The most common types of modern GROW LIGHTS

Excess light can damage your cannabis plants as much as too little light. Learn all you need to know about light as it relates to cannabis, and how to properly set up your grow lights for massive indoor harvests.

Cannabis Cultivation Tips: How To Set Up Indoor Grow Lights


THE  MOST COMMON TYPES OF MODERN GROW LIGHTS


Contemporary indoor cannabis cultivation usually involves at least one of three artificial light sources:  LED. Frequently, growers use a combination of grow lamps. Of course, there are other, more antiquated lighting technologies, but they are all pretty much “Betamax” lamps. This blog will focus on the most common lighting used by the 21st-century cannabis cultivator. We are going heavy on the practical grow room advice without relying on the pseudo-scientific stats.

HID or high-intensity discharge lamps have been the grow lights of choice for every kind of indoor grower from beginners to pro cultivators since the early 1990’s at least. Over the years, lamps have become more efficient, ballasts have gone digital, and reflectors have gotten bigger and better. Growers that favour HID are big believers that lumens are the only output statistic that matters when it comes to lights.




Sure, CMH or ceramic metal-halide has come on the scene and the 315W CMH bulb is impressive, but a rather expensive upgrade for a standard MH or metal-halide lamp. Moreover, 315W CMH is not quite as high performance as a high-end dual spectrum/agro 600W HPS or high pressure sodium lamp. Similarly, CFL shows some promise, but always runs a distant second to the tried and trusted HID.




LED or light-emitting diode is the up-and-coming breakaway technology that looks to end the reign of HID for cannabis cultivation. The latest generation of LED systems are now capable of producing comparable, and in some cases, superior quality marijuana than the average HID set-up. PAR or photosynthetically active radiation is the metric that LED zealots consider most important.




It’s best not to get too obsessed about the various new measures of light and modified light spectrums. Keep it simple. Think of light in terms of watts and electricity bills. Next is the question, “How much power consumption?” Followed by, “How much heat will the lamp produce and how much light will it emit?”
