Hid vs led for growing weed

Solution: When I first wrote this article in 2015, there were far fewer LED options than today. The prices have actually come down quite a bit over the last few years, and there are now some very reasonably priced LED grow lights. For example, ViparSpectra offers many models of LED grow light that cost around the same as an equivalent HPS grow light, and their lights have proven to work great for growing cannabis.

The very first LED panel ever I got was in 2010. It drew 45W out of the wall and cost $130. I remember how excited I was to start using it. Unfortunately, halfway through one of my grows, one side of the panel went dark – the LEDs only lit up on one side after that.

Despite all the pros, I believe that LED grow lights still have 5 major problems that need to be addressed before I’m ready to switch over. If these 5 things were fixed, I believe we’d start seeing more growers everywhere using LED grow lights!

This is actually my biggest beef with the LED grow light industry (I guess not so much the lights themselves). LED grow light companies will usually give you information about bulbs and color spectrum, but there are many that will never actually explain how much electricity the lamp pulls from the wall, and more still don’t provide any information about how the LED is going to perform for your plants.

Solution: Explain how much electricity each LED panel actually draws from the wall, and stop using claims about “equivalency.” But more importantly give us evidence about how your lights work on real cannabis plants. We need more LED grow light companies working with actual cannabis growers!

I really want the benefits of LEDs, but for for me personally, it’s point #1 and #5 that prevent me from switching over from HPS. If LED grow lights needed the same distance from the plants as HPS grow lights, and performed just as well with less electricity I would get one immediately!

2.) High Cost of Premium Models




Traditional forms of lighting that were used in the past and are still used by many growers today include metal halide and high pressure sodium (often abbreviated to HPS). Both of these forms of lighting are considered induction lighting, meaning there are flammable gases and combustion that happen, causing visible light to be emitted. Metal halide lamps often emits a cooler light spectrum, which tends to benefit the vegetation stage of growing. High pressure sodium emits light at a warm 2200K, which is great for the flowering stage of the cannabis plant. Some growers choose to use one style of HID lighting or both during different cycles of the plant’s growing life.

Pros and Cons of LED Grow Lights

When choosing indoor grow lights for cannabis, vegetables, or any other kind of plant, the type of light fixture used can matter. For years, experienced and novice growers alike were reliant on HID light sources to grow their green. Within the past few years, LED grow lights have taken a hold of the market in a huge way and are beginning to eclipse HID grow lights as the best choice for growing plants indoors.


LED grow lights, such as the 400w TOAK from Access Fixtures, have been sweeping the marijuana grow scene for years and the momentum just keeps increasing. This is all for good reason, of course — LED grow lights rely on digital drivers and diodes to emit light instead of traditional combustion methods, and thus are far more efficient. LED grow lights come in many different form factors and styles.

Pros and Cons of HID Grow Lights

There are many short term and long term advantages of using LED fixtures to grow cannabis. While HID fixtures like HPS and metal halide have their place in the growing world, newer LED technology is superior in just about every way.
