- Increased Yields: Directly contributes to a heavier harvest through improved bud mass.
- Boosted Resin Production: Stimulates the production of essential oils and terpenes, enhancing aroma and potency.
- Optimised Nutrient Uptake: Provides readily available phosphorus and potassium for efficient absorption.
- Suitable for Various Growing Mediums: Effective in hydroponics and coco coir.
- Improved Plant Vigour: supports robust flowering.
How to use Hesi PK 13/14
Dosage of 2.5-15ml per 10 litres of nutrient solution, gradually increase the dosage starting in the second half of the flowering phase. Monitor your plants closely and adjust the dosage as needed. Use in conjunction with your base nutrient solution for optimal results. Flush your growing medium with plain water before harvest.Available in 1 litre and 5 litres.Frequently Asked Questions
Can I use Hesi PK 13/14 with other nutrient brands?
While Hesi PK 13/14 is designed to complement the Hesi nutrient line, it can be used with other high-quality nutrient brands. However, it is essential to monitor the EC (electrical conductivity) of your nutrient solution to avoid overfeeding.When is the best time to start using Hesi PK 13/14?
The optimal time to introduce Hesi PK 13/14 is during the second half of the flowering stage, when the plant's demand for phosphorus and potassium increases significantly.How often should I apply Hesi PK 13/14?
Apply Hesi PK 13/14 with each watering or feeding during the second half of the flowering phase, following the recommended dosage.Is PK 13/14 necessary?
Whether or not PK 13/14 is "necessary" depends on your cultivation goals. It's designed to significantly enhance the flowering stage, leading to larger, denser buds and increased yields. If you're aiming for maximum production, especially in intensive growing setups like hydroponics, a PK booster can be very beneficial. However, healthy plants can still produce a harvest without it. It is an additive that boosts production.What is the difference between PK 13/14 and 9/18?
The numbers refer to the ratio of phosphorus (P) to potassium (K) in the nutrient solution. PK 13/14 contains a ratio of 13 parts phosphorus to 14 parts potassium. PK 9/18 contains a ratio of 9 parts phosphorus to 18 parts potassium.Essentially, the difference lies in the concentration of each element. Some growers believe that the 9/18 ratio provides a more balanced uptake of potassium, while others prefer the 13/14 formulation. Different plant strains, and growing conditions may benefit from one or the other. Many nutrient producers have their own research, and opinions on which ratio is best.
