Grodan Improved Uni-Block

The Grodan Improved Uni-Block was designed as the ideal stacking block, giving you more choice in your growing configuration.

Developed specifically for larger plants, the new Uni-Block delivers the benefits of a Gro-Block as well as the advantages of the popular Uni-Slab:

  • Excellent water holding capacity
  • Higher substrate volume for extra root growth
  • Uniform WC and EC throughout the block
  • Improved control and steerability
  • Solid base for top-heavy plants
  • Larger yields

 

Leverage the benefits of products developed alongside plant scientists, that are specifically engineered to deliver real results for your crops. Grodan Gro-Blocks Improved with Advanced Wetting Technology — our improved stone wool substrate.

 

Real Science
Grodan partnered with the Wageningen University and Research facility in The Netherlands and top growers throughout North America to identify the optimal stone wool substrate and irrigation strategies for specialty crops. The result of months of scientific research and trials is Grodan Gro-Blocks Improved.

 

Real Results
The result of this scientific rigor is Grodan Gro-Blocks Improved with our Advanced Wetting Agent. In the scientific trials, plants grown in these Improved Gro-Blocks had faster rooting-in, higher yields, improved quality, and less water and nutrient usage throughout the entire crop cycle.

 

Real Improvement
These leading-edge blocks have the optimal fiber structure and physical properties for crop uniformity, more even Water Content (WC) and Electrical Conductivity (EC) distribution throughout the entire block, and the greatest steering capabilities available. Water distribution is more uniform throughout the entire block which is the basis for a well-defined root system with higher capacities for water and nutrient uptake to produce robust and vigorous crops.

  • Instructions

    Saturate
    1. Saturate Grodan Gro-Blocks in a nutrient solution of roughly 1.5 EC and 5.5 pH with a course spray or submerged in the solution for up to 2 minutes. Do not over saturate the blocks or leave soaking for extended periods of time.

     

    2. Measure wet weight
    Measure the weight of the block at saturation. Compare this weight to the weight of the blocks throughout the growing cycle. When the WC of the block is 55% to 65% apply the first irrigation.

    3. Transplant
    Insert the well rooted Grodan Starter Plug into the hole of the saturated Gro-Block

     

    4. Irrigation

    We recommend using a pressure compensated drip irrigation system.

    Grodan Improved GR-4 and Grodan Improved GR-10 Gro-Blocks  - insert 1 drip stake per block

    Grodan Improved Jumbo and Grodan Improved Hugo Gro-Blocks – insert 2 drip stakes per block.

    Volume of irrigation should be 3% to 6% of growing media volume (for example, Grodan Improved Hugo is 100 mL to 200 mL)

    Irrigation Volumes suggested flow rate is 0.5 gph (2 lph):
