Socially responsible production

At Sybotanica we not only want to make plants happy, but people happy as well. In our production team we exclusively hire people with a distance from the workforce, and help them rehabilitate to the normal working life.


Take Peter for example:

Peter has been with Sybotanica since the 1st hour, and has now been promoted to head of production & a permanent contract! Where he was the first employee, he now manages a team of 3 production workers.

What makes this achievement even more impressive is that Peter achieved all this with only 10% visibility! 🕶️ With a few minor adjustments to his working environment, Peter is able to perform his job 100%.

Peter has now been through two moves and knows all the ins & outs of Sybotanica. He can even feel by the potting soil which variety it is. That's quite a challenge with 16 different mixes!

We are confident that Peter will keep production running smoothly in the coming years too! 💪

FAQ

Why does the pumice come slightly moist?
Pumice has a natural moisture content. The moisture is necessary for good plant growth with this material.
If the pumice is completely dry, it will no longer absorb water and can draw moisture from your plant's roots.

How do I use pumice to prevent Fungus Gnats?
You can add a thin layer of pumice to your soil as a top dressing to prevent fungus gnats and other soil-borne bugs.
Fungus gnats lay their eggs in the topsoil. A layer of pumice blocks their path, so they cannot reach the soil and lay eggs!

What is the difference between pumice and perlite for houseplants?
The main difference between pumice and perlite is that pumice is much heavier. It also holds onto more moisture and nutrients than perlite.
It is better for mixes that need weight and good drainage, like cacti and succulent mixes.

Why THIS Pumice compared to others?

Very clean, compared to regular pumice which has other vulcanic stones and grains.

Origin of our Pumice

Pumice comes from Germany at the Volcanic Eifel. Only a small portion of the vulcano is mined at a time. After that, the empty area is restored with clean soil left over from other building projects. Then native trees & plants are planted back at the mining location to let the wildlife restore.

It’s in Germany, close to The Netherlands. This makes the supply chain very short. The pumice is washed, but the water is re-used up to 100 times before being replaced. All in all a pretty great choice.
