Photon penetration refers to the depth or distance that photons of light can effectively penetrate into the canopy of plants within a growing area. Factors such as light intensity, spectrum, and canopy density influence photon penetration, with deeper penetration facilitating better light distribution and access to lower canopy layers, promoting uniform plant growth and development. Some photon can not penetrate to the root, so growers may use under canopy grow light to supplement it.
Environmental Parameters:
VPD (Vapor Pressure Deficit):
Vapor Pressure Deficit (VPD) is a measure of the difference between the amount of moisture in the air (absolute humidity) and the maximum amount of moisture that the air can hold at a given temperature (saturation vapor pressure). VPD indicates the relative dryness of the air and influences transpiration rates and plant water uptake. Maintaining optimal VPD levels is crucial for regulating plant growth, nutrient uptake, and overall plant health. In greenhouse growing, growers usually apply controller and dehumidifier to their growing. We have an article of detailed information about it., Click to see>> VPD
RH (Relative Humidity):
Relative Humidity (RH) is a measure of the amount of water vapor present in the air relative to the maximum amount of water vapor the air can hold at a specific temperature, expressed as a percentage. RH plays a significant role in indoor growing environments, affecting plant transpiration, water loss, and susceptibility to diseases such as powdery mildew. Proper RH management is essential for maintaining optimal plant health and minimizing environmental stress.
EC (Electrical Conductivity):
Electrical Conductivity (EC) measures the ability of a solution to conduct electricity, indicating the concentration of dissolved salts or ions, such as nutrients, in a nutrient solution or growing medium. EC is used to assess nutrient levels, monitor nutrient uptake by plants, and adjust nutrient solutions to maintain optimal nutrient concentrations for plant growth and development.

pH is a measure of the acidity or alkalinity of a solution, determined by the concentration of hydrogen ions present. In indoor growing, pH levels in nutrient solutions and growing mediums significantly influence nutrient availability, uptake, and plant growth. Maintaining proper pH levels is critical for ensuring optimal nutrient absorption, preventing nutrient deficiencies or toxicities, and promoting healthy plant development.

Carbon Dioxide (CO2) is a crucial component of photosynthesis, serving as a substrate for carbohydrate synthesis in plants. In indoor growing environments, CO2 levels directly influence photosynthetic rates, plant growth rates, and overall productivity. Supplemental CO2 enrichment is often used to increase CO2 concentrations in enclosed growing spaces, optimizing photosynthetic efficiency and boosting plant growth and yield. If you need, we can recommend CO2 burner, CO2 regulator and detector suppliers to you.
Aeration:
Aeration refers to the process of providing oxygen to the root zone of plants through the circulation of air or oxygenated water in the growing medium. Adequate aeration is essential for promoting root health, nutrient uptake, and microbial activity, as well as preventing root suffocation, anaerobic conditions, and root diseases.

Root Zone Temperature refers to the temperature of the growing medium surrounding the roots of plants. Root zone temperature influences nutrient uptake, root growth, and overall plant metabolism, with optimal temperatures varying depending on the plant species and growth stage. Maintaining appropriate root zone temperatures is critical for maximizing nutrient absorption, root development, and plant health.
