Product information

The Spongepot offers an easy way to germinate your seeds with little risk of complications. It consists of a culture medium with different types of peat and cocos bonded by an organic glue which gives it a spongy feeling.

One of the great advantages of the spongepot is that the seed does not have to be touched unnecessarily, thus avoiding stress and possible damage to the fragile taproot. Used in combination with a propagator, optimal moisture climate is easily achieved.

  • 100% biological
  • Rapid germination
  • Optimal moisture balance
  • Ideal in combination with soil
  • Bacto mixture included

Bacto gives every medium a boost of useful micro-organisms. Selected strains of streptomyces bacteria and trichoderma fungi are stimulated by a natural catalyst called Myconate. The combined working will enhance the health of your plants and the fertility of the soil.


What you need:

  • Spongepots
  • Seeds
  • Measuring cup and water
  • Propagator and perlite or likewise product
  • Screwdriver or similar item, slightly wider than the seeds
  • Tie-wrap/binder or tape, to mark the depth of the hole on the screwdriver

1. To start with you need one litre water with a temperature of around 25 °C. Add the Bacto mixture and mix well.

2. Place the Spongepots on a layer of perlite in a propagator. Irrigate the Spongepots and the perlite with the Bacto mixture. Make sure the layer of Perlite contains a small reservoir of water which is not near the surface of the Perlite. Otherwise the Spongepots may absorb too much water which is not beneficial for the seedling.

Using Bacto will provide an optimal balance between water and air in the Spongepot. By keeping the layer of Perlite sufficiently moist, the Spongepot will be moist as well. It also keeps the humidity high in the propagator. Check the Spongepots now and again to see if the fluid level in the Perlite is high enough.

3. Make holes of approximately 5 to 10 mm deep in the Spongepots. A handy tool can be created by marking the correct distance on a screwdriver with a tie-wrap or piece of tape. Now pierce the Spongepot until the marker touches the surface of the Spongepot, and every hole will be of the correct depth.

4. The last step will be to insert one seed in every Spongepot. To make sure the seeds will be at the right depth you can use the same tool as for piercing the holes. Which side of the seed is up does not matter. The seedling will find its way to the surface while the root will grow in the other direction.

Most seeds need a few days to one week to germinate. Try to be patient during this period and do not open the Spongepot to peek inside.

First the root will appear and soon after the germ will follow. The seedpod will fall off on its own. Removing the seedpod manually can damage the seedlings first 'leaves', which it needs very hard as food supply in the first days.
