Feeding schedules HESI
Contents
The brand Hesi is recognized for its nutrient, suitable for different indoor growing systems, whether in soil, coco, or hydroponics. Whether you are using a system DWC (Deep Water Culture), NFT, or aeroponic, Hesi offers balanced nutrient solutions for every phase of your plants' development. With specific formulations like TNT Complex, Hydro Bloom, and Hesi Boost, these nutrient ensure optimal growth and abundant flowering, while simplifying nutrient management.
In this guide, you will find the detailed cultivation schedules for Hesi, tailored to different substrates. Following these schedules will allow you to optimize the yield and health of your plants while maintaining a precise control over the EC and pH of your nutrient solution. 🌱
First of all, remember that it is always better to start with half of the recommended dose, as your potting soil often already contains nutrient, which could lead to overloading.
Feeding schedule in Soil with Nutrient Hesi

The Hesi Soil range ensures complete and balanced nutrition, tailored to the needs of plants at every stage of their development. This program is based on TNT Complex during growth and Hesi Bloom during flowering, accompanied by essential additives such as Root Complex, SuperVit, Hesi Boost, Phosphor Plus and PowerZym. Start with progressive doses and adjust according to the plants' development.
Growth phase (weeks 1 to 4)
-
Weeks 1 and 2:
Apply Hesi TNT Complex (15 to 25 ml/10 L of water) to promote healthy and rapid growth. Add Hesi Root Complex (20 ml/10 L) to stimulate rooting and strengthen the plant. SuperVit (1 drop/10 L of water, 1 to 2 times a week) boosts vitality and nutrient assimilation. -
Weeks 3 and 4:
Increase Hesi TNT Complex from 25 to 50 ml/10 L for vigorous growth. Maintain Hesi Root Complex (20 ml/10 L) until the end of the 1st week of flowering and continue SuperVit at the same rate.
Flowering phase (weeks 5 to 12)
-
Week 5 (beginning of flowering) :
Replace TNT Complex with Hesi Bloom (50 ml/10 L). Add Hesi Boost (20 ml/10 L only in week 5) to stimulate the transition to flowering. PowerZym is recommended to dissolve plant tissues and improve nutrient absorption. SuperVit continues at a rate of 1 to 2 times per week. -
Weeks 6 and 7:
Maintain Hesi Bloom (50 ml/10 L). Hesi Boost is not applied during these weeks. Continue PowerZym and SuperVit. -
Weeks 8 to 10:
Reintroduce Hesi Boost (20 ml/10 L, once a week starting from the 3rd or 4th week of flowering depending on the plants' development). Start Hesi Phosphor Plus to boost yield and improve flower formation. Hesi Floraison (50 ml/10 L) and PowerZym continue to be used. -
Weeks 11 to 12 (rinsing):
Stop all nutrient and use only pure water to eliminate residues and improve the taste quality of the harvest. SuperVit is also stopped.
Feeding schedule in Coco with Nutrient Hesi

Cultivating in a coco substrate with Hesi follows a similar approach to that in soil, but with the use of Hesi Coco instead of Hesi Bloom during the flowering phase. Since coco is an inert substrate, the nutrient supply must be regular and adjusted to ensure optimal growth and flowering.
Growth phase (weeks 1 to 4)
-
Weeks 1 and 2:
Apply Hesi TNT Complex (25 ml/10 L of water) to stimulate growth. Add Hesi Root Complex (20 ml/10 L) for optimal rooting and SuperVit (1 drop/10 L of water, 1 to 2 times a week) to enhance nutrient absorption. -
Weeks 3 and 4:
Increase Hesi TNT Complex to 50 ml/10 L to support vegetative development. Maintain Hesi Root Complex (20 ml/10 L) until the end of the first week of flowering and continue SuperVit at the same rate.
Flowering phase (weeks 5 to 12)
-
Week 5 (beginning of flowering) :
Replace TNT Complex with Hesi Coco (50 ml/10 L). Apply Hesi Boost (20 ml/10 L only in week 5) to stimulate flowering. PowerZym is recommended to improve nutrient absorption and dissolve organic residues. SuperVit continues at a rate of 1 to 2 times per week. -
Weeks 6 and 7:
Maintain Hesi Coco (50 ml/10 L). Hesi Boost is not applied during these weeks. Continue PowerZym and SuperVit to support flower growth. -
Weeks 8 to 10:
Reintroduce Hesi Boost (20 ml/10 L, once a week starting from the 3rd or 4th week of flowering depending on the plants' progress). Start Hesi Phosphor Plus to improve the structure and density of the flowers. Maintain Hesi Coco (50 ml/10 L) and PowerZym. -
Weeks 11 to 12 (rinsing):
Stop all nutrient and use only pure water to eliminate residues and optimize the taste of the harvest. SuperVit is also stopped.
This program guarantees vigorous growth and abundant flowering in coco substrate, by maximizing nutrient availability for a high-performing crop. 🌱✨
Feeding schedule with Nutrient Hesi Hydro

Hydroponic culture with Hesi allows for rapid absorption and precise control of nutrients. This program is based on Hydro Growth in the vegetative phase and Hydro Bloom in flowering, complemented by essential additives such as Root Complex, SuperVit, Hesi Boost, and Hesi PK to maximize growth and flowering. The EC must be adjusted at each phase for optimal assimilation.
Growth phase (weeks 1 to 2)
-
Week 1:
- Hesi Hydro Growth: 25 ml/10 L
- Hesi Root Complex : 20 ml/10 L
- SuperVit : 1 drop/5 L of water (1 to 2 times/week)
- Recommended EC: 1,4 - 1,6 mS/cm
-
Week 2:
- Hesi Hydro Growth : 50 ml/10 L
- Hesi Root Complex : 20 ml/10 L
- SuperVit : 1 drop/5 L of water
- Recommended EC: 1,6 - 1,8 mS/cm
Blooming phase (weeks 3 to 8)
-
Week 3 (beginning of flowering) :
- Replace Hydro Growth with Hesi Hydro Bloom: 50 ml/10 L
- Hesi Boost : 20 ml/10 L (only in week 3)
- Recommended EC: 1,8 - 2,0 mS/cm
-
Week 4:
- Hesi Hydro Bloom: 50 ml/10 L
- Recommended EC: 2,0 - 2,2 mS/cm
-
Week 5:
- Hesi Hydro Bloom: 50 ml/10 L
- Hesi PK : 2.5 ml/10 L

- Recommended EC: 2,3 - 2,5 mS/cm
-
Weeks 7 and 8:
- Hesi Hydro Bloom: 50 ml/10 L
- Hesi PK : 7.5 - 15 ml/10 L depending on the development of the plants
- Recommended EC: 2,3 - 2,5 mS/cm
