Here are the most recent ,that Get Up & Grow are aware of, Led’s available on market . The design is well thought out by of course hands on horticulturists.
Led’s will not effect ambient temperature of Grow Spaces much in comparison etc. It is also said Plants are not stressed by whole effect thus giving more flower for less power. The actual harvest should keep the natural characteristics , flavors aromas more present then other methods , Of course everyone knows you cant beat the actual Sun for raw energy , that is when it comes out.
