When it comes to the perfect greenhouse temperature in winter, the needs of many plants during the dormant period are very different from those in the summer months. Carrying out regular checks of the most important climate data in the warm house is particularly important during this time.
It must not be too cold or too warm in the greenhouse in winter
The right plant temperature in winter is less a matter of discretion for the hobby gardener, but mainly depends on the species-appropriate comfort temperature of the plants. The different heat and light requirements of certain species outside their vegetation period must also be taken into account. For larger warm houses with multiple types of plants, installing a precisely adjustable heating system can easily become a tricky challenge.
Plant welfare does not come for free
If you run your plant breeding professionally, you should never save on the heating system. What is meant is not primarily the dimensioning of the heat supply, but rather its control mechanisms Temperature sensors, thermostats and other tools. If only the potted plants from the field are to overwinter in the warm house, the installation will certainly be less extensive than is the case with a 20 square meter collection of orchids or succulents.
Consider growth factors for temperature in winter
This also includes the light intensity and the carbon dioxide content of the indoor air, with which the well-known paradox according to which the temperatures in poor lighting conditions are to be reduced in the interests of healthy plant growth. Controlling all of this safely and having it under control even during the winter is not just a question of technology. That includes a lot gardening skills with a portion of experience - just the best thing about the hobby of plant breeding.
tips
When occupying a warm house in winter, a greenhouse temperature that is too high can do more harm than good. Therefore, the most important readings for temperature and humidity should be recorded at least three times a day. Not only in different places around the interior, but also on or in the floor.
