How the grow calculator works

Enter the start date into the calculator. This is the day the seedling emerged from the substrate. After clicking the “Calculate grow day and grow week” button, the calculator shows how many days have passed and which grow week the plant is currently in.

If you no longer remember the exact date, check whether you took a photo or review when you ordered your growing equipment or seeds.

2) BONUS Grow calculator (forward planning) ⏩

As a complement to the calculator above, you can access a non-binding timeline preview for a self-flowering plant here. If you start today, the tool provides an estimate of your plant’s development.
