Biogreen PK 13/14 is an early flowering additive in high concentration gel format, formulated from years of research and made exclusively with top quality raw materials. Its function is to provide phosphorus and potassium at the critical moment of the beginning of flowering, providing plants with all the minerals necessary for the rapid and explosive development of flowers from the first weeks.
Its highly bioavailable gel formula ensures immediate absorption of nutrients, stimulating energy transfer and flower formation in the vital stage of early flowering.
Composition and analysis
Its richness in phosphorus and potassium, together with the presence of boron, copper and iron, guarantees a flowering start of maximum intensity and quality.

Frequently asked questions
-
Biogreen PK 13/14 is a powerful flowering additive based on phosphorus and potassium in a balanced 13/14 ratio. It is designed for the final stretch of the grow, when the plant needs extra amounts of these minerals to develop and fatten the flowers, giving big, heavy and compact buds.
-
It is a bio-mineral supplement enriched with humic acids, which improve nutrient efficiency and uptake. It also contains magnesium, boron, copper and iron, and is made with top quality raw materials developed over years of research.
-
Add it to the irrigation water from week 5-6 of flowering, dosing it alongside your base fertiliser over several days depending on the size of the plant. Being a liquid, it is very easy to dose when watering.
-
Stop applying it 1-2 weeks before harvest to avoid residues in the plant. The dose is only a guideline, so adjust it to the variety, the stage and the size of your plants.
-
PK 13/14 boosts flower fattening and density by supplying the key minerals at the point of highest demand. The result is bigger, firmer and heavier buds, with better flower development from the moment you start using it.
-
Store the product in a frost free place, between 15 and 40 degrees. Gloves and a mask are recommended when handling it.
