Description
Plagron Seedbox for an organised and controlled start from seed
The Plagron Seedbox is a complete propagation kit designed for germinating up to 12 seeds. It includes a growing tray with a transparent lid, 12 peat germination plugs and 250 ml of Plagron Seedbooster. This gives you the main components required for the germination stage in one coordinated set. It is suitable for beginners looking for a straightforward way to start seeds as well as experienced growers who want to raise several seedlings under comparable conditions.
Managing moisture and temperature during germination
For the initial preparation, Plagron recommends mixing 125 ml of Seedbooster with 125 ml of water and distributing the solution evenly over the plugs. Once they have absorbed the liquid, any excess solution is poured away. The seeds are then planted approximately 5 mm deep before the transparent lid is fitted to close the growing tray. The manufacturer recommends an ambient temperature of 20–24 °C during the germination stage.
Ventilation and light once seedlings emerge
According to Plagron, seeds may begin to germinate after approximately 4–7 days under suitable conditions. Once seedlings start to emerge, the transparent lid is positioned slightly askew on the tray. This creates small openings that allow fresh air to reach the young plants. Sufficient light should also be provided so that the new shoots can develop steadily. Additional equipment for this stage can be found among the plant propagation supplies.
Moving young plants on from the germination plugs
When the seedlings grow high enough to reach the lid, it can be removed completely. Once roots begin to grow outside the germination plugs, the young plants are ready to continue in a suitable growing medium. One option for this next stage is Plagron Seeding & Cutting Soil, which is intended for sensitive seedlings and young plants. Plagron recommends adding the remaining 125 ml of Seedbooster to the nutrient solution used for the first watering after transplanting. Further complete solutions for propagation can be found with the propagation and cutting kits.
