Q.watering tomato\’s

Zone 92807 | roka added on April 8, 2018 | Answered

I keep reading posts (including yours) that talk about watering 1-2 inches but water is not measured in inches. It’s measured in gallons and usually in gallons per hour (especially when watering by drip irrigation). Besides, measuring in inches tells you nothing if you don’t know the diameter of the watering area. Can you help clarify this?

The full measurement is that an inch equals 623 gallons per 1,000 square feet, 62.3 gallons per 100 square feet, 6.23 gallons per 10 square feet, and so on.

Upon further reading I saw that each tomato plan needs approx. 7 gallons of water per week. This seems like a lot more than your 6.23 gallons per 10 sq. feet (about 3x as much). Can you explain this?
Also, is the 6.23 a weekly figure?
