Separate four questions: what area is planted, what depth or volume you are considering, what the equipment delivers, and what the soil actually needs. The calculator answers the unit-conversion question. Observations and locally suitable guidance answer the others.
What’s worth understanding
Ventilation, crop cover and growing conditions change tunnel water use. A fixed schedule can over- or under-irrigate.
Take it into your growing space
- 1
Measure the planted area, not the entire property.
- 2
Measure or check actual equipment output.
- 3
Compare root-zone moisture before and after a known application.
Use this explanation to ask better site-specific questions, not as a diagnosis or a universal planting prescription.
