So this thread caught my attention, and I definitely see the benefit of removing excess salts from your growing medium towards the end of, or after your grow…..if you’re using bottled nutrients. That being said I don’t think it works on the actual plant material like a lot of people might think. It’s more for the benefit of the soil and if it is reused , and what is grown in it next. I’m not an expert, scientist or even trying to tell anyone what to do personally…..it’s just my opinion. But interestingly enough I don’t flush my soil because I’m growing with dry amendments, earthworm castings, peat moss and perlite. I’m not adding any salt based nutrients so no need to flush. I started doing this after watching this video with Kyle Kushman, where he explained why he grows organic. He says something to the effect that when the plant takes in organic nitrogen available to it, it will have nitrogen in it in molecular form up until combustion. When the plant takes up ammoniacal nitrogen that, that compound stays in the plant until combustion. He says that the temperature at which point that ammoniacal nitrogen combust is much hotter than plain old nitrogen. Okay again not a scientist but the host of the video chimes in and mentions that they personally stopped smoking non organic weed because of sore throats after smoking a few times each day. After going organic the consumption rate stayed the same but the sore throats went away. I had been experiencing the same thing. The first couple times I smoked I was fine, but by the afternoon I would get a nagging sore throat. So I slowly transitioned from using bottled nutrients to dry amendments over the past year, and the last four or five plants I grew produced a smoother smoke. I guess I went a little off subject there, but I don’t know if anyone else has any insight?
