Many growers these days, it seems, ignore the all-important stage of flushing their buds with pure water (no nutrients) for at least 1 week, preferably 2 weeks, before harvest. Proper flushing has numerous benefits, and results in superior quality bud (that is, if you're concerned about quality. If you're just trying to sell a bunch of crappy weed, then read no further). This is my conclusion, from over 20 years of experience growing marijuana.
Some of the benefits of properly flushed weed:
1. Taste/Smell. Pot that was flushed properly before harvest definitely has an improved taste and aroma to the smoke. Those who deny this are amateurs and hacks. The old conisseurs, like mysef, can tell quite a big difference.
2. It burns better, and has an overall smoother smoke, and is not as harsh on the lungs. Unflushed bud will crackle when burned, and burns down to black. Properly flushed bud burns down to white ash.
3. It's much healthier. Smoking nitrate salts (deposits left from all the nutrients) is NOT healthy!
4. It will save you money! Nutrient solutions are not free. Let the plant use up its nutrient reserves in the last two weeks, and just drink pure water with no ferts.
5. Many other benefits...
More growers should properly flush their crops. It would result in a lot better pot out in the marketplace. Tell all your friends and people who grow -- Please Flush your buds! Together, we can make a difference!!
