• Excellent control: Thanks to better initial saturation, improved water distribution and enhanced water holding capabilities, Grodan Gro-Block Improved makes it even easier to control your crop, from propagation through to harvest, using even less water and fewer nutrients.
• Balanced steering: Thanks to advanced technology and uniformity, WC and EC can be adjusted more rapidly and efficiently for very good vegetative and generative steering.
• Faster rooting-in: Trials have repeatedly shown that the initial rooting-in phase occurs several days faster, speeding up the vegetative phase and time to harvest.
• Stronger, more vigorous plant development: Because the roots make better use of the entire substrate volume, the uptake of water and nutrients is improved, resulting in larger plant size, greater stem thickness and bigger leaves.
• Optimised wool structure: Grodan Improved Gro-Block maintains its structure, firmness and rigidity throughout the entire growing process.

Grodan Improved Gro-Block is a direct upgrade of the existing Delta products and will be available in all existing dimensions. Thanks to easier control and steering combined with stronger and healthier plants, Grodan Improved Gro-Block will help growers at all levels of experience to achieve higher yields of uniform plants with a consistent quality profile.

In addition to the Gro-Block Improved, Grodan also offers a premium range of Grodan Max products featuring Vision 1.0 Technology. This unique top-of-the-line range has been specifically developed for more experienced, large-scale growers who are looking for a best-in-class product offering maximum steerability.
