HID grow lights are quite affordable. You can find full kits including ballast, bulbs and a reflective hood for just under $200. Even though you can find LED grow lights for half that price, they are perfect for large scale growing.
It’s All In The Spectrum

I also love the design – it features a unique metal body that also acts as a cooling block. The cooling is made even more efficient with the addition of not one, but three cooling fans. These fans run completely silent, which is a huge plus because I can’t stand constant buzzing (and I’m sure you feel the same way).
Grow Space: 2.5×2.5’ coverage at 36” (suitable for vegetative stage) and 2×2’ coverage at 28” (suitable for flowering stage)
October 31, 2020 – LED grow light technology has been improving rapidly especially in the last 1-2 years. Although just about any LED grow light (even the worst ones) can grow good weed, some newer models developed specifically for cannabis are getting better yields, density, and plant growth rates than older and generic models. We are currently doing extensive testing between different LED grow lights to determine which are the “best”. Every grow light on this page gets great results (just look at the pictures to see what to expect) but I’d like to specifically point out certain LEDs where the newest models are beating expectations.
Actual Power Consumption: 520W
Instead of having dozens of small diodes, COB style LED grow lights typically only have a handful of huge COBs, each with strong lenses to direct the light down into the plant. These are rapidly gaining in popularity and are known for having deep penetration into the plant canopy.
