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

How to use lava gravel in your soil mix
Lava Gravel can be a wonderful additive to your soil mix. It enhances drainage, which is benefical to help reduce overwatering or root rot.
Due to its higher pH levels, it can also be added to your soil mix to increase the alkalinity of the soil.

Lava gravel as a fertilizer
You can boost your soil's nutrients by mixing lava gravel and worm castings.
Worm castings contain mycorrhiza, which is a naturally occurring fungi. This fungus works in harmony with the plant roots.
It helps to extract minerals from the soil and share them with the plant. This makes water and nutrient stress much less likely.
And, in return, the fungi receives sugars from the roots.

Lava gravel has a lot of the minerals that mycorrhiza love! By combining these two components, you optimize this exchange.
You don’t need much gravel; 10 to 50 grams per 10L of soil is enough.
