What is light

What is light? Light can be described as electromagnetic energy or waves moving from one point to another. Each wave for a certain wavelength looks the same; it has the same beginning and ending, and the same height and width. Some wavelengths are shorter, meaning faster wave formation, while other wavelengths are longer (slower wave […]

Ultraviolet (UV) light

Ultraviolet (UV) light Ultraviolet (UV) light falls outside the visible light range, or PAR, between 100 and 400 nanometers. This type of light can be divided into UV-A, UV-B, and UV-C.  UVA lies between 320 – 400 nm and is also called Near UVUVB lies between 290 – 320 nm and is also called Middle […]

Plant nutrients

Plants absorb nutrients from the soil that are essential for growth, development, and survival. These nutrients can be divided into primary (or macro), secondary, and micronutrients. Plants take in these nutrients through their roots. Some nutrients may move freely throughout the plant, while others cannot. If a nutrient can be moved, the plant will be […]


What is photosynthesis? Photosynthesis is a process where plants transform photon (light) energy into chemical energy needed for growth. In contrast to most other living creatures, plants use carbon oxide (CO2), along with water, light, and minerals to fuel their growth and energy needs. They convert this into oxygen and organic compounds. You could say […]


Photosynthetically Active Radiation PAR stands for Photosynthetically Active Radiation. PAR includes the light ranging from 400 to 700 nanometers that plants use for photosynthesis. The amount of PAR is expressed as the number of micromoles (µmoles) of photons being emitted by the light source. PAR can be used in determining the strength and overall quality […]

Different types of grow light

Different types of grow lights Home and professional growers have used a different variety of light sources that distribute their light differently. And while some are a big fan of HPS lamps, others swear by LEDs. Horticraft Holland thinks LED has many benefits over other types of light sources, which we will discuss in another […]
