Far as I know organics are basically flush free. I have done it all really... Not Flushed, One week Flush, Two week flush. I'm totally organic from nutes to soil and I've never tasted the difference. I've even taken from the plant early - quick dried in the oven -- rolled a doobie and every time I get pure white ash and everything burns evenly. Also it was never harsh or burned my throat. So it's really up to you. There's nothing wrong with flushing it. I just think from personal experience and other organic growers experiences you don't really HAVE to flush with organics. But, I say again it's really up to you the grower. Looking forward to the smoke report Bud! I've wanted to grow some AutoWidow for a while now! Can't wait to hear how you like it!
