Basic growing-house structure
1. Arched growing house: a freestanding frame without walls, covered with plastic film and straw mats.
2. Lean-to growing house: an east–west structure with four earthen walls, bamboo supports and a film cover.
3. Winter-warm-style house: build three or four earthen walls, 0.5–1 m thick, on an east–west axis, with one or two rows of posts and firmly tied supports forming a slight arch for sunlight.
4. Winter-warm greenhouse: similar to a solar vegetable greenhouse, it may remain above 10°C in winter and suit medium-temperature and specialty mushrooms. The archived article cites a higher investment, around RMB 6,000 at that time, as a limit to adoption.
Growing-house temperature control
Growing-house temperature varies seasonally and daily with outside temperature and the sun's position, generally higher by day and lower at night. Management should reflect the season and time of day.
For seasonal temperature changes, first adjust roof-cover thickness. Add insulation as temperatures fall, using film and straw-mat layers. Below −13°C, the article suggests temporary stove heating, with straw mats opened at midday for sunlight.
Minimize day-to-night temperature variation and keep the house relatively stable, adapting control to the season and variety.
Growing-house humidity control
Manage humidity by spraying the air, floor, substrate walls or beds, racks and surrounding walls; keeping the floor moist; and using water-holding trenches along house edges or substrate stacks to stabilize humidity.
Air management
The original article gives an approximate CO₂ target of 0.05% and an upper limit of 0.1%, with a stated ambient level of 0.03%. At its target level, it describes the house as having only a faint mushroom smell and no stuffy feeling.
Light management
Depending on season and variety, generally maintain 500–1,000 lux inside the house. Reduce to 200–300 lux for varieties whose quality is affected by stronger light.
