For mushroom growers

From flush to clamshell, per pound, honestly.

Gourmet mushrooms run on flushes: substrate blocks colonize, fruit in waves, and a week's harvest of oysters and lion's mane goes out in clamshells to the market and by the pound to chefs. The grow room hums around the clock and every block has a cost. MadeKeeper divides the room's real numbers across the pounds it actually fruits.

How MadeKeeper maps to your grow room

Blocks as the batchA dozen blocks log with their substrate and spawn cost; each flush's harvest divides those dollars across the pounds picked. Second flushes make the same blocks cheaper per pound — visibly.
The room's hum, countedHumidifiers, fans, and lights run all week. The grow room's power logs into each week's harvest, so per-pound cost includes the electricity bill's share.
Clamshells for the market, pounds for the chefMarket clamshells at $6 and chef orders at $12 a pound run as separate channels — retail's packaging against wholesale's volume, both honest.
Contamination in the mathThe block that greened over logs as the loss it is. Real yield per block is the number your spawn order and your prices both stand on.

One week's flush, to the penny

Say 12 blocks flush 38 lb of oysters:

  • Substrate and spawn, 12 blocks @ $2.60$31.20
  • Grow-room power for the week$6.50
  • Clamshells and labels, 38 @ 41¢$15.58
Week's cost — $1.40 a pound$53.28

At $12 a pound across market and chef orders, the week grosses $456.00 and keeps $402.72 — and when a batch of blocks contaminates, the same math shows exactly what the loss cost, which beats mourning it vaguely.

Cultivated mushrooms sell like produce in most states — foraged wild ones are a different program entirely, often with certification requirements. MadeKeeper keeps your harvest and sales records clean per channel; which side of that line your table sits on stays yours to check.

Straight about what's live

Materials and true cost per piece, products (in bulk or one-of-a-kind), sales that drain stock, the was-this-fair-worth-it event math, mileage, expenses, and the year-end tax packet — all in the app today. Etsy and Square sync, your own storefront, a booth card reader, and shipping labels are building, shaped with founding makers. Nothing above describes a feature that doesn't exist without saying so.

Questions mushroom growers ask

How do second flushes change the cost?

The block's cost is already paid, so second-flush pounds carry only the week's room costs and packaging — the cheapest mushrooms you'll ever pick. The ledger shows it plainly, which is the argument for patience before the compost pile.

What about selling to restaurants?

Chef orders run as a wholesale channel — steady pounds, no clamshells, no table fee. Most growers find the chef list is the backbone and the market is the marketing; your split will show in a month of records.

How do I handle contaminated blocks?

Log them as losses when they green over. Your real yield per dozen blocks — not the catalog's promise — becomes the number that sets prices and sizes the next substrate run.
