HIDs are very well suited to growing cannabis and very easy to use once they’re set up. If your main goal is to get the highest yields possible, then HIDs are the way to go!

HIDs are great at growing cannabis, but they also get very hot and are usually hooked up to an exhaust to help vent out heat.
