Hesi Feeding Schedule for Professional Results

If you want to give your plants a professional feeding schedule that’s simple and easy to understand, search no more. The Hesi feeding schedule contains the perfect mineral products that can help you increase yield when growing cannabis in soil, coco coir and even hydroponically.

Hesi Plantenvoeding was founded by Henk Ijpelaar and Sigline Winkler, creating their official name by combining their two names (He-Si) with a Dutch word that means plant nutrition. Hesi has quite a gratifying work ethic; if their clients aren’t satisfied, neither or they, which is why they work as hard as possible to produce quality products.

The Hesi Feeding Schedule | Fertilizers & Boosters

As per usual with many of these feeding schedules, the original chart allows for two growth weeks and just 7 flowering weeks. Keep in mind that these charts are 100% guides; if you’re growing outdoors you’ll need more growing weeks and if you’re growing a sativa plant, you may need to account for more than 7 weeks.

Below, you can find the Hesi feeding Chart that we have made. They are exactly the same as those given out by the manufacturer, although we have accounted for more growth time and slightly adjusted to doses in order to start low and gradually increase. Hesi also has various different product ranges that can be used in soil, coco coir and hydroponically, fitting the needs of all kinds of growers. They also distinguish between fertilizers and boosters, having specific fertilizers for each medium and boosters that are used in all substrates.

Hesi Feeding Schedule Fertilizers

Thanks to the fact that they have three different product ranges for soil. Coco and hydroponics, Hesi has designed three different packs so that growers can get everything they need in one pack; Starter Box Soil, Coco Coir and Hydro.

As well as their base fertilizers and additives, they also have specific products that allow you to adjust the pH in your nutrient solution. They’ve come up with a specific product used to increase pH during both the growth and flowering period. They also stock a product used to decrease pH during the flowering period, which is smoother and more delicate for flowering plants. Also, if you’re looking to make your own clones, you can use Hesi’s ClonFix, a rooting gel that allows your clones to begin rooting much earlier than usual. Hesi has a product for everyone!

Soil

TNT Complex is a growth fertilizer for soil substrates that allows you to give your plants an intense, strong growth period right from the start. This product is great for preparing your plants for an intense flowering period, increasing the size of branches and trunks.

Flowering Complex is the flowering equivalent of the previous product, suitable for soil use. This nutrient combination is perfect for flowering plants. When combined with the right additive, you can accelerate this process even more. Keep in mind that these products are minerals and your plants will need a full root flush before you harvest in order to remove any residues from the roots or buds.

Phosphorus Plus is a soil-exclusive additive that you’ll need to combine with a flowering fertilizer. It’s used when your plants have started to produce young flowers in order to fill them out and fatten them up. It has a little extra phosphorus and potassium, the two most-needed nutrients during the flowering period. In order to increase yield even more, we recommend combining these base products with Hesi’s boosters, too.

Hydroponics

Hydro Growth is a base fertilizer that has been specifically developed for the growth period when growing cannabis hydroponically and aeroponically. This product is absolutely necessary if you’re growing in hydroponics; your plants have no access to nutrients at all in this medium, which is why they need to get all of their nutrients from products used in the water. Their only nutrient source is literally only whatever you feed them in their water.

Hydro Flowering is another base for the flowering period that contains all of the necessary nutrients to get your plants to flower successfully when grown in hydroponics. It contains various elements such as enzymes, important oligo-elements, vitamins and sugars which all guarantee quality flowers. Once your plants begin to fatten their buds up, you’ll need to use this product alongside PK 13/14.

PK 13/14 is the perfect bud fattener for substrates that aren’t soil – it’s ideal for coco coir and hydroponic substrates. When combined with the right flowering base, this product is capable of fattening your buds and increasing their size quite a lot. It gives your plants a little extra phosphorus and potassium, which is quite necessary in hydroponic and coco coir substrates as they lack these nutrients quite a lot.

Coco

Coco Hesi is a product that’s designed specifically for plants grown in coco coir. It contains all of the necessary nutrients that coco coir doesn’t usually have. It can be used during the growth and flowering periods, covering all of the nutritional needs that your plants may have, although manufacturers recommend using it during the flowering period – they prefer to use TNT Complex during the growth period when growing in coco coir.

Hesi Feeding Schedule Boosters

Root Complex by Hesi is capable of stimulating your plants’ roots, allowing them to absorb many more nutrients. After just a few uses you’ll begin to see the results. Your plants will grow incredibly large and healthy. This vitamin-rich product accelerates your plants’ internal processes, making them grow much faster.

SuperVit is a product that can be used during the growth and flowering periods. It can be used after just 10-15 growth days. It contains large amounts of vitamins and amino-acids, up to 25 different ingredients, each of which has its own way to help your plants to grow and prosper. As well as stimulating general growth, it also stimulates your plants’ metabolism which allows them to absorb any nutrients given to them much faster.

Powerzyme is an organic product that you absolutely need to use when growing using minerals; it gets rid of any residues that end up stuck in your plants’ substrate. It contains an enzyme complex that can remove any chemical, mineral and organic residues. It also activates beneficial microbial life in substrates, which protects your plants from insect and fungi attacks or infestations.

How to use the Hesi Feeding Schedule

Remember to always keep an eye on your pH and EC levels, making sure that they’re adequate for cannabis plants, as mineral nutrients can modify these parameters quite a lot. These charts are simple guides, which means that you should always follow the signs your plants’ are giving you rather than following the feeding schedule blindly. If your plants have a longer growth or flowering period, simply follow the last week’s dose until it’s time to flip them to flower or to wash the roots.
