One of the most important indicators after air temperature that every gardener should take into account is air humidity.
Especially if we are talking about a greenhouse, if it rained on a hot summer day and if the summer resident does not have a hygrometer. But how in this case can you determine the air humidity?
The answer to this question is given by AiF.by.
How to determine air humidity
The easiest way is to enter the greenhouse and take a breath.
If you feel the same as in a bathhouse – it’s hard and difficult to breathe, then this means that the microclimate in the greenhouse is not good.
What to do in this case
The first thing you need to do is create a draft in the greenhouse, which is done by opening the doors and vents or lifting the film from below.
If you water the plants, the air humidity will only increase.
Why is this important?
High humidity in the greenhouse will affect fruiting.
Because of this, pollination will not occur, as the pollen in the flowers will get wet.
Along with humidity, pests and fungal diseases such as late blight may appear.
But if you can create a draft, the situation can be brought under control.
