When it comes to LED grow lights, the most expensive lights are not always the best. It’s always good to get a light that balances price, wattage, and coverage. Two other important things to consider are the lifespan and user ratings. If a light is rated very highly by numerous users, you can be sure it is of high quality. One light that balances all the above-mentioned features is the Mars Hydro 720W Full Spectrum LED Grow Light. It is very well rated by indoor growers and has a lifespan of 50,000 hours. If you’re growing 12 big plants that require 25 watts each, this light will give them all the light they need.
