Quick Buy
Grodan / Cultilene trays are the global standard in hydroponic gardening. They offer a completely sterile and inert environment, essential for the health of young plants at their earliest stage.
Product Advantages
Rockwool, made from molten basalt rock, provides a unique fiber structure that holds water while leaving plenty of air pockets for the roots to breathe.
Why choose this substrate?
- 🔹 Rapid Rooting: Stimulates powerful development of root hairs.
- 🔹 Two Variations: Choose 77 cells for larger seedlings or 150 cells for maximum efficiency.
- 🔹 Easy Transplantation: Cubes are easily moved without the risk of root damage.
Preparation and Usage
For optimal results, always soak the tray in a pH-adjusted solution (5.5 - 5.8) before use. This prepares the rockwool for the needs of young plants and prevents pH shock.
Note!
Please select the desired number of blocks (77 or 150) from the options before ordering.
Who it’s for
The Grodan / Cultilene Tray is an essential tool for professional growers, breeders, and hydroponic enthusiasts. It is designed for those who refuse to compromise on plant health from day one. Perfect for anyone starting a large number of seeds or working with delicate cuttings (clones) that require a sterile, controlled environment.
Key features
Sterile Rooting: Provides a pathogen-free environment, minimizing the risk of diseases in young roots.
Capillary Efficiency: The rockwool structure distributes water and nutrients evenly to every single cube.
Optimal Aeration: A balanced Air-to-Water ratio ensures that roots never suffocate and always have access to oxygen.
Unique differentiators
Dual Variation: Choose between 77 larger cells (for a stronger start) or 150 smaller cells (for maximum productivity in limited space).
Inert Medium: The mineral wool does not affect the chemical composition of your nutrients, giving you 100% control over feeding.
Uniformity: Every block has identical density, leading to synchronized development across the entire tray.
Why this product
By choosing this tray, you are investing in security and high yield. It eliminates the mess of transplanting and ensures a powerful, well-developed root system before moving to the primary growth system. It is the most reliable way to shorten vegetative time and increase your success rate in cloning and germination.
FAQ
What is the difference between the 77 and 150 cell trays? The difference is the density and size of the plugs. The 77-cell version offers larger cubes (35x35 mm), while the 150-cell version (25x25 mm) is optimized for maximum space saving.
Do the cubes need to be soaked before use? Yes. Rockwool is naturally alkaline. Soaking in a solution with pH 5.5 – 5.8 for a few hours neutralizes the alkalinity and prepares the medium for the plants.
