Using Jane responsibly.

Jane is a nutrient calculator and garden timing tool. The current browser app is being tested by invitation for saved-account tiers; Free is available without an account.

Check before mixing

Amounts depend on the selected chart, units and water amount. Check product identity and manufacturer directions. Manufacturer schedules may be adapted to the selected duration. Bottle colors are label-inspired visual cues, not product packaging, concentration or dosage instructions. Measure and verify pH as you mix.

Reminders and saved information

Browser reminders need permission and a running page. Device sleep, browser suspension or denied permission can interrupt them. Do not rely on a reminder as the sole record of when action is needed. Saved accounts and local test data behave differently; website privacy choices do not erase app records.

Independent service

Manufacturer names and trademarks belong to their owners. A listing or chart does not imply endorsement, partnership or manufacturer approval of Jane’s adaptations. No crop result is guaranteed. Use the service lawfully and follow safe product handling.
