Growing successfully in GRODAN

Five tips for successful growing on GRODAN: 

  1. As a general rule, you will not need to water the newly transplanted GRODAN Delta block or plug for the first few days
  2. Always use pH adjusted water with plant food.
  3. Never let the GRODAN go bone dry.
  4. No light : No water—the plants are resting.
  5. Make sure that the slab or block can drain freely - avoiding situations where the stone wool is sitting in water.
