Indoors i tend to avoid applying Alf to my growing medium since even it's crude form it is highly concentrated and it's rapid decomposition has a tendency to lead to pH fluctuations. I have used Alf in planting mixtures used for outdoors to help condition the soils, but these days i tend to choose better locations with optimal fertility and so this practice is no longer necessary for me. When Alfalfa is applied as a component of a 'tea' at concentrations generally in the order of 1:250 or 4% it serves as a ideal source of organic fertilizer for vegetating plants worm farms are also a essential part of organic farming - there are many advantages to worms in your medium.. Worm castings for one.
I agree that there be no requirement for flushing when using a biological approach to cultivation and doing so could do harm to essential bio-cultures and alter the soil chemistry, but it seems plausable to me that there is perhaps a chelation rate associated with the assistance of micro-cultures - in particular the Mycorrihizal and yeast colonies that if interupted shortly before harvest could lead to cation exchange and leeching of absorbants from plant tissues. Perhaps we could perform a controlled experiement to see if those flushed produced a smoother smoke? We could take a branch or two of a fully matured plant initially. Then Flush the media and allow a couple days to pass for leaching, then harvesting the rest of the plant and compare the smoke two months later? Also are you starving/stressing plants before harvest to increase trichome production? Hope you don't mind me asking so many questions..
