5 Things to Consider When Buying a Growlight

Coverage Area

We like to start off with the area you want to cover. If it’s a small area in a small room, it will require a different light than a large coverage area in a large room. Industry standard usually comes to a 4’x4’ coverage area, so many lights are created with optics to hit that area perfectly. We test how many of these lights hit their suggested coverage area and often have our own opinion. Check out each review to see how many lights cover your grow.

If you’re looking for a small setup of around 2’x2’ with little heat we recommend the Platinum LED.

If you’re looking for a light that has great coverage area with a low price and heat is no worry, we recommend a Gavita 1000w DE.

Bulb Life

This variable is important for you to understand your reoccurring costs and how much labor is required. The serviceability of bulbs should also be considered when purchasing fixtures. HPS and metal halide fixtures are fairly modular and easily serviced but have to be changed annually. LEDs on the other hand have a positive that they last 10x longer than HPS, but the downside being they are far more difficult to service.

Vegetative or Flowering

These are the two stages of growth for plants. All plants start in a vegetative state that prefers a blue spectrum, enabling leaves to spread and branches to gain strength. You can use metal halide, plasma, T5, induction, or LED fixtures for this phase of plant growth. Once ready to turn your plant to flower or fruiting, you want a spectrum that is redder in color. These fixtures are usually HPS, plasma, or some LEDs these days.


The amount of watts gives good perspective on the efficiency of the light fixture. For a 600w replacement, we look for 250w-350w of LED or plasma such as the Diamond LED. Energy efficient lighting fixtures built to replace a 1000w fixture usually pull 520w-650w. The Heliospectra is a good replacements for 1000w HPS fixtures such as the Gavita.


LEDs have given the horticultural industry knowledge on what every wavelength of the spectrum does. Another blog post we did sheds more light on the benefit of a full spectrum.
