this, I have been gradually adjusting the formula each month, starting from the original LB Flake Soil ratio of 70% pellet : 30% waste-mycelium, then moving to 60:40, 50:50, and now in November, I am testing 40:60 (60% waste-mycelium).

As the percentage of waste-mycelium increases, the substrate becomes more moist and requires more frequent mixing.
The additional proteins and carbohydrates also cause strong fermentation heat and ammonia odor, so creating a stable and reliable substrate using 100% waste-mycelium will likely require at least six more months of experimentation.

Since this flake soil is still in the testing phase, the ratio of waste-mycelium and additives will change with each batch.
However, I will always check the fermentation temperature and pH, and I will test every batch on my own rhinoceros beetle larvae first.
Only batches that perform safely and properly will be sold, so you can use them with confidence.

Thank you for your interest, and I will continue working hard to create an even better substrate.
