VPD & Root-Zone Balance – Why Climate Control Matters in Stone Wool Cultivation

Vapor Pressure Deficit (VPD) has become one of the most discussed parameters in modern greenhouse and indoor cultivation. It provides growers with a more precise way to understand how plants interact with their environment. Specifically, how temperature and humidity, along with leaf temperature, drive transpiration. While often discussed in the context of climate control, VPD also has a direct impact on root-zone management, especially when using high-precision substrates like stone wool. In this article, we will explore the technical fundamentals of VPD, how it influences plant physiology, and most importantly, how growers can align VPD management with irrigation strategies in stone wool to achieve optimal growth and consistency.

Advanced Nutrient & Crop Steering Techniques in Stone Wool Cultivation

Stone wool has become the preferred substrate for precision cultivation, offering growers unparalleled control over water, nutrients, and oxygen availability at the root zone. As controlled environment agriculture (CEA) advances, one of the most impactful strategies growers can adopt is crop steering. That is a data-driven approach to adjusting environmental and nutritional inputs to guide plant development toward desired outcomes. Whether targeting higher biomass, increased yield, or enhanced quality (such as flavor or cannabinoid concentration), crop steering techniques can transform results in both medicinal and food crop production.

Vegetative and Flowering Stages of Cannabis on Stone Wool

Do you know what has to be taken in account for succesful cultivation? In this knowledge article we will tell you everything you need to know from the end of the propagation stage to the vegetative and flowering stages in cannabis cultivation.

Stone Wool for Cannabis Propagation from Seed and Vegetative Cuttings

Successful cannabis propagation starts with high-quality plugs for cloning or sowing. Whether starting from seed or vegetative propagation in the form of cuttings, there is high importance to use the right and most suitable growing medium.

Stone Wool Saturation: Why it is Important and How to do it Right

Similarly to other growing media, when stone wool is delivered it is dry, meaning, it contains 0% water. In comparison to other substrates, stone wool has many advantages, such as lighter weight, a great moisture holding capacity, more convenient transportation, and longer shelf-life for unused products. Therefore, when a grower plans to start the cultivation of cannabis, the first step (and a very critical one) is to initially saturate the stone wool.
