What type of LEDs are used for grow LED lights? Answered
I've been googleing about the advantage of LED grow lights and how it saves energy and how they last longer. After looking to buy them I realized they were very expensive. However, I also found a few do-it-yourself guides which I thought were pretty neat and straight forward. The only thing I didn't see was if the LEDs they used were special or just any red/blue led lights can be used. Hope to get an answer and save a few bucks but most importantly save energy, Thanks in advance !!
