The acceptable range is +20°.+25☌ or 68-77☏.Īt the lower temperature growth can slow down significantly. The main task for you for the first 2 weeks of fruiting period is maintaining proper fruiting conditions: ❇️ Optimum air temperature in the fruiting chamber is +21°.+23☌ or 70-74☏ Mycelium need time for adaptation, for switching mushroom "system" from colonization to fruiting. Also higher risks of contamination, because all molds like uncolonised top layer.įruiting parameters for Pinning or Primordia formationĪfter starting fruiting conditions for the first 5-7 days the mycelium seem like stalled and stop growing at all. If you start earlier it takes more time for pinning, hence fruiting. After that you can start to provide provide fruiting conditions (FC): fresh air exchange (FAE), misting, light.
Wait till the top layer of your mushroom cake will be colonised about 80-100%. All of them works great! When you should start fruiting conditions? That's why we use different types of fruiting chambers to make it easier: GrowBox, MonoTub, Bottle-Tek, shoeboxes, SGFC, Grow Tent etc. Therefore, grower should control fruiting conditions. 🔴 Pinning and mushroom development proceed if all these factors are in balance and coincide!Ĭhanging any of these factors can slow down or stop growing process at all. Although mycelium doesn't need the same light as plants, however photosensitive species require light for pin setting and normal mushroom metabolism This process creates proper microclimate, maintain high humidity and one of the triggers for pinhead initiation ✅ Evaporation from top layer of mushroom cake or block. ✅ High relative humidity is necessary for pin setting and normal fruit bodies development Usually, temperature drop is accompanied by rain in nature and humidity level increasing ✅ Lower temperature than optimal for colonisation period in incubator. ✅ Fresh air exchange (FAE) is a main trigger for mushroom fruiting indoor Most of mushroom species require a few basic fruiting conditions: Mushroom fruiting indoor response to the same conditions that trigger fruiting in the wild. As soon as tropical rains start again and temperature decrease these reserves are used for supporting mushroom fruit bodies development and releasing spores to start the new cycle again Basic principles of pin setting Unfavorable conditions is the best time to expand mycelium network, absorb nutrients and restore energy reserves. Mycelium wake up again when the humidity rises and temperature is suitable for fruiting.
Then mycelium goes dormant, continue creating mycelium network underground and wait for better times. The fruiting period is finished, when the season changed and climate conditions become too dry, too hot, or too cold. In tropical and subtropical climates mushrooms fruit during the rainy season, Psilocybe Cubensis particularly. In temperate and continental climates most mushrooms fruit during cool rainy spring and autumn. Pinhead initiation in nature depends on climate conditions and seasons of the year. Mushroom grower should understand the basic principles of pinning process and control changes. They are quite different from the conditions for mycelial growth. 🔴 Check out: Mycology Glossary & Mushroom Growing AbbreviationsĪll species require a set of conditions for pinning. Primordium (pl.primordia) - the initial fruiting body, the first recognizable but undifferentiated mass of hyphae that develops into a mushroom fruitbody. Pin, pinhead - a very young mushroom, so-named for the pin-sized developing cap. Hyphal knot - individual strands of hyphae bundle together and prepare to grow a fruit body Hypha, hyphae - individual cells of mycelium That's why it is the most important phase in mushroom cultivation each grower waiting for it Pinheads or primordia are knots of mycelium that proceed their development into small mushrooms. The change from the vegetative growth (mycelium growth or colonisation period) to the fruiting period (knots, pinheads and mushroom fruit bodies development) is called knotting, pinning, pin setting or pinhead initiation period. It lasts till there are enough nutrients for mycelium and mycelium wait for fruiting conditions. Then spores germinate and they have male and female spores! They literally create lovely pairs, connect and then form mycelium network. As you know mushrooms start their growth from spores after substrate inoculation.
