Very seldom have i needed to change the water on the veg side
It sure is easier than i was lead to believe when i first started.
Some stress training is good thing imo. How much is too much? This plant can take alot.
ROOTS. How much water volume do these roots displace?
Just looking and guessing how much? I would always think maybe 3 gallons
last grow doing my bro science studies i think i discovered that its not near what one would think.
Nothing scientific but at the end of my grow last time, i measured the depth of the water in the system and removed 2 root balls from their modules and added the water back using a pail.
What i found was that each root ball didn't even displace a gallon of water each. The math worked out to 8% of the total water in the system was displaced by each plant. Again bro science and it needs verified. I'd be interested in others findings.
Sorry Zen, no pictures.
