Quick Takeaway
For a quick answer, check the main steps below. Always ensure proper sanitation and optimal temperatures for the best yield.
Scaling Up: The 100 Bag Run
Let's look at a realistic scenario for a micro-farm producing 100 bags (10-lb blocks) of Oyster mushrooms per week.
The Costs (Estimates)
- Substrate (Master's Mix): 500 lbs dry = ~$150
- Bags: 100 filter patch bags = ~$40
- Spawn: 10 lbs of grain spawn (if purchased) = ~$100
- Utilities & Overhead: ~$50
- Total Production Cost: $340
The Yield & Revenue
A well-managed 10-lb block should yield at least 2 lbs of fresh mushrooms on its first flush.
- Total Yield: 200 lbs
- Wholesale Price: $8/lb
- Total Revenue: $1,600
The Profit
Gross Profit = $1,600 - $340 = $1,260 per week.
