There are several factors that determine the amount of water a POD uses such as plant variety. We estimate 1,600 gallons per day usage on average per POD. A standard residential volume of 6 to12 gallons per minute provides 8,000 to 16,000 gallons per day which is adequate to operate a POD.
Plant use (2% of pumped irrigation or 80GPH @ 10 hours per day (2 hours on 2 hours off) or 800G per day, which doubles for washing grow towers etc. to reach a total of 1,600G per day. The irrigation system circulates 1,020 GPH per POD; (2 to 2.5 GPH per tower for 1,600 towers with 2% system use/loss = 4,080 GPH/2 = 2,040 GPH per POD) should all towers be watered at the same time.
