The PlantPlugs of the Experimental Set are - same as in our PlantPlug Sets - the perfect nutrient medium for your plants: The substrate cones contain all the vital nutrients for your herbs, flowers or fruits to germinate, grow and thrive.

Our PlantPlugs are made of coconut fibres, a by-product of the coconut industry. They maintain their shape when in contact with water. Because they emit almost no particles, they are very clean to handle.  

To keep your plants well nourished, the PlantPlugs are enriched with a mineral fertiliser containing an excellent supply of nutrients. Of course, the PlantPlugs are 100% biodegradable and free from pesticides, fungicides, insecticides, genetically modified organisms, or otherwise questionable substances.



How to use:
Put seeds of your chosen plant into the PlantPlugs and insert the PlantPlugs into the GreenBox. Watch your plant grow!

For even faster growth, we recommend the new GreenBox Booster.

Product details

The contents of our Experimental Set, on the other hand, consist of 24 dimensionally stable plant substrates without seeds. You have the opportunity to give free rein to your creativity and experiment with different types of seeds.

A PlantPlug consists of mineral fertiliser wrapped in coconut fibre, which is a by-product of the coconut industry. When a PlantPlug comes into contact with water, it retains its shape and is thus an ideal mediator of liquid and nutrients for the plant. The plant substrates we currently source from the Netherlands are 100% biodegradable and free from pesticides, fungicides, insecticides and other foreign substances. Our BerlinGreen seeds come from Germany and Poland.

Before the plant substrates make their way to us, they are thermally treated. This ensures a long shelf life and the exclusion of foreign bodies such as insects. To keep them for a long time at home, store them at room temperature in a dry place away from light. Simply keep the PlantPlugs in the package that came with them and you can enjoy them for up to 3 years.

Any more questions?

You can grow different types of plants at the same time! Some plants grow slower, others faster. We have already put together plants with similar growth rhythms in our PlantPlug sets.

Our PlantPlugs consist mainly of coconut fibre, a by-product of the coconut industry. A mineral fertiliser that provides the plants with good nutrients is also included. Of course, they are 100% biodegradable and free of pesticides, fungicides, insecticides, genetically modified organisms or otherwise hazardous substances.

The optimal storage for the PlantPlugs: dry, dark and at room temperature. Stored this way, they will last for at least 2 years.

Of course! We also offer PlantPlugs without seeds. With the 24 PlantPlugs of the Experimental Set, you can experiment with the seeds of your choice. You may also plant individually selected seeds in your GreenBox. These are available in our seed selection in both single and 4-packs.

As the plant grows, its roots penetrate the PlantPlug more and more, so that in the end they can no longer be separated from it. To provide space and nutrients for the roots of a new plant, you should use a new PlantPlug for a new sowing.

In many cases you can harvest several times: If you only cut off the outer leaves of lettuce and leave the inside, it will continue to grow. With herbs, it is best to cut off the upper shoots, which are located above the leaf branches. This way, new shoots can grow.

Absolutely! The GreenBox also provides optimal starting conditions for larger plants. As soon as the "nursery" becomes too small for them, you can repot them in normal soil (indoors or outdoors). This way you can also use the GreenBox as a perfect growing station for your (vegetable) garden. With the PlantPlugs as a growing base, the whole process is clean and easy.

To prevent algae or mould from forming on the moist and light shining surface of the PlantPlugs, we have developed the U-plates. These are placed on the substrate surface after sowing. Seeds and seedlings still get enough light.

The U-plates should be left in place until the plant has formed enough leaves to overshadow the surface on its own. Then the U-plates can be removed.
