Harvest

To flush or not to flush before harvest

The flush debate, settled with what the data actually shows.

1 min read2026-05-269 views

Some growers swear by a 1–2 week pre-harvest flush. Others say it makes no measurable difference. Recent blind smoke studies and lab analyses lean toward "flushing doesn't change taste or smoothness measurably — but a steady wind-down does."

Flush vs no-flush
Flush (week 1–2 before chop)
  • Water only or very light feed
  • Plant pulls remaining stores from leaves
  • Leaves fade and yellow — classic harvest look
No-flush
  • Feed lightly until the last few days
  • Plant stays green longer
  • Less risk of starvation if you misread harvest timing
