HPS bulbs are great for flowering stage because of the yellow light spectrum. We’ve got 5 picks of the best 400w HPS bulb brands to support your plant’s flowering phase.
While most people still prefer to grow their plants in an actual garden, growing plants indoors has its own benefits, especially when the weather is bad. If you want to have an indoor garden instead of the usual outdoor one, then you’d know that one of the most important pieces of equipment to have is a good grow light. If you’re pretty new to indoor gardening, our list of the best 400w hps bulb for flowering will be especially helpful.
The Importance Of A Good 400 Watt HPS Bulb For A Plant’s Flowering Stage
Now that you have an idea as to why we chose the EyeHortillux as our top pick, you may be asking yourself why is an HPS bulb good for plants in the flowering stage?
One thing to take note of is that each phase of a plant reacts differently to different lights. That’s why not all lights and heat levels are good for certain stages of growth in a plant. You have to make sure that the light you pick suits the plant and the stage it is in. The blue lights in the spectrum, in particular, are not very good for the flowering stage or the production of buds and fruits. Cool blue light spectrum is best for vegetative stage.
An HPS (high-pressure sodium) bulb, on the other hand, lacks blue light in its spectrum, so it’s good for the flowering stage. Other than that, it also emits very strong yellow light, which is very conducive for budding. This is why HPS bulbs are the most popular lights that most gardeners use whenever they want their plants to bud. Another thing about HPS bulbs is that they’re really strong. With a strong wattage of 400W, these bulbs emit a lot of heat that stimulates bud growth.

Key Features Of Our Top Pick - Eyehortilux HX66620 Super Spectrum Bulb
Optimized Spectral Energy
The optimized spectral energy allows this bulb to distribute light (across different spectrums) that is stronger than the other regular HPS lamps. This allows it to provide high heat and light for a healthy budding of the flowers. The optimized spectral energy of the HPS light allows it to have a total power that is 17% stronger than most other HPS bulbs. Also, EyeHortilux’s Optimized Spectral Energy feature promises better yields and energy savings.
Environmentally Friendly Materials
Because it’s made from environmentally friendly materials, it can be recycled and disposed of pretty easily. Unlike most of the HPS lights found on the market, EyeHortilux lamps do not contain any lead and have very low levels of mercury, making it a non-hazardous waste according to the EPA and the TCLP standard.
High Lumen Count
Lumens are used to measure the amount of visible light shown by a lightbulb. For an indoor gardening, the stronger the light, the more effective it is for the plants. The EyeHortilux Super HPS Bulb has one of the highest lumen counts on the list with a total count of 55,000, making it very strong and efficient for the budding phase.
High Color Temperature
Most of the HPS lights on the market (or on this list for that matter) all have a color temperature of 2000 K or Kelvin. The EyeHortilux HX66620 Super Spectrum Bulb takes it up a notch and offers 2100 K for its color temperature, which adds to its spectral energy and overall heat. This is why this brand of HPS light is known for emitting the most heat energy to plants.
The Pros And Cons Of HPS Grow Lights
Of course, HPS lights aren’t perfect, which is why we always mix and match HPS bulbs with other types depending on the situation. However, if you really want to go deep into indoor gardening, it’s important to know the advantages and disadvantages of using HPS lights so that you’ll know when to use it and when not to use it. You’ll also understand how effective they are for certain situations.
As you can see, the crowning factor of an HPS lamp lies in its power and heat intensity. This is why HPS lamps are a favorite to use for plants in the flowering stage, especially marijuana/cannabis.
However, we can also see that the intensity is not good for the younger stages of the plant’s life. So, HPS lamps do serve their purpose, which is to stimulate bud growth. By using HPS lamps and other types of lamps when appropriate, you’ll definitely be able to grow a healthy and robust indoor garden.
If you want to become an indoor gardener, then you have to know your equipment by heart. HPS lamps are extremely important to the growth of your indoor plants because they need the right amount of heat and light, especially in certain stages of their growth.
