Fixtures come in all shapes and sizes and can usually accommodate 4-12 long fluorescent bulbs; a standard size is 8 bulbs. Fixtures usually have a reflective material to bounce light in one direction, down on your plants.
HIDs have been the standard in indoor weed growing for decades, but LEDs are quickly catching up to them.
When growing outdoors you can harness the power of the sun, but in an indoor environment, sunlight is mimicked through the use of grow light bulbs, which aim to display the same spectrum of light as the sun.
LEDs (light emitting diodes) are relatively new to the cannabis growing world, compared to HPSs, MHs, and CFLs, but they are quickly proving to be the way of the future. LEDs may be more expensive to buy initially, but they are far more efficient and kinder to the environment and your electricity bill. Some cities even give tax breaks to commercial growers who install or switch to LEDs because they’re better for the environment.
Best HID grow light brands
New LED grow lights come out all the time, but knockoffs abound. There are a lot of cheap LEDs that don’t produce the right spectrum of light for plants.
There are daylight bulbs and warm white bulbs; the former better for vegetative growth, and the latter for flowering.
These HID bulbs usually contain sodium, mercury, and xenon, and produce a yellow/orange light, and are commonly used for flowering plants. Some growers will start plants under MH bulbs and switch them to HPSs when plants go into the flowering stage, using the same hood. These lights also require a ballast.
Types of marijuana grow lights
One of the crucial elements a cannabis plant needs is light. During photosynthesis, a plant converts light energy into chemical energy, allowing it to grow strong and healthy, and with cannabis in particular, light also fuels bud production.
For HIDs, light occurs as an arc between two nodes inside the bulb. The gas contained in these bulbs is what makes MHs and HPSs different. HID bulbs are usually more expensive than the reflective hoods that hold them.
The uninitiated may believe that house lights are sufficient for cannabis plants. However, even if you use LED lighting, it is almost certainly too weak to help a marijuana crop in a grow room. Remember, your home’s lights are designed for your eyes rather than plants. The light spectrum required to help us see is very different from what plants require for photosynthesis.
Why Should I Use Indoor Marijuana Grow Lights?
It might sound strange that a plant prefers a type of light. However, different colored lights are mostly just different wavelengths and intensities. Due to this difference in wavelength, the plant prefers stronger or weaker lights at various stages of its development.
Fluorescent Grow Lights – Best Used for Small Grows
High-Pressure Sodium, or HPS, grow lights are far more efficient than other forms of HID. They emit a gentler, yellow light that cannabis prefers when it is in the flowering stage. This yellow light helps encourage intense bud production. In addition, it allows you to configure the eventual size of your harvest more precisely.
The traditional panel-style of LED grow lights are also efficient for growing cannabis. They are specifically designed with small and medium wattage to provide appropriate lighting. They are compact, and nowadays, manufacturers are now focusing on this style of lights. They resemble similar features of both COB-style light and quantum board.
Maintain Moisture and Save Water: Other grow lights emit heat that soaks the water in the plants. Thus, you will save a significant amount of water if you use LED lights. Because LED grow lights can also preserve the moisture of cannabis and produce a higher yield.
Use LED Grow Lights for Growing Indoors
They have strong lenses and throw light straight to the cannabis plants. It means the plants will receive efficient light up to their roots. You will also find auto COBs and single COB lights that you can choose as per your need.
