Why do plants grow better in blue light? Guide for 420 Beginners
Indoor grow lights are special lighting systems that take the place of sunlight when you are cultivating weed and other plants, fruits, herbs, vegetables and flowers indoors. These lights can provide a spectrum of light just like the sun does. Grow lights allow your plants to have a growth quality similar to what the sun can provide.
There are a variety of grow lights for marijuana available. They may differ in operation but they all have the same purpose — to help your marijuana plants flourish.
Blue light is usually referred to as radiation with wavelengths between 400 and 500 nm. This waveband is within the visible spectrum, has relatively high energy, and has pronounced effects on plant growth and flowering. Our perception of blue light, especially at shorter wavelengths (for example, 400 to 425 nm) is low compared to green.
light. In contrast, blue light is considered equally effective as green or red light at driving photosynthesis. Thus, while blue light can appear somewhat dim to us, it has high energy and is useful for plant growth applications.
Effects of Red and Blue Light on Plants
What we perceive as white light from the sun is actually made up of all the colors of the rainbow. The three major colors of light are red, blue, and green.
The effect of blue light on plants is directly related to chlorophyll production. Plants that receive plenty of blue light will have strong, healthy stems and leaves.
Red light is responsible for making plants flower and produce fruit. It’s also essential to a plant’s early life for seed germination, root growth, and bulb development.
Blue light fits with the absorption peak of chlorophylls, which do photosynthesis to produce sugars and carbons1. Sugars and carbons are essential for plant growth, as they are the building blocks for plant cells. However, blue light is less effective than red light for driving photosynthesis. This is because blue light can be absorbed by lower-efficiency pigments like carotenoids and inactive pigments like anthocyanins2. As a result, there is a reduction of blue light energy that makes it to the chlorophyll pigments. Surprisingly, when some species are grown with just blue light, plant biomass (weight) and photosynthesis rate are similar to a plant grown with just red light3. This tells us that the importance of blue light for photosynthesis and growth is species-dependent.
Best LED Grow Lights for Indoor Plants 2020
KropTek iKROP-660W SUNBLAST LED Grow Light
A high-powered LED grow light designed for top lighting or supplementary lighting in indoor grow rooms and glasshouses. Emitting high levels of light, the iKrop-660 can operate as a stand-alone light fitting or can be connected to other iKrop-660s to create a larger luminaire.
In this way, a 660W LED grow light can be created by attaching 2 of the iKrop-330s together and a 1000W LED grow light can be created by attaching 3 units together. The iKrop-330 SUNBLAST is a fully waterproof light fitting and can emit 216 μmol/m²/s at a distance of 1.5m.
Viparspectra released their new quantum style LED grow lights. The VP Series VP1000 and VP2000 models are a nice upgrade from previous Viparspectra grow light models.
The previous Viparspectra grow lights were a bit weak for growing cannabis unless you bought the more expensive models. The Viparspectra Pro Series feature stronger light than the previous models, which makes these a much more attractive option for cannabis growers looking for a familiar brand to grow with.
