Do these LEDs, tuned to the light temperature most beneficial to plants, give off that purple cast into the room? I have seen the ones in my local hydroponic shop and the light they throw out is most irritating.
Buy a (Made in China, yay!!) LED controller for < $10 and you can make the cheap LED strips emit any color you wish. Some have white LEDs interspersed with the RGB (color) ones so you can have a mix of all-spectrum and specific colors at the same time. Plants ought to love that. LEDs also emit UV but check the specs as this varies.
One potential side-effect (benefit?) from LED lighting is that it’s so much more efficient that you can probably put in a lot of LED grow lights withough making a big enough increase in your electric bill to raise any eyebrows. In the past with traditional power-hungry lighting, a high electric bill was a tip-off for authorities to do a little more investigation.
Not surprisingly, if you google “LED grow light” a cannabis-related hit is #3 on the list.
