The conditions in the cultivation greenhouse play a key role in whether the developing young plants produce good yields at harvest time. The maintenance effort is limited, growing your own is fun and you even save a lot of money compared to purchased plants.
What is a cultivation greenhouse for and what should you take into account?
A propagation greenhouse is ideal for growing your own young plants from seeds to guarantee a he althy harvest. Factors such as sufficient moisture, appropriate temperature and light intensity are crucial to achieve optimal growth.
Gardening is a very natural hobby that also helps you to provide yourself with naturally he althy fruit and vegetables almost all year round. A propagation greenhouse is almost indispensable for this, especially if you want to grow your own young plants from seeds. To ensure that the home garden turns into a blooming landscape with the first rays of spring sunshine, the gardening season begins with cultivation in the greenhousein the first two months of the year
Growing greenhouse in many sizes from mini to XXL
The range of prefabricated houses that garden retailers offer for growers of young plants ranges from plastic baskets with lids for window sills to mobile shelves with glass roofs for outside. Particularly creative hobby gardeners also use discarded glass cabinets from their old kitchen furniture for cultivation or put together a greenhouse themselves with a few leftover materials. The size depends solely on the need for fresh fruit and vegetables, everything elsejust needs to be practical
Basic equipment: potting soil, house and seeds
Empty curd cups or halved milk cartons are basically enough to start your first steps as a young plant breeder. If you still have little gardening experience, you can get potting soil (€6.00 at Amazon) from a gardening store. Otherwise, a mixture of compost, topsoil and a little sand is the ideal breeding ground for growing your own young plants from seeds you have grown yourself or purchased.
What should go into the propagation greenhouse first?
Kohlrabi, cucumbers and tomatoes as well as radishes, peppers and lettuce can be sown at the end of January. If you don't want everything to be ready to harvest at the same time, we recommend sowing in several small quantities with breaks of one to two weeks. Most failures with home-grown plants occur when the seeds that sprout after a few days are watered too abundantly. Depending on the location, it is sufficient to mist the plants and the soilusing a used spray bottlemoderatelywithout puddles forming in the soil. As a small guide for the optimal sowing times, a short summary:

So that cultivation in the greenhouse runs optimally
- When sowing, the potting soil should bewell moistened but never completely soaked, as the seedlings rot quite quickly at the roots.
- The seedlings grow best at 18 to 24°C. They don't like going to the sauna during the blazing midday sun at all.
- Until the first leaves become visible, the propagation greenhouse shouldnot be exposed to excessive light intensity, otherwise they will grow too quickly without being able to form a stable stem.
Tip
Better safe than sorry, does not apply when growing young plants from seeds. This means that if one seed is intended per plant, there does not have to be three. Otherwise, you should prick out after one or two weeks at the latest to remove the excess seedlings.
