Pentagrow lets your agri- and horticultural business flourish

Nice to meet you. Pentagrow is the name. We are a trade organization in fertilizers for agriculture and horticulture. Together with you, we work to achieve maximum quality of your crops with a minimal use of chemicals. With our team of product specialists, we help you to make your agricultural or horticultural business flourish. We advise and guide you, free of charge, on the right product choice for each growth stage of your crop. We do this with the unique products Pentakeep, Nutri-Phite Magnum-S and Wound Paste, of which we are the exclusive worldwide dealer.

Pentakeep not only makes your crop grow faster, but also your yield. On average by 7%.

So what makes Pentakeep so unique? It is the only product in the world that contains 5-Amino Levulinic Acid. This liquid nutritional element supports your crop and activates its metabolism. This will keep your crop stronger and more vital during the cultivation.

”Pentakeep creates a stronger plant, a faster metabolism and a better root system. The hair roots in particular are important for better absorption of all elements. The result is more, nicer and heavier fruit and therefore a better harvest.

Cor den Hertog, general manager

Technically, Pentakeep promotes photosynthesis. As a result, the plant makes more dry matter and absorbs more CO2. As a result, the plants, fruits and flowers grow extra fast. The increased uptake of CO2 improves the balance, making your crop more energetic and less susceptible to disease. Your investment in Pentakeep always pays off. Because adding it to the plant will only cost you 1 eurocent per square meter per week and will give you an additional return of 7% on average. So count the benefits of Pentakeep.

Pentakeep does well on potting soil, rockwool, glasswool, peat, peat moss and coir, so I’m sure it will also fit well into your substrate

Pentakeep does well on regular soil, but also on all artificial soils for plant growth, or substrates. Examples include custom premixed potting soil, rock wool, glass wool, coir, polyurethane foam, peat fiber, peat moss and coir. In short, Pentakeep is sure to fit into your substrate.
