Are slabs with a high capillary action capacity too wet for winter cultivation?
No, since the moisture content of a slab is determined by the evaporation and the watering. Not using trickle irrigation and allowing extreme transpiration in the plant (hot pipes) will automatically lead to the slab drying out. In other words: the moisture content in the slab is controllable. In principle, we strive for a lower moisture content in the winter. We can achieve this by allowing the crop to transpire sufficiently (minimum pipe temperature, fast ventilation) and through holding long pauses in between the watering sessions.
