Busting the Cannabis Flushing Myth: What Science Really Shows
Friends, after 40 years of growing cannabis and analyzing the latest research, it's time we talk about one of our community's most debated topics: flushing.
The comprehensive Rx Green Technologies study tested different flushing periods and delivered some eye-opening results. Flushed vs unflushed cannabis showed NO significant differences in:
- THC levels
- Terpene content
- Mineral content in the final product
- Taste quality in blind tests
Here's what's actually happening: When you flush, you're not "washing nutrients out" of your buds. Cannabis doesn't work that way. You're triggering the plant's natural aging process, which creates those beautiful autumn colors many of us love to see.
The truth? Flushing is a choice, not a necessity. If you enjoy the visual changes and it fits your growing style, go for it. But if you're flushing because you think it's required for quality cannabis, the science says otherwise.
What really matters for top-shelf buds:
- Proper genetics
- Optimal growing conditions
- Perfect harvest timing
- Excellent drying and curing
The cannabis community grows stronger when we base our practices on science rather than myths passed down through generations.
