EDIT:
I'm into the whole water thing as well. So my experiment was in a hydro setup. Not sure if you into dirt but I know that in water it I can taste chemical if not flushed. All I ever do is just swap to plain water last 14 days and WOW!!!
That's weird, I did that experiment with white widow and had a FEW ppl try it. Gave them A and B and then told them to tell me which smoke had chemical taste. Every last person INCLUDING myself could tell off the rip which had been flushed. I mean IDK but I did EVERTHING the same on all the girls just left one with nutes all the way thru but she was choped, hung, dried and cured EXACTLY the same way.
Then again SD is my FAVORITE strain in the world (to date, could change) and I know that it's such a TASTY smoke so maybe the fact that SD has such a amazing taste it has ability to mask other taste. Being serious too, cause I have since got another WW strain that is MUCH tastier then the one I did test with. SO that said, maybe stronger tasting strains mask that nasty chemical taste I hate ever so much.
I thought my experiment was conclusive BUT I now see that I have to try it again with a better strain then the one I chose last time. Another round of Orange Kush is up in a bit. Might try it with that and see what comes of it. I'll see if I find this thread when I am done with round two of this experiment and post my findings!
