- Products for Vegetable Growers



Grotop Master Dry is based on the unique, dual-density principle. The open fibre structure promotes excellent root distribution within the slab to secure an optimal uptake of water and nutrients throughout the cultivation cycle. Grotop Master Dry is the ideal slab for growers who want to use good water management to steer their plants towards generative growth and produce top-quality crops.

Product Specification

Grotop Master Dry Application

Grotop Master Dry has been especially developed for use with tomatoes and eggplants. In combination with a Plantop Delta or a GRODAN Pro block, it offers growers a generative crop response, right from the start of cultivation.

1. Generative crop response

The combination of the coarse, fibrous structure with the dual density layer enables the slab to be refreshed more easily. Any excess water is drained away more easily so that a lower water content in the slab is achieved and maintained effortlessly, resulting in an enhanced generative crop response. This is particularly advantageous for strongly vegetative varieties or varieties with weaker roots.

2. Superior rooting and plant development

Grotop Master Dry offers a broad control range, making it simple to vary the water content between 50% and 80% (water content day level). The improved controllability of the water and EC levels, together with the dry character of the slab, makes it easier to steer crops towards generative growth during rooting and plant development. The water content can also be easily adapted to suit the specific demands of the season.

3. Perfect control of water and EC

Grotop Master Dry is characterised by its high irrigation efficiency. Resaturating the slab and refreshing the slab solution is easy, which results in a stable EC and WC in the slab. This is achieved using a minimum drain percentage. Even during periods of limited light, the EC remains perfectly controllable without the water content reaching undesirably high levels.

4. Exceptional vigour even with high radiation

The dual density, open structure encourages roots to distribute quickly and more homogenously throughout the slab; new and healthy roots easily develop during the entire cultivation cycle. The uniform, well developed root system secures a maximum uptake of water and nutrients so the crop shows exceptional vigour, even during periods of high radiation. This leads to higher production and better fruit quality.

5. Sustainable water and nutrient use

GRODAN Next Generation fibres do not bind water or nutrients and do not require flushing at the start of the cultivation cycle. A targeted application of water and nutrients from the start of the cultivation cycle enables sustainable water and fertilizer use. In combination with other management strategies this also facilitates improved crop steering and better initial setting and fruit development – resulting in resilient plants that give high production.
