I'll be sticking with soyhulls for now.
Balancing cost and quality in mushroom cultivation: why cheaper isn't always better.
In mycology, saving money isn’t always straightforward. While I’ve managed to cut some production costs by buying materials in bulk, finding soyhull pellets in Reno remains a challenge. Even online, shipped soyhulls are still over $1 per pound. In contrast, I can get oak pellets for half the price, despite high shipping costs.
I’ve explored potential substitutes for soyhull pellets, like beet pulp and alfalfa, both of which would cost about $0.35 per pound—a promising savings. But there’s a tradeoff.
For example, using beet pulp, it costs around $1.85 in materials to produce mushrooms, compared to $2.70 with soyhulls—a 31% savings per substrate bag. But this doesn’t tell the whole story. Soyhull pellets are highly productive, yielding up to 1.5 lbs of mushrooms in the first flush. With beet pulp, I’ve seen yields closer to 1.1 lbs.
Reducing my cost per substrate by 31% has also reduced productivity by 27%. After creating a matrix to compare per-capsule costs based on yield per bag, I found that the practical savings, after accounting for productivity loss, is only about 4%. So, is it worth the compromise?
For me, the answer is no. Here’s why:
I want to grow the best mushrooms possible. It’s fulfilling to produce large, healthy fruits with strong yields.
Each substrate unit requires one plastic bag. Lower yields per substrate mean I need more bags, increasing waste—a factor that’s often overlooked in cost calculations.
For now, I’ll keep searching for a soyhull pellet supplier in Reno to bring down costs. It’s not worth sacrificing quality and sustainability for a slight savings. If a substitute can someday match soyhulls in productivity at a lower cost, I’ll be ready to make the switch.
