3. Postavljanje i priprema
3.1. Hydration and pH Adjustment
Rockwool has a naturally high pH. Prior to use, it is essential to pre-soak the cubes in a pH-adjusted water solution to create an optimal environment for plant growth.
- Prepare a nutrient solution or plain water with a pH level between 5.5 and 6.0. Use a reliable pH meter for accurate measurement.
- Submerge the rockwool cubes completely in the pH-adjusted solution for a minimum of 1 hour, or until they are fully saturated.
- Carefully remove the cubes from the solution and allow any excess water to drain naturally. Do not squeeze the cubes, as this can damage their internal structure and reduce essential aeration.
3.2. Plasman
Place the hydrated cubes into your chosen growing tray, propagation dome, or hydroponic system. Ensure that the cubes are stable and positioned to allow for adequate drainage.
4. Uputstvo za upotrebu
4.1. Seed Starting
- Gently place one or two seeds into the pre-drilled hole of each rockwool cube.
- If desired, lightly cover the seeds with a small amount of rockwool fiber from the cube itself or a thin layer of vermiculite.
- Maintain consistent moisture levels within the cubes and provide the appropriate temperature range for the specific seeds you are germinating.
4.2. Rooting Cuttings
- Prepare your plant cuttings according to standard horticultural practices, ensuring a clean cut and removal of lower leaves.
- Insert the base of the cutting into the pre-drilled hole of the rockwool cube. Ensure there is good contact between the cutting and the rockwool medium.
- Provide a high humidity environment (e.g., using a propagation dome) and indirect light to encourage successful rooting.
4.3. Watering and Nutrient Management
Once seeds have germinated or cuttings have rooted, begin feeding with a diluted nutrient solution formulated for the plant's current growth stage.
- Monitor moisture levels daily. Rockwool should remain moist but never waterlogged. Allowing for slight drying between watering cycles can promote stronger root development.
- Regularly check and adjust the pH of your nutrient solution to maintain optimal nutrient absorption by the plants. A typical range for most plants in rockwool is 5.5-6.5.
5. Održavanje
5.1. Transplanting
When plant roots begin to emerge visibly from the sides or bottom of the rockwool cube, it indicates that the plant is ready for transplanting.
The Grodan Rockwool Grow Cube can be directly placed into a larger rockwool block, integrated into another hydroponic system, or transferred to a traditional growing medium such as soil or coco coir.
5.2. Cube Reusability
While rockwool can technically be reused, it is generally recommended for single-use applications to prevent the potential transmission of plant diseases and to ensure consistent, optimal performance. If reuse is considered, thorough cleaning and sterilization of the cubes are necessary.
6. Rješavanje uobičajenih problema
6.1. Slow Germination or Rooting
- Mogući uzroci: Incorrect temperature, insufficient or excessive moisture, poor seed viability, or improper cutting preparation.
- rješenja: Verify that environmental conditions (temperature, humidity) are appropriate for the specific plant. Ensure cubes are consistently moist but not saturated. Use fresh, viable seeds or healthy, properly prepared cuttings.
6.2. Algae Growth on Cubes
- Mogući uzroci: Excessive light exposure on the rockwool surface, high humidity, or nutrient solution splashing.
- rješenja: Cover exposed rockwool surfaces with a light-blocking material (e.g., plastic film, perlite). Reduce humidity if it is excessively high. Ensure proper watering techniques to minimize splashing. While algae is generally harmless to plants, it can indicate conditions favorable for certain pests.
6.3. Nutrient Deficiencies or Excesses
- Mogući uzroci: Incorrect pH of the nutrient solution, improper nutrient concentration, or inadequate drainage leading to salt buildup.
- rješenja: Regularly check and adjust the pH of your nutrient solution. Ensure the nutrient solution is mixed according to manufacturer recommendations. Confirm proper drainage to prevent the accumulation of salts in the cubes.
