Cannabis is an annual, and I believe that if you are doing it right the roots never stop growing.
I've been gardening organically outside most of my life. If you have the ability to do full organic for your plants in a stealth environment, then I envy and commend you.

I have never been lazy nor cheap, but I do draw the line at "make work". My tap is consistently in the correct range, so I don't pH it to flush. In my situation, adjusting is make work. I also believe that foliar feeding is make work, but I don't bust people for doing it. To each his own.

I haven't used the Clearex yet but when I do, I'll be using caution. I understand that it is nothing but a chelating agent that locks up any remaining nutes in your soil. Do you know something about it that we need to know?

BTW, aren't the commercial preparations of pHUp and pHDown "chemicals"?
crabbyback Reviewed by crabbyback on . i know I should know this.... I'm wondering how to go about a pre-harvest flush for my girlz. I've had a number of sucessful harvests already using a hydro set up. In hydro I do a four day "flush" ,changing the solution daily, or if possible twice daily. Strains in this harvest are : Big Buddah Cheeze and Power plant. They both list their grow period as 8-9 weeks. Over the course of growing hydro (cool temps) I've found my harvest window to be consistently 60-63 days. Now, this is the first run of using a soil Rating: 5
