When you get it right,,,,
No burn, cough (unless you get pigish), no grass smell.
Just simply smooth and enjoyable smoking.
Not just the cure, everything is a prelude to the final results.
If your getting burn & cough you're doing something not quite right.
Flushing is a handi-cap or nothing more than a band-aid that one hopes will compensate for lack of knowledge.
Spent a lot of years flushing until I learned the error of my ways.
I'll flush(?) often during the grow,, but nute to the cut.
It doesn't stop developing until a bit after the cut. So why would one want to starve the plant at the criticle end of time?
