HID Lights are typically divided into a few different varieties or sub-categories:
The lighting required by cannabis plants varies according to their stage in the growth cycle. Young plants require a different light spectrum from their mature counterparts. For example, Metal Halide lights are associated with plants in the vegetative stage. In contrast, HPS lighting is frequently used in the blooming phase.
There are plants like microgreens that can flourish with a basic lamp. However, marijuana plants require fairly strong and consistent light to help them into the blooming phase. Remember, when you grow cannabis indoors, you’re competing with the sun in terms of light! This means you need high-power lights in your plants’ grow space.
Fluorescent Grow Lights – Best Used for Small Grows
The two types of fluorescent lights are T5 and CFLs. The former is long and narrow, while the latter are twisted into the shape. They have cool, warm, or full-spectrum colors. Growers sometimes use them because they are cheap to buy and have a low energy consumption, saving money on energy bills. They also provide a pleasant color for an indoor growing site.
● They can require large boards of LEDs due to their relatively low power.
One great benefit of LED grow lights is that they create comparatively little heat compared to other types of light.
Yes. However, a plant’s LED light power requirements change during the growth cycle. As your plants get larger, they’ll need a high-powered LED to thrive. The standard LED bulb that works during the first few weeks of growth is insufficient in the flowering stage.
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! However, they do require extra setup compared to the other grow lights because chances are you will need a fan to vent out heat from your grow space.
Keeping CFLs close results in the best yields and growth
These are actually just two names for the same thing. This type of metal halide bulb uses ceramic as part of the lamp just like an HPS. As a result, CMH bulbs are more efficient than regular MH lights (though still not as efficient as HPS bulbs).
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.
CFL grow lights are the twisty-looking bulbs you can find anywhere you normally buy light bulbs. They produce a great spectrum for growing cannabis and can be used in tiny spaces where no other grow light would fit such as the inside of a cabinet.
High Pressure Sodium grow lights are often used during the flowering stage because they are very efficient and their yellow light stimulates bud production. HPS grow lights in the flowering stage get better yields per watt of electricity than any other type of grow light available today, which is a big part of why they are so popular.
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
T5 grow lights are one of the most easily available types of grow lights and are used to grow many different types of plants. As a result, they’re available in many garden and home improvement stores.
