By order of the company HZPC the living lab has re-boosted its large germ cell and started using it on 1-2-2019. Potato plants are rooted in this climate cell on 17-layer LED carts. The first results are extremely satisfactory and will therefore be repeated in order to get the production for the company up to standard. After rooting, the plants will be hardened off in a specially prepared section of the experimental garden.
