❄️ Winter (Dec - Feb)

The dormant season outdoors, but the busiest season indoors.

  • Indoor Spawn Prep Start creating your grain spawn and sawdust blocks indoors. You need fully colonized blocks ready for Spring.
  • Site Selection Scout your garden for shady, moist spots. Clear debris.

🌱 Spring (Mar - May)

The planting season. As soon as the frost is gone.

  • Inoculate Beds Break up your colonized indoor blocks and mix them into wood chip beds outdoors.
  • Mulching Cover the fresh spawn with a layer of cardboard and fresh chips to protect it from drying out.

☀️ Summer (Jun - Aug)

The survival season. Heat is the enemy.

  • Watering Water your beds deeply once a week during droughts. Keep the mycelium alive.
  • Inspection Check for pests (slugs) or competing molds.

🍂 Autumn (Sep - Nov)

The harvest season! Temps drop, rains come, mushrooms pop.

  • Harvesting Check beds daily. Wood lovers (Cyanescens) fruit when temps hit 50°F (10°C).
  • Spore Printing Take prints from your best outdoor fruits to save genetics for next year.
  • Feeding Add a fresh layer of wood chips before winter to give the colony food for next year.

🏠 Indoor Growing: Seasonal Adjustments

Indoor cultivation is season-independent for light and humidity, but your ambient room temperature changes across the year, requiring seasonal tuning:

  • Winter (Dec-Feb) Rooms may drop below 18°C overnight. Add a thermostatically controlled heat mat under substrate or a space heater on a temperature controller. Cold drafts near windows can crack substrate surface.
  • Spring (Mar-May) Ideal natural temperatures in many homes — often the easiest time for indoor grows. Watch for increased airborne mould spore counts (windows opened more often).
  • Summer (Jun-Aug) The most challenging indoor season. Ambient temperatures above 27°C cause heat stress and dramatically increase contamination. Use a clip fan to circulate air, avoid south-facing rooms, or consider a small air conditioner or grow in an air-conditioned room.
  • Autumn (Sep-Nov) Second-best season for indoor growing as temperatures stabilise. An excellent time to start a new grain-to-bulk project.

📊 Species Fruiting Season Reference

Different psilocybin species have dramatically different seasonal windows. Use this table to plan your outdoor bed inoculations:

Species Inoculate Beds Fruiting Season Temperature Trigger
P. cyanescens March-April October-December Below 10°C nights
P. azurescens March-April October-January Below 7°C nights
P. ovoideocystidiata Feb-March or August April-May and Sep-Nov Seasonal temperature shift
P. semilanceata Foraging only (UK grassland) September-November First frosts, wet conditions
P. cubensis (indoor) Year-round Year-round Controlled environment

📋 Full Year Task Planner

A practical month-by-month checklist for growers who cultivate both indoors and outdoors simultaneously:

  • January: Order spore prints/syringes for the new season. Inoculate grain jars for indoor spring grows. Scout outdoor bed locations while ground is clear.
  • February-March: Begin colonising sawdust blocks for spring outdoor inoculation. Prepare outdoor bed sites — dig, add fresh hardwood chips, allow to settle.
  • April-May: Transfer colonised spawn to outdoor beds before temperatures rise. Begin fruiting indoor cubensis grows. P. ovoideocystidiata spring flush begins.
  • June-August: Focus on indoor grows with climate control. Water outdoor beds weekly. Spore-print outdoor fruits if any appear.
  • September: Begin daily temperature monitoring of outdoor beds. Reduce indoor fruiting temperatures to mimic autumn drop.
  • October-November: Peak outdoor fruiting season. Check beds every 1-2 days. Harvest before veil breaks. Add a fresh layer of chips after each flush.
  • December: Take spore prints from best autumn specimens. Plan next season's genetics. Begin planning indoor winter grow cycle.
