LED lights have become increasingly popular for hydroponic growing in recent years. They are available from numerous online retailers, such as Dorm Grow. LED lights offer a number of distinct, compelling advantages over incandescent and compact fluorescent lighting (CFL) bulbs when it comes to indoor plant cultivation.
These advantages include dramatically lower energy consumption and a much lower heat signature. Like any methodology, though, knowing how to grow successfully with LED lights takes knowledge and a bit of trial and error. The following tips will help you get up to speed with this exciting lighting option.
Distance is Important
It is essential that your LED grow lights are mounted at the correct distance from your plants. Either too close or too far away will make successful growth all but impossible. As one would expect, the more intense a given light, the further you should keep it from the top of your plants. For instance, a relatively small, low-power 240 watt light should typically be positioned about 16 to 30 inches above the plants.
A 450 watt light should be kept at a distance of 20 to 30 inches. A 600 watt light should be elevated about 24 to 34 inches. Finally, a very large and intense 900 watt light needs at least 26 to 42 inches of clearance to avoid over-saturating your plants with radiation.

Don’t Over Water
LED indoor grow lights produce dramatically less heat then conventional lights. This means that they won’t dry out the soil nearly as quickly. Consequently, the volume and frequency of watering should be scaled back considerably. This can take some getting used to for experienced growers, as it will probably feel like you’re not giving your plants sufficient water at first. Just be sure to remember that too much water is as bad as too little.
With a bit of time and practice, you’ll begin to develop a feel for how much water is required. Until your intuition adjusts, though, err on the side of caution. Wait until your soil feels mostly dry before adding more water.
Use a Power Stabilizer
Your LED grow lights are an investment. While they can easily last a very long time, it is important that you take care of them. Fluctuations in the amount of power delivered by your building’s electrical system can potentially damage your lights. A power stabilizer — also known as a surge protector — will prevent this from happening.
