For the cultivation of our plants we use 100% rainwater that we collect via the greenhouse rooftops. This purified water is of perfect quality, and is vital for creating optimal growing conditions. Our plants are situated on a sealed foundation, so the water that misses the plants can be recollected and reused during the next sprinkling. This prevents water and nutritious substances from ending up in the stream. We have plenty of storage capacity for rainwater to ensure that we do not have to dip into 'other' precious water sources in the future.
