Whether you’re raising a rare species flower or simply growing herbs and greens for the dinner table, LED grow lights can help you cultivate a variety of plants indoors.

Growing indoors gives you several advantages over outdoor gardening. The most obvious is that you can better control the temperature. Most plants will have a narrow range of temperatures under which they will produce blooms or fruit.

Another factor you can control in an indoor growing environment is the humidity level. While some plants love moist, humid air, others are prone to disease under those same conditions. Alternatively, many succulents and cacti prefer a dry environment, which you can provide in an air-conditioned space.

Outdoor gardening, however, has one distinct advantage over indoor gardening, and that’s a surplus of the necessary sunlight that so many plants require to thrive.

Fortunately, LED grow lights can provide all the light your plants need -- efficiently and inexpensively.

What distance should a grow light be from my plants?

In general, plants will need to be within a couple feet of a grow light to get any benefits. The closer a light is to the plant, the higher the light intensity is.

The distance also really depends on the strength & type of light you’re using. If you’re worried, I would suggest starting off further away and bringing the light closer to see how your plants respond.

Generally, the closer a light is to a plant, the less width it covers. So if you’re only after lighting a single plant, you can put the light closer to the plant (which means more light for the plant).

If you’re lighting a few plants, consider the span of the bulb. You may need to have the grow light further away to cover multiple plants. Keep in mind that the further the grow light is from the plants, the less light they’ll receive.

Set up a Timer

Power strips can cost 10-15 dollars on average. However, this simple timer can save you hundreds. Plants need varying amounts of sunlight per day. Too much can kill the plant and your electricity bill. If you forget easily, this is a necessity.

How long should a grow light be left on?

How long a grow light should be on for really depends on a few factors. They include the particular light you’re using, the environment your plant is in and what you’re using the light for (eg, foliage growth, vegetables or flowering).

The light you use should come with specific instructions. But as a general guide, here’s a few tips.

  • To be effective, grow lights really need to be on for at least 8-10 hours a day. This can vary up to 16 hours, depending on the conditions. That’s why LED grow lights are so popular – when they have to be left on all day, it’s best to use an energy efficient type!
  • Always position a grow light above the plant. This replicates sunlight. Plants will naturally start to lean towards a light source, so above is always the best choice.
  • If your grow light heats up, make sure it’s not touching plants or getting too close to them.
  • Young or shade loving plants can get away with less powerful grow lights, whereas large plants and ones with big leaves that can absorb lots of light (eg Fiddle Leaf Figs) can love the benefits of a stronger light.
