Anywhere from 97% to 99.5% of the water taken up by the roots of a plant ends up being released back into the air. During this process, a physical change in the state, or phase, of water occurs—from liquid water to water vapor. Implementing a watering system that uses less water on average effectively reduces the amount of water getting into the plants between 50% and 60%, which in turn reduces the overall amount of latent heat in the system. By reducing the amount of latent heat by 50% reduces the total heat of an air conditioning system by as much as 25%.
With real-time moisture monitoring and responsive, moment-to-moment water supply, irrigation becomes an opportunity to let plants self-regulate in response to air conditions.
All growers fear the crippling results of under-watering your plants, but can the true killer be over-watering. This article discusses the proper ways to achieving beautiful perfect plants in regards to air, water, and the different irrigation methods to achieve just this.
Every cannabis grower knows the perils of improper watering. And most can recall a time or two when they damaged the health of one of their girls through an overzealous watering schedule (or simple forgetfulness). But few recognize the epidemic of ongoing, low-level overwatering – both in at-home amateur grows and larger, automated operations.

All growers have done it: damaged a plant with erratic watering practices. But for cannabis cultivators, the compromised health of just one or two prized plants can significantly impact the bottom line. Experienced growers rarely let dehydration occur, and larger greenhouse grows incorporate systems that all but guarantee underwatering doesn’t happen. Yet the painful memories and guilt of underwatering persist in the minds of even the best cultivators and sometimes lead to the less recognizable sin of continual, low-level overwatering.
