CEC is a HUGE subject and one which I am only qualified to briefly discuss. So I'll wait around for an expert on that. So what I've been able to glean from this discussion is that, in an organically prepared soil, using only organic materials as it pertains to nutrition and additives and no flush is necessary.
Now, if the 30 gallon LK containerized plants have the exact same mix in them, including some of the native soil which I always put into my containers as an innoculant...I shouldn't need to flush. BUT, okay I think this will help: I have two LKs in the exact same containers, soil, and were watered and fertilized at exactly the same time in the same sun exposure. One of them will get the royal flush treatment, the other not. Let's see what happens. What's the worst that can happen? Harsh smoke? I'll still wash both plants before drying and curing.
I have a plan in my mind. One thing I'll say, the LKs definitely smell lemony out there. The plants have not started to stink up yet. I hope that comes soon.
This is a great discussion which I hope will continue. Let's get out books and websites and dig into CEC (cation exchange capacity) like this was a 3 credit course! I'm in. Let's understand it so well we can explain it to a scientist.
