Things You Must Know Before Buying an HID Grow Light

It goes without saying that you must consider something before purchasing anything crucial. HID grow light is considered a crucial element of every indoor grow room. To help growers determine exactly what they need, we’ll ask a series of questions and cast light on the essential considerations in this guide.

What Type Of HID Light Do You Need? MH or HPS?

When talking about high-intensity discharge (HID) light, we think of a large bulb that generates light by igniting the gas inside it. Actually, the flow of electricity gets such a bulb to ignite the gas. That creates a bright light while putting out lots of heat at the same time. These lights are known for being energy efficient and effective.

The HID lights can be classified into:

  • Metal Halide (MH) light – Emitting blue light, this type of light is particularly useful for vegging cannabis. This is because MH bulbs maximize growth during the vegging stage. To provide the desired intensity, MH involves a high light output.
  • High-Pressure Sodium (HPS) light – It emits red-orange-yellow light, which is more favorable during the flowering stage. HPS light is proven to maximize production of flowers and buds during the flowering stage.

Some people prefer using either of these HID bulbs through all stages of the plant growth cycle. However, your best bet is to get both bulbs. Here are a few different options to check out:

Using only MH throughout the grow

This would be the worst option for you, as it wouldn’t result in the great yields during flowering. Obviously, it isn’t a good option because fruiting mostly relies on the blooming process.

Using only HPS throughout the grow

If there’s no other choice and you cannot buy the MH bulbs, this would still be fine. Although HPS bulbs aren’t excellent during veg, you’d still get decent results.

Using HPS during flowering and MH during vegging

That’s what we recommend. This approach is very popular since it lets you utilize the same ballast and reflector while running the bulbs. By switching out the bulb as needed, you will be able to maintain the growth of your plants. Happily, many grow light kits come with both MH and HPS bulbs these days.

Using HPS and MH at the same time

It has emerged that marijuana plants thrive best when getting both blue and red spectrum simultaneously throughout the entire growth cycle. In this case, you should use HPS bulbs as the chief light source — simply put them overhead — and add MH bulbs between the plants. That way, MH and HPS bulbs will complement each other.

Yet, we don’t recommend this option because it significantly increases the cost while giving slightly better yields. Small marijuana growers on a budget should keep away from this option. But if you’re a large-scale commercial grower and expense is no object, then this could be for you.

Do You Need to Go With Single-Ended or Double-Ended HID Bulbs?

Double-ended HID bulbs are nearly 30 percent more efficient than single ended models. So, for the same wattage, they have higher PAR ratings. Moreover, double-ended bulbs last longer than their single-ended counterparts. On the top of that, after around 10,000 hours of use, they can retain 90 percent of their output.

This raises the question: Why don’t all growers go with double-ended lights? What’s the catch? The answer is very simple. They’re very expensive. This is especially true for reflectors that cost up to 100% more. Aside from that, double-ended bulbs generate a lot of heat so that you must have high-end fans installed. Another drawback is that the reflector options for double-ended lights are pretty limited; there are just a couple of styles on the market.

Those on a tight budget who have a smaller grow area and can’t deal with the heat should opt for single-ended bulbs. Double-ended bulbs, on the other hand, are more suitable for commercial growers with the ability to get rid of the excess heat. After a few grows, the longer life and greater efficiency will compensate for the increased cost.

What Reflector Style Is Right For You?

Well, this will depend on your needs. There is a wide range of reflector styles, so it can be a daunting challenge to choose one. Luckily, most reflectors can do a good job, so it’s really hard to go wrong. The differences in light intensity and coverage aren’t that large.

Here are the most popular styles of reflectors:

  • Wing Reflectors
  • Umbrella Reflectors
  • Air Cooled Tube Reflectors (Cool Tube Reflectors)
  • Air Cooled Hood Reflectors (Cool Hood Reflectors)
  • Air Cooled Tube Hood Reflectors (Cool Tube Hood Reflectors)

Each of these reflectors come with its own list of pros and cons. Likewise, each reflector style specializes in a specified situation. The goal is to find one that best suits your growing area and your needs as well.

What Wattage Do You Need?

As far as wattage is concerned, you should focus on bulbs ranging from 250W and 1000W. The HID lights outside of this range are not efficient for indoor growing. For the majority of growers, we recommend 400- or 600-watt bulbs. Avoid 1000-watt bulbs because they run very hot. We also recommend using a few weaker bulbs rather than one stronger bulb. It turns out that this is a more efficient solution.

The size of your grow area is directly proportional to the light power. Those having a large grow room should choose more powerful lights. However, if you use bulbs with extremely high wattage in a small grow room, you’ll likely end up burning your plants.

Wattage (Watts)
Number of Plants
Size of Grow Area
250
3-6
Up to 4 square feet
400
6-9
Up to 9 square feet
600
9-12
Up to 16 square feet
1000
12-16+
Up to 25 square feet

Coverage Area

Make sure to select a size that best suits your grow space. That will not only help you save on energy consumption but also save plants from getting burned. Aside from that, you also need to pay careful attention to the distance between the light and the plant. The light you’re using is likely to be useless if it’s too far. If it’s too close, your plants will be suffering from stress. Remember that the wattage and type of light play a vital role in determining the right position.

Here’s a breakdown of the coverage, the sizes, and distances from plants we recommend.

  • Wattage 250W: Coverage 2″×2″ – 2.5″×2.5″; Distance from plants 12″
  • Wattage 400W: Coverage 3″×3″ – 3.5″×3.5″; Distance from plants 12″
  • Wattage 600W: Coverage 3.5″×3.5″ – 4″×4″; Distance from plants 16″
  • Wattage 1000W: Coverage 4″×4″ – 5″×5″; Distance from plants 21″

Note: Keep in mind that these are just general recommendations since different plant types have the different endurance and tolerance on light intensity.

Light Ballast

The HID grow lights won’t work if they are not properly powered by a ballast. A good light ballast is the one that ensures flexibility, bulb protection, RF shielding, and great dimming ability. Most grow lights involve digital ballast. Such bulbs run cool, produce a high light intensity, and use less electricity.

HID Grow Lights: Our Final Review

If you intend to cultivate marijuana in an enclosed environment, using the best grow lights is of utmost importance. Not all grow lights are favorable or promising though.

For example, you should pick one according to the growth stage of your plants. Also, you need to consider the size of your grow area, the number of plants, reflector style, and wattage when choosing the grow lights.

We have reviewed the best high-intensity discharge (HID) grow lights. That will help you limit your choices and avoid having regrets. Each of these products offers an excellent combination of quality components and good price.

If you have any doubts, compare them and conclude which one would be the right choice for you. Good luck!
