Line dry clothes outdoors. Crack a window open. Place houseplants outside. Use your kitchen exhaust fans.
What is the ideal humidity for a greenhouse?
The optimal relative humidity setpoint for most plants is around 80%. At this level, growth rates are highest for common greenhouse plants. At higher or lower humidity levels, plant physiological processes may slow down, leading to slower growth and lower quality output.
Can you put a dehumidifier in a greenhouse?
When choosing a dehumidifier for a green house you need to keep in mind air circulation and uniformity. If you put a single dehumidifier in a greenhouse with no ducting, the area around the dehumidifier will be dry. However the areas further away won’t be dried effectively.
Can a greenhouse be too humid?
Too much humidity in a greenhouse is trouble. Splashing from condensate dripping from the ceiling can spread diseases. Water puddles on the greenhouse floor promote algae growth, are insect breeding grounds, and a safety hazard for workers. Humidity that is too high interferes with plant transpiration.

A home should have a relative humidity of 30% to 60%. Above 60% and you have what’s considered “high” humidity. Besides being less comfortable, high humidity causes a host of other problems in your home, including: Growth of fungus and mold in various parts of the home.

Your cacti and succulents will be fine but the majority of plants are going to have leaf and flower problems.
Is 90% humidity too high for plants?
Most plants require about 60% humidity. Desert plants such as cacti and succulents will tolerate much lower humidity, around 30-35% but sometimes as low as 20%. Tropical plants require higher humidity, and those native to rain forests may need as much as 90% humidity.
Do you need a humidifier in a greenhouse?
When the humidity levels drop inside your greenhouse, photosynthesis slows down, and your plants can be susceptible to disease. Unless your plants are designed to withstand dry conditions you will need to buy a humidifier to maintain healthy levels.
Where should a dehumidifier be placed in a greenhouse?

Should I open my greenhouse during the day?
Open all doors and vents on sunny days. These can be left open at night if the temperature remains high. It is sometimes necessary to temporarily remove panes from glasshouses to assist ventilation in heat waves. Fit automatic vent openers to ensure roof vents open even when you are not around.
