HPS lamps, sometimes referred to as high pressure sodium lamps, are a type of fluorescent growing light, which emit high levels of light with a color temperature of approximately 3000K.

HPS lamps have many benefits over other types of grow lamps because they produce a large amount of usable light while maximizing lumens per watt. In other words, HPS bulbs will consume less electricity than other forms of lighting while producing the same level of usable lighting for your plants.

HPS bulbs are an excellent choice for most indoor grow operations because they simulate the natural light spectrum, which generally leads to a higher quality and higher yield of plants. Also, since the light spectrum is similar to natural sunlight, the plants will remain healthy and develop a good structure with good roots and strong stems.

Now, you probably already know that HPS grow lamps are a staple in the indoor growing world, but you may not fully understand how you can best utilize them.

The best way to use these steady devices is to install them at a height of 30 inches from the tops of the plants. You can achieve this using any type of sturdy stand, such as a decorative lantern, an aquarium stand, or even a milk crate.

Frequently Asked Questions (FAQ)

What's the best HPS grow bulb?

When looking for the best HPS grow bulb, the light spectrum is the most essential thing to consider. Ideally the bulb should cover the full spectrum range visible to the human eye. But apart from that, ensure that the bulb has a good light intensity rating. For a pre-made HPS grow light system, overall cost should also be factored in because bulbs cost more if they are included. That’s why I have also suggested the best options as individual bulbs.

What is better for growing LED or HPS?

Although commercial and professional grow-lights may have more robust components, they are expensive. Instead of buying a new grow light for your garden, consider using a high-quality LED bulb. They use 80-85% less energy, last 25 times longer, have a higher light intensity, and emit light at a more natural daylight spectrum. LEDs also have the added benefit of making your garden greener. Yes, that’s right, green (and not just because it’s weed free).

What's better for veg HPS or MH?

The answer to this question really depends on your specific application. MH is more effective for growing leafy and root veggies, while HPS are great for fruiting veggies that require more flowering. Some plants do do well with both types of bulbs. These are the most commonly used in gardens: HPS light bulbs (>300W) for vegetative growth; MH light bulbs (<300W) for flowering and fruiting.

What is the best 600 watt HPS grow light?

These lamps are used by commercial growers and horticultural scientists to produce high yields of plants like tomatoes, peppers, cucumbers, and fruits.

The best 600W HPS lights deliver full spectrum light including UV light. This makes them ideal for the growth of fruiting plants including vegetables, herbs, and flowers.

Be sure to get a full spectrum grow lamp for your home garden since it will eliminate the need for additional lighting. And it’s a smart investment since it typically lasts longer than other HPS bulbs.

Note: Because this lamp produces high levels of heat, it’s essential to use a sturdy lamp stand and fan. Always use extra protection when working with this lamp.

Conclusion

This is a decision not to be taken lightly. The best HPS bulb for your garden should look the part, flame beautifully, be easy to trim and come with a great warranty. In our experience, the best bulb to achieve all of these requirements is the American Hydroponics 24W DE lamp. It may not be the cheapest out there, but the quality is outstanding and it’s a name you can rely on.
