HESI Fertilizers and Additives for Cannabis Plants

HESI Plantenvoeding is a company that manufactures and distributes fertilizers and additives for growing cannabis.

Located in Kerkrade, a Dutch city in Limburg, HESI is a combination of their founders’ names, Henk Ipelar and Siglinde Winker. Plantenvoeding means vegetable nutrition in Dutch.

HESI, A Family Company

HESI started off and is still a family company. They started out in 1993; Siglinde Winkler was in charge of a lab that manufactured products for aquariums. The owner of the factory had a plant nursery that was struggling, so he asked Siglinde for help because he knew she was good with plants. After a lab analyses, Siglinde appeared with fertilizer that managed to save his plants.

Henk, around the same time, had just bought the Limbogrow growshop. Surprised by the quality of his own yields, he gave the products to Siglinde to try and her customers were surprised at the successful results.

On April 1st 1996 HESI was founded. They outsourced their products to Germany, where the cannabis market was just starting in comparison to the Dutch market, opening the door to new customers. In no time at all they went from making homemade fertilizers to being in over 35 countries.

Which HESI Base Fertilizer to Choose

HESI fertilizers combine macro and micronutrients with enzymes, vitamins and amino-acids in order to get the best possible results.

Here are your HESI fertilizer options depending on the substrate in which you’re growing:

For Growing Cannabis in Soil

  • TNT Complex: this is a complete fertilizer designed for the growth period in soil. This product contains organically-sourced nitrogen (urea). It’s also enriched with vitamins B1, B2, B3, vegetable sugars and amino acids.
  • HESI Flowering Complex: this is a complete fertilizer designed for the glowering period. It contains all of the macro and micronutrients necessary for this stage, including amino acids and vitamins. From the second half of the flowering period you’ll need to use Phosphorus Plus in order to fatten the buds. HESI’s products for soil are slightly acidic, allowing for correct pH levels in your nutrient solution.
