Ask Source now tells you how much water you're going to give relative to light, for today and tomorrow.

What's new

Ask Source answers "How much water am I going to give relative to light?" for any day up to tomorrow. Past days use the measured ratio. Today and tomorrow use Irrigation Control's own irrigation plan and the radiation forecast, with an on-track verdict against the plan's target band.

Why it matters

You can check today's and tomorrow's water-to-light ratio against your own range while there is still time to adjust the strategy.

How it works

-Open Ask Source in the Source web or mobile app.

-Ask "How much water am I going to give relative to light today?" (or tomorrow). Name the cultivation if it isn't the one you have open.

-Ask Source replies with one value per day in dL/MJ, marked measured for past days or predicted for today and tomorrow, plus an on-track verdict.

-To judge against your own range, include it: "Our range is 2.2 to 2.6 dL/MJ. Am I on track for tomorrow?"

-If a day can't be predicted (for example, no current plan for it), Ask Source says so and explains why.
