LED lights are popularly used in the growing of cannabis indoors. This is because they are cost-effective and provide the greatest convenience to growers. Even LED bulbs in the best affordable LED grow lights can serve you for over 10 years without needing to be replaced, and this ends up saving you a lot of money. Other grow lights such as CFL’s need to be adjusted almost every day.

LED grow lights can be used for different wavelengths or colors. Marijuana plants require different wavelengths at every stage of growth and being able to adjust the color of the light emitted gives you greater convenience. Generally, L.E.D. lights run cooler and have higher lumen per watt compared to many other growing options.

What to Consider when Shopping for the Best Affordable LED Grow Lights

When purchasing L.E.D. lights for small amounts of cannabis, you can narrow down your search by answering the next questions.

• How Much Space do you need to Cover?

If you are only growing small amounts of cannabis, you will probably not need wide coverage of light. Knowing what amount of coverage you need is key to eliminating a lot of products, which will make your shopping easier.

The angle of dispersion also determines the area that can be covered by the L.E.D. lights. Those with greater angles of dispersion are capable of covering larger growing areas.

• PAR and Efficiency

L.E.D. lights generally have very high lumen output per watt. However, different L.E.D. light brands can have higher or lower lumen output per watt. Unlike other sources of light, wattage is not the indicator of growing power in L.E.D. lights since PAR (Photosynthetic Active Radiation) is used instead. This measures the efficiency of energy. L.E.D. bulbs with higher lumen per watt have greater energy efficiency.
