FeaturesThe kit includes 10 seedling planting kits and 2 planting tools, each with 12 trellises, for a total of 120 nets. Each kit includes a clear plastic cover, a plug, a test piece and a flat piece. It is easy to start indoor seedlings of various plants. With a transparent plastic cover, it is very suitable for watching the germination of seeds and the progress of growth. At the same time, the transparent cover allows light to pass through, but it can retain moisture. Adjustable vents allow you to easily control humidity as your seeds germinate and grow. Once you notice that the seeds are germinating, open the vents and let some moisture out, as too much moisture can cause the plants to squash. There are drainage holes at the bottom of each plug tray. When you continue to add water to the soil as needed, the soil will retain moisture but not get wet. The seed setting kit can be reused and recommended for tomatoes, melons, pumpkins, cucumbers, and for planting larger seeds of flowers, herbs, and other vegetable seedlings.
