Rockwool for growing plants – Slab 100 x 15 cm
“Slab” stone wool panels are available for growing vegetables and flowers. The differences between the panels are minimal – both in terms of strength, moisture content and dimensions. In addition, the durability of these boards puts them in a class of their own.
The plate method is most often used by commercial farmers to grow larger plants with high productivity (tomatoes or cucumbers) and large-scale flower production. Drip irrigation is the best method for feeding plants at regular intervals.
◦ Board with faster response to water content with good EC control
◦ Excellent responsiveness to changing growth circumstances
◦ Very even distribution of water and EC
These panels are supplied in clearly labeled UV resistant biodegradable polyethylene sleeves.
Poly sleeves have several functions:
◦ Comfort in handling.
◦ Prevention of algae growth.
◦ Preventing roots and diseases from easily moving from plate to plate.
◦ Reduction of evaporation.
◦ Allowing panels to be fully saturated before use.
◦ Control/direction of water runoff from slabs.
Rockwool bad (mineral wool or stone wool) has a high water retention capacity and contains a lot of air. Rockwool bad is also light, compact and relatively cheap. Therefore, they are the most commonly used growing medium in horticulture. However, it is not easy to grow on Rockwool, some knowledge is required. Rockwool bad itself has a high pH, so it is important to water it well with a low pH (5.1 to 5.5). Make sure the pH in the plate is not less than 5.0. This prevents the wool from collapsing and losing its elasticity. Stone wool lasts a very long time if it is well treated.
◦ Slab plates are an excellent choice for growing in Aqua Trays.
◦ Length 1 meter to accommodate 1 meter long water trays
◦ Rockwool – a traditional and trusted growing medium
◦ Several plants (3-6) can be grown in one plate.
◦ Multiple panels can be used side by side to cover almost any area
◦ Often used for “stadium” layouts.
◦ A very popular cultivation method favored by the Dutch
◦ Can be used in a recirculation system or waste disposal
How the slab works:
Rockwool panels are designed to be used in an Aqua Tray of the appropriate size. Contains plenty of water and air for rapid rooting and growth. More plants can be grown on the length of the plate (usually 3-6), which reduces the supply and discharge pipes. Aqua trays work by containing a small number of plants (usually between 3 and 6) spaced evenly along a stone wool sheet placed inside. At regular intervals, the nutrient solution is pumped into the plants via drippers, and the excess nutrient solution drains from the stone wool plates. One of the advantages of using bad plates is that they take up little height and several can be used side by side on a table or on a frame for a “stadium” setup.
Use of panels:
Slab boards are typically used in Aqua trays and can be placed side by side on a table or frame. Ideally, the height should decrease slightly towards the end of the drain pipe. The Rockwool panels in the Aqua trays can also be placed in a shallow “V” shape so that the trays on the sides are at a higher level than those in the middle. This way, the plants in the trays on the sides are as close to your lamp as those directly below it, increasing your light efficiency. Place a rockwool pad of the appropriate size in the water tray and place the drippers near the places where you will place your plants. Connect the drippers to your nutrient solution tank via a pump and timer, plant your cuttings and you’re ready to start growing!
