The annual Grotop Master Dry is the solution for the gardener who wants to be able to generatively control the growth of his crop through water management in order to harvest top quality products. Thanks to the wide control range, he can adjust the water content to the needs of the season. The range is between fifty and eighty percent (daily level). The steerable and dry nature of the mat make it easy to steer the crop generatively during rooting and plant development.

• Wide control range
• Efficient EC replacement with less drain
• Generative crop response

The Grotop Master Dry also has a high irrigation efficiency. After administering a new nutrient solution, almost ninety percent of the present nutrient solution is displaced. The drain water therefore consists almost entirely of "old" nutrient water. In this way, maximum EC replacement can be achieved with minimal watering. 　

The two-layer structure of the Grotop Master Dry, with a dense top layer and a porous bottom layer, guarantees a balanced WG/EC and root distribution. The coarse fiber allows the mat to drain well. This reduces the water content, which guarantees a generative crop response. Especially strongly vegetative varieties or varieties that are weaker on the roots benefit from this.
