Combining Single Spectrum LED Lamps

March 2, 2019

You can use LED lamps that produce a single spectrum of light, and LED fixtures also come in varying combinations of single spectrums. Some even offer the option within the same fixture to switch from blue only to red only, or to run them together, when you want to shift from vegetative to flowering.

This grow tent blends blue and red light together for growing plants start to finish.
