Growing crops is and remains a natural process. We are of course subservient to the laws of nature, although we consider it a challenge to continually bend them or stretch them out. Every grower has its own customs, methods and often even trade secrets.
For an optimum growing result, the slabs must be positioned on a flat surface that has a slight fall, to allow them to drain rapidly and easily
Drain holes
Well functioning drain holes are of the greatest importance, as the excess water must be able to drain from the slab. Therefore, pay considerable attention when making the holes.
-Make the drain holes prior to planting;
-The best position for the drain holes: between the plants and at the lowest point of the slab;
-The vertical drain holes must be at least 3 cm long. Horizontal drain holes (for rose cultivation) must be 10 – 15 cm long and be repeated every 50 – 60 cm. Fray the sides of the holes somewhat, so that they cannot easily clog up.
When the blocks are positioned on the slabs, for the first few days they must be watered frequently to speed up the growth of the roots into the slab.
As soon as the roots have developed well into the slab, the water supply can be adjusted.
From this stage adhere to the following rules:
-Regularly check the volume of water being drained;
-Start watering when evaporation has started. Stop watering at least 2 hours before sunset. On dark days even earlier. The time to stop is among other things dependent on the weather, the crop and the chosen watering strategy;
-Whether additional water is needed in the evening or night depends on the circumstances. However, it is recommended if the slab dries out too much during the night;
During the dark period, the EC will increase due to the accumulation of nutrients. Try to avoid this by flushing these nutrients from the slab by supplying more water during the hottest period of the day, possibly with a lower EC.
Higher water content:
-Less water each time, higher frequency;
-Higher watering frequency;
-Start earlier;
-Stop later;
-Watering at night.
