Note: When shopping for LEDs, make sure they contain some amount of green or white (full spectrum) light. Plants grown without at least a tiny amount of green or white light are very prone to nutrient deficiencies and simply don’t grow as well. Learn more about how light spectrums affect cannabis growth!
More Light = Bigger Yields!
(up to a point, it is possible to give your plant too much light!)
There is a larger size MH/HPS grow light available (1000W), but at that size it starts going outside the scope of a “hobbyist” grower as far as ease and yields. In addition to needing a lot of extra cooling which costs electricity, a 1000W HPS grow light is less efficient compared to a 600W grow light (as far as how much light is put out for electricity used). I think most hobbyist growers would be happier with a 600W, or even two 600W lights, over a 1000W
Pros of Fluorescents
Ceramic Metal Halide (CMH) & Light Emitting Ceramic (LEC) Grow Lights
The light from an HPS appears yellow, and is great for flowering plants because the light spectrum stimulates bud production
Some types of induction lights are well suited to stadium lighting but honestly they just aren’t that great for growing cannabis and they come with huge price tags. Even a lot of LEDs are cheaper and you’ll get better results with them. You can learn more about induction grow lights here.
Pros and Cons of HID Grow Lights
Cannabis plants under a T5 grow light – when plants are trained (like these ones in a Scrog setup) you can get pretty decent yields from fluorescents.
Check your breaker board to ensure there are plenty of outlets and enough power to handle your lighting easily. Next, go through your full list of equipment to determine its power usage. If you don’t have enough power capacity, the risk of electrical fires increases markedly.
Certain lights run significantly hotter than others. HIDs, for instance, run extremely hot and need an air conditioning unit. Otherwise, the temperature of your grow room could become excessive and harm your plant’s growth. Please note this is an extra expense to add to the ‘cheaper’ HID setup.
● Reduced efficiency and low yields.
