The Public Utilities Commission has proposed a requirement that all indoor cultivation operations use only LED lights by 2023. This allots a 3 year period for California’s 3.4 million square feet of indoor cultivation facilities to completely switch over. Cultivators have pushed back, expressing that this regulation would be excessive considering the standing environmental regulations they already must comply with. The push back is warranted, considering LED lights typically cost up to $90 more than traditional HPS lighting. The situation is still unfolding, but it’s clear there is a major sustainability issue, and any solution will require major buy in from all parties.
