LED grow lighting has many advantages over high-pressure sodium, metal halide, and fluorescents – they use less energy, emit less heat, reduce water usage and have spectra that are optimized for plant growth. Another great thing about LEDs is their reliability. Instead of re-lamping every year, many LEDs have lifespans of 10 years or longer. But as more growers transition to LED grow lighting, more questions and concerns arise.
For decades cannabis growers have been honing their grow “recipes” on their own and when the light technology “ingredient” changes so do the other variables like nutrient uptake, temperature, humidity requirements and so on. Implementing LEDs into an already dialed in grow can be challenging so let’s look at the first step to make this a successful transition:
