“CONTROLLING YOUR TEMPERATURE
WILL ALSO HELP TO MANAGE MOISTURE
LEVELS AS HEAT DRIES UP MOISTURE.”
Humidity
Humidity levels should be maintained between 70 and 85 per cent.
When levels begin reaching 90 per cent and higher, growth slows,
fungal diseases start to occur, and early bolting becomes
a problem. Keep in mind it can be a challenge to measure
humidity levels when air is constantly circulating. Placing
multiple hygrometers around your greenhouse can help you
get a more accurate reading.
If humidity gets too high, you can add a dehumidifier to dry
it out. You might also try pruning your plants. Leaves perform
a process called transpiration in which they release moisture
into the air from pores on their surface, so reducing the
foliage should help reduce humidity levels. Proper ventilation
and air circulation are also important keys to managing
humidity levels in a greenhouse.

So, open doors or vents to reduce
humidity. Controlling your
temperature will also help to
manage moisture levels as heat dries up moisture.
If you live in an arid environment and need to increase
humidity, you can do this by spraying the floor with
water or installing a misting system.
Greenhouses can make a wonderful addition to your
garden as long as they are managed properly. When you
control your temperature, air circulation, and humidity,
you can take advantage of extended growing seasons
and eat fresh year-round.
