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. Some of the benefits of properly flushed weed: 1. Taste/Smell. 2. It burns better, and has an overall smoother smoke, and is not as harsh on the lungs. 3. It's much healthier. 4. It will save you money! Nutrient solutions are not free. --Puffaluffagus
I totally agree with the info here. Have you ever tried organic growing in all your years of experience? It cuts out the need to flush all together and makes for a healthier, better tasting and better burning product all around. My first couple grows were half assed organic, then I went to chem nutes, and now I'm back to organic again. It's a lot to learn but so worth it. With super soils your plants can be water only the whole grow and get a full season of flush!
