- Recognise when climate or diagnosis context is missing
- Use basic economics assumptions transparently
Course map
Every lesson opens with objectives and a diagram, carries sourced numbers, ends with a farm task and three questions.
- 01Button Mushroom FundamentalsIn button mushroom you grow the food for the fungus first and the fungus second. See why compost, casing and the room each exist, and every later decision makes sense.
- 02Production SystemsA bamboo shed in a Punjab winter and a panelled room in Tamil Nadu both grow button mushroom, but not the same way. Choosing a system you cannot run is the costliest early mistake.
- 03Compost FundamentalsCompost is not a recipe you copy. It is a living process you steer so that only the button mushroom can eat the result. Stop asking for a formula and start asking for a measurement.
- 04Phase IPhase I turns straw and manure into something hot, dark and alive. Growers lose yield here because they judge the heap by the calendar instead of by what it is doing.
- 05Phase IIPhase II is a few days that decide the whole crop. Too cool and the pests survive; too hot and you kill the microbes that finish the compost. Release it on evidence, never on the clock.
- 06Spawn & SpawningSpawning takes a few hours and decides whether the crop starts clean. The compost is cool, open and defenceless on that one day.
- 07Spawn RunFor about two weeks nothing shows from outside the bag and yet everything is being decided. This is the last stage where a room fault can still be fixed cheaply.
- 08CasingCasing is soil, and growers treat it like any soil. It is the one layer where the crop's worst diseases live and where every pin will form.
- 09Case RunAfter casing the crop disappears again for about a week. What you do with water in that week sets the size of the first flush, because once pins appear you cannot water freely.
- 10PinningThe crop does not decide to fruit. You do, on one day, by cooling the room and pushing the stale air out.
- 11Cropping & FlushesButton mushrooms come in waves called flushes, and the quiet days between waves are where growers lose money.
- 12Climate ManagementA thermometer near the door is not the crop's temperature. The bed, the sensor and the machine each carry a different number.
- 13WateringWater is the easiest thing to add to a mushroom bed and the hardest to take back.
- 14Crop HealthNaming a disease from one photograph is the fastest way to treat the wrong problem. The evidence is in the pattern.
- 15HarvestA mushroom picked an hour late is a different grade and a different price.
- 16Post-HarvestButton mushroom is mostly water and has no skin. What you earn is decided in the first two hours after picking.
- 17Farm HygieneDisease rarely walks into a mushroom farm alone. It is carried in on hands, tools, crates and old casing.
- 18Basic EconomicsMost mushroom budgets fail because they start from a price someone quoted on a phone call.
