Nutrient and Fertilizer Interactions
Plant fertilization is a sophisticated science that requires understanding both plant needs and the interactions between nutrients and the fertilizer salts used to supply them. Certain nutrient combinations can interfere with uptake, while improper fertilizer combinations may lead to precipitation or other reactions that make nutrients unavailable for absorption.If you’re using pre-mixed fertilizers from a reputable brand, these incompatibilities aren’t a concern, as such products are formulated in a balanced way to ensure chemical compatibility. However, if you prefer to …

Chelation and Chelates
Plants need secondary macronutrients and micronutrients in smaller quantities than primary macronutrients, and yet deficiencies in the former can be just as harmful to growth and yield as deficiencies in the latter. Micronutrients are particularly prone to becoming unavailable due to nutrient lockout or precipitation from the nutrient solution. Chelation helps to prevent this.In this blog post, we explain what chelation and chelates are, how they work and why they’re essential for nutrient uptake and utilization.Science of chelates A chelate is …

Understanding NPK Sources and Ratios
Nitrogen, phosphorus and potassium—commonly referred to as NPK—are the three essential macronutrients. They’re called macronutrients because plants require them in large quantities, which is why they’re often regarded as the most important for plants.Each plays vital roles in plant development. Nitrogen is a fundamental part of both amino acids, the building blocks of protein, and nucleic acids (DNA and RNA), while phosphorus is essential for photosynthesis, and potassium regulates water use.Because growers must supply these nutrients in hydroponics, it’s important …

Cannabis Plant Morphology
Plant morphology refers both to the scientific study of the external physical structure and appearance of plants and to the descriptive terminology used to characterize these traits.[1] In this blog post, we’ll provide an overview of the descriptive morphology of Cannabis sativa. Morphology matters The morphology of cannabis varies throughout its life cycle in relation to such factors as genetics or strain, environmental conditions and growing techniques. Its height impacts how much light it can receive, as well as its biomass and …

Understanding EC in Hydroponic Systems
Electrical conductivity (EC) measures a solution’s ability to carry an electrical charge. In hydroponics, EC is an important indicator of nutrient concentration, as it reflects the amount of dissolved fertilizer salts in the nutrient solution. By monitoring EC at different points in the system, growers can ensure plants receive adequate nutrients and track nutrient uptake.In this blog post, we’ll break down how EC works, its impact on plant development, how to measure it and what to do if adjustments are …
