Just a little tid bit of information, to show one of the reasons why indoor growing is better and financially smarter than outdoor growing in the long-term:
Indoor growing uses less water than out outdoor growing and greenhouses.
From Surna's website:
"It is estimated to take 6 gallons of water per day per plant.
It is possible to save water when growing indoors due to water reclamation, which is not possible when growing outdoors or in greenhouses. All water not directly consumed by the plant eventually makes its way into the air as humidity. In indoor cultivation, it is possible to collect condensate pulled from the air and reuse the water, which is not possible when growing outdoors or in greenhouses. This ability to collect condensate and reuse the water means growing indoors requires less water than other growing styles."
