For those seeking a professional and user-friendly nutritional plan for marijuana cultivation, Hesi’s feed charts provide mineral-based products designed to maximize plant yield across soil, coco, or hydroponic mediums. This post, complete with all the details for using the Hesi feeding chart in soil, coco, and hydro setups, ensures correct application.
Origin of the Hesi brand
Hesi Plantenvoeding is a Dutch brand specializing in mineral-based fertilizers and additives for marijuana growing aimed at delivering quality results. Founded by Henk Ijpelaar and Sigline Winkler, the brand’s name combines their names with a Dutch term meaning “plant nutrition.”
Hesi’s work philosophy focuses on satisfying growers through innovation and high-quality products.
Hesi fertilizers and boosters
Typical of manufacturer-provided schedules, Hesi suggests two weeks of growth followed by about seven weeks of flowering. It’s important to note these schedules are advisory; outdoor growers might need more than two weeks of growth, and long-flowering sativas may require additional time.
Hesi offers various product lines for soil, coco, and hydroponic cultivation, making their fertilizers and additives accessible to all growers.
Hesi fertilizer lines
With three distinct product lines for soil, coco, and hydroponic cultivation, Hesi has designed three different starter packs (Starter Box Soil, Coco, and Hydro) to meet all growers’ needs in one place. Besides base fertilizers and additives, Hesi also offers products for pH adjustment during growth and flowering phases, including a gentler pH down product for the flowering period. ClonFix, a rooting gel, helps cuttings root much faster.
Hesi soil
For soil cultivation, Hesi offers products like:
- TNT Complex, a growth base fertilizer for soil that promotes strong and robust plant growth, preparing them for intense flowering by increasing trunk and branch size and strength.
- Bloom Complex, the flowering period equivalent of TNT Complex, offers a nutrient mix perfect for blooming plants and, when combined with the right additive, can speed up the process. These mineral-based products require a thorough root flush towards the end of the cycle to ensure a clean taste in the final product.
- Phosphorus Plus, a soil-specific additive to be combined with the flowering base fertilizer, supports young flowers in filling out and increasing in size by providing extra phosphorus and potassium, crucial nutrients during the flowering period. For enhanced plant yield, combining these bases with Hesi boosters is recommended.

Hesi Hydroponics
In hydroponics, Hesi provides quality products like:
- Hidro Floración: Hydro Growth is a base developed specifically for the growth period in plants cultivated hydroponically and in aquatic mediums. This product is indispensable for those wanting to maintain a hydroponic garden, as in such cultivation methods, your plants lack a traditional substrate. This means the sole source of nutrients is what’s provided in the irrigation water. Therefore, this product contains all the necessary food for the plants.
- Hidro Floración (Bloom) is another base that contains a high number of essential nutrients needed for marijuana plants to bloom successfully. This base fertilizer is enriched with various elements, such as enzymes and important trace elements, in addition to vitamins and sugars to ensure quality buds. When plants begin to bulk up their buds, it’s time to start combining this product with PK 13/14.
- PK 13/14 by Hesi is a bud enhancer designed for aquatic mediums and coco substrates. When combined with the appropriate flowering base, this product can thicken and increase the size of your plant’s already produced buds. It provides an extra boost of phosphorus and potassium to the plants, which is especially necessary in hydroponic or coco cultivation, where far fewer nutrients are available in the substrate.

Hesi Coco
Hesi Coco is specially formulated for coco-cultivated plants, covering all nutritional needs, though it’s recommended to use only during flowering, with TNT Complex preferred during the growth phase.

Hesi Boosters
- Root Complex is designed to stimulate your plants’ roots so they can absorb more nutrients. After just a few applications, you will notice the results; your plants will experience lush vegetative growth. It is a product rich in vitamins that speed up all of your plants’ internal processes, making them grow faster.
- SuperVit is a product that can be used during both the growth and flowering periods. It is typically applied after about 10-15 days of initial growth. It contains an incredible number of vitamins and amino acids, which aid in plant development. In addition to stimulating overall plant growth, it also enhances metabolism, enabling plants to more quickly absorb the nutrients provided to them.
- Power Zyme is an organic product that is essential when cultivating with mineral products, as it helps to eliminate all residues that accumulate in the substrate. It consists of an enzyme complex that cleanses any substrate of chemical or mineral, and even organic residues. It also significantly activates the beneficial macrobiotic life in the substrate, protecting plant roots from attacks and pathogens.

How to use Hesi feeding charts?
It’s crucial to consistently measure and tweak the pH and EC to the required levels when cultivating with mineral products. These schedules serve as a guideline, which means you’ll need to pay attention to signals that your plants are sending you. Consider these schedules a guide; if your plants experience or demand an extended growth or flowering phase, you should simply continue administering the dosage from the final week of that phase, ensuring a thorough root flush a couple of weeks prior to harvest. This approach ensures your plants receive the tailored care they need for optimal growth and blooming.
