Buying the Best HPS Grow Lights for Your Garden

If you are new to purchasing a light bulb for growing, HPS bulbs can be your next friend. However, as a starter, it can get confusing on which kind should you purchase. To help you out, here’s a quick buying guide and a few FAQs for you.

HPS light bulbs are set up in a certain distance away from the plants themselves

  • Are HPS bulbs worth it?

If you are trying to grow plants indoors, mimicking the sun’s light and energy is best done by HPS bulbs, which is considered as the best light bulb to grow plants and herbs. It gives consistent and predictable growth yield as compared to normal light bulb.

  • Wattage is essential.

HPS bulbs can range from 150-1000 watts. To get the best results, here is a quick guideline to follow:

  • 150w bulbs don’t get hot easily and are only best for 1.5’x1.5’ bed area;
  • 250w bulbs may get hot significantly, thus needing ventilation and are only best for 2.5’x2.5’ bed area;
  • 400w bulbs are best for getting productive rather than maintaining and are best for 3.5’x3.5’ bed area;
  • 600w bulbs have the least relative waste and are best for 4.5’x4.5’ bed area;
  • Lastly, 1000w bulbs are the most productive but the most expensive and best for 6’x6’ bed area.
  • A ballast is very important.

Without a ballast for your HPS bulb, you may increase rates of explosion and damage. Ballasts help power up your bulbs and regulate the voltage and energy at optimal frequencies.

  • Should I entertain spectrum output?

Absolutely, it is highly important to know the spectrum output of your HPS light bulb. Depending on your plant, it requires a certain spectrum in order to grow healthy to your specific standards. By ignoring the spectrum output, you are technically wasting money and time by carelessly putting light bulbs randomly.
