Day 55-60. Grow Tent preparation and Fruiting ConditionsSpoiler: You don't actually need a Grow Tent to grow Reishi 😉First, I assembled my grow tent and placed a metal shelf rack inside.DIY Ventilation with HEPANext, I built a ventilation with a HEPA filter.Then, I installed it on top of the tent.This setup filters air through the HEPA filter (installed in white connector) and pulls air in. The incoming air also creates positive pressure inside the tent, which helps to reduce the risk of airborne contaminants.Pro Tip: This method is much better for mushroom cultivation than setups where air is blown out of the tent, as those often draw in dirty air through gaps in the tent (especially from the floor).DIY HumidifierAfter that, I built a humidifier using affordable items: a plastic food container, a PC fan, a simple fogger, a water float valve, some pipes and connectors and big water bottle (8 Qts/Liters).The humidifier (a plastic box inside the tent) is connected to a large 8-liter water tank placed outside the grow tent.Water from the large tank flows down and automatically fills the humidifier to the correct level, regulated by a float valve.I only need to refill the big tank once a week and it's super convenient!The fogger creates fine mist. The fan pushes mist through the pipe and helps spread it evenly throughout the tent.I ran a few tests to make sure everything was working properly, and the grow tent was finally ready for the fruiting stage!Fruiting Conditions for the next several weeksTemperature: it's hot season righ now and temperature in my fruiting chamber fluctuates between 74°–81°F (23–27°C). Sometimes reaching 82°–86°F (28°-30°C) if I turn off the AC.Ventilation: 2–4 times per day. I run the system for 15–20 minutes each time. Ganoderma is highly tolerant to CO2, which is a great plus!Humidity: 80–85%. I run the humidifier 2–4 times per day together with the ventilation, then let it continue for another 5–10 minutes. Total run time is around 20–30 minutes per cycle.Light: 2–4 hours per day (cold white LED).Note: I’m currently using only a thermometer and hygrometer as sensors. There’s no automation in my setup yet.
