What Do “Growth Cycle,” “Flowering Time,” and “Veg Time” Mean? 🌱⏱️Updated 22 days ago
We know the timing information on seed listings can sometimes feel confusing — especially when you see things like:
Total Growth Cycle: 77 days
Flowering Time: 9–11 weeks
Those numbers can look like they’re describing the same thing, so here’s what each one is meant to tell you.
Total Growth Cycle 🌿
The total growth cycle is an estimate of how long the plant may take from the early growth stage all the way through harvest.
For autoflowers, this is often described as seed-to-harvest time.
So, if an auto lists a total growth cycle of around 77 days, think of that as an estimated overall timeline — not a guaranteed harvest date.
Flowering Time 🌸
Flowering time refers to the portion of the plant’s life when it is actively developing flowers.
With photoperiod plants, this is easier to separate because the grower usually controls when flowering begins by changing the light schedule.
Autoflowers are a little different.
Autos begin flowering based mainly on age rather than a change to 12/12 lighting, so the transition from vegetative growth into flowering can be gradual. Because of that, flowering estimates and total-cycle estimates can sometimes appear to overlap.
What About Veg Time?
For autoflowers, you may not always see a separate vegetative time listed.
That’s because an auto doesn’t have a fixed veg period that the grower chooses. Many begin transitioning toward flower after roughly 3–5 weeks, but each plant can move at its own pace.
With photoperiod plants, veg time is much more flexible. You can keep the plant in vegetative growth longer before switching the light schedule to flowering.
Why Don’t the Numbers Always Match Exactly? 🤔
All grow times should be treated as estimates rather than deadlines.
Two seeds from the same strain can finish at different times, even when grown side by side.
Timing can be affected by things like:
Individual phenotype
Lighting
Temperature
Root space
Watering
Nutrients
Plant stress
Overall growing environment
One plant might finish in 10 weeks while another takes 12 or 13. That kind of variation can be completely normal.
Why Are Some Strain Pages Different?
You may notice that one strain lists total growth time, another lists flowering time, and another includes both.
The available timing information can vary depending on the strain and the breeding information available for that variety.
We understand that having the same terminology across every strain makes comparing them much easier, so when you see multiple timing figures, use them as a general window rather than an exact calendar. 📅
The Easy Way to Read It 🌱
For autoflowers:
Total Growth Cycle = approximate seed-to-harvest timeline
Flowering Time = approximate time spent transitioning into and producing flowers
Veg Time = usually short and not always listed separately
For photoperiod plants:
Veg Time = mostly controlled by the grower
Flowering Time = estimated time after flowering begins
Total Growth Cycle = depends heavily on how long you choose to veg the plant
Most importantly…
Don’t harvest just because the number of days on the strain page has passed. 👀
Use the listed timeline as a guide and let the plant tell you when it’s ready. Flower development, pistils, and trichome maturity are much better indicators than simply counting days on the calendar.
