Cultilene PC cube Stone Wool Hydroponics Growing Medium

Stone wool cubes provide a neutral solid basis to get the most out of your crop by optimizing the root environment and root activity.
Water uptake, air content, pH, electrical conductivity and nutrient uptake, the crucial parameters for hydroponics agriculture are taken into consideration during the manufacturing process.
The water buffer growing substrate is easy to control and delivers a constant supply of enriched water to the plant rhizosphere to maximize micronutrient and macronutrient uptake capacity for ideal rooting patterns and vegetative and generative growth, a steering range for your crop at every developmental stage.
Designed to enable large scale water savings, lower energy bills, less nutrient usage through water and fertilizer reuse to strive for a world without raw material depletion and without waste, reduce the amount of crop protection products used and higher yields per square metre.
Helps food production by increasing quality and quantity of crops while decreasing costs and inputs.

• For hydroponics propagation, potting up, cultivation of vegetables, herbs, fruits and  floriculture.
• Fibre structure with a lower density providing less resistance for easier rooting.
  
• Firm, solid cube can be used for the cultivation of all plant species.
• Rapid rooting from plug to cube.
• Place plug into cube holes and place cube on top of slabs for efficient sequential potting up, eliminating transplant shock.
• The cube is provided with plug and planting holes and grooves.
• The target level for moisture content is between 50%and 90% of the volume.
• Initial wetting to completely saturate the cubes before use is needed. Wet in an ebb and flow system or by watering with overhead sprinklers before sowing seeds or transplanting seedlings.
• Make sure that the grooves under the cube are placed perpendicular to the gutter heading to the water source.
• Use within two years of the delivery date.
