MasterTooner, good evening 2U... I also have done this procedure
with the bucket levels and have discovered the efforts
are not worth the benefits. If i may pilot ! !
I have found, if one flushes the hydroton, by pouring pH treated water
into the hydroton buckets on a regular basis, after a couple of flushes, which can be done in one setting / flushing, that now the extra clean water seating in the liner buckets is actually beneficial to the plants health. There's something uniquely inherent, to this growing medium ( hydroton ! ) that does not allow rot out of the root system.... if the water is flushed on a regular schedule ! So, we hydroton users, have to check the roots, on a regular bases, til, we get a " feel " for the tolerance, or balance between plants,
nuitrients and water.

Personally, I've loved the experience so far. Um-a - first-timer with this
hydroton ebby & fafaflouey system and there are lessons at every turn. A total evolution of the entire hydro-grow system the G-Room is self, as one learns and grows from our rewards of our passions!
