What Is the Actual Flowering Time for Purple Sunset Autoflower?Updated a day ago

The listed timeline for Purple Sunset Autoflower is typically 8 to 10 weeks from sprout to harvest, but real-world results may vary slightly depending on growing conditions.

In the product description, you'll see an estimate of 8–10 weeks, which reflects the average cycle under optimal conditions. In the video featuring Kyle Kushman, a longer estimate of 10–12 weeks is mentioned to account for:

• Environmental variables

• Lighting differences (indoor vs. outdoor)

• Slower development due to stress, transplanting, or inconsistent care

• Phenotypic variation from plant to plant

Which Timeline Should You Follow?

Both are correct — they represent a range of expectations based on grower experience:

• 8–10 weeks = possible under dialed-in indoor conditions with strong lighting and stable inputs

• 10–12 weeks = more realistic for outdoor setups, less-than-ideal conditions, or growers seeking full trichome maturity before harvest

What to Watch Instead of the Calendar

Instead of harvesting strictly by the week count, monitor the trichome development using a jeweler’s loupe or handheld microscope:

• Clear trichomes = not ready

• Cloudy/milky trichomes = peak THC

• Amber trichomes = more sedative effects

This method gives the most accurate picture of when your Purple Sunset Auto is truly ready for harvest.
