That theory would work. Based upon common logic indeed.

But the million dollat question is not what is the bottom or dry weight, but also, what is the completely saturated water weight?

And I assume you could test as you should need to add the EXACT same amount of water each time...assuming the low weight was the same....

However, did you fail to take into consideration the weight of the added foilage, stems and roots?

If empty with real small roots, your weight will be mostly soil


But....if later on, say your roots quadruple in size and girth.....the same low weight would now be DRIER roots.

I know we're talking ounces here, but at 8# a gallon, it doesnt take much....

I'd up the the water requirement LOW WEIGHT every few days by say a .25 ounce maybe???

Sorry man but im high and theat was good convo

Enjoyed it...hope it made snese.
