Does watwr amount actually matter?

I may be completely UNDER thinking this, but I'm thinking in terms of ratios and it makes sense to me.

Say you had a 15 gallon storage tote converted into DWC system. .
3 6inch cut outs to hoke 3 plants.

Now you think 3 plants, 15 gallons, 5 gallons per plant.
But in reality you can't put nearly 15 gals in that reservoir because they're on the longer side, not the taller side, so roots will quickly touch the bottom- therefor keeping the water pretty low, to encourage the shorter roots to keep growing down.

What do you guys think of running 5 gallons for all three plants?
The nutrient concentration would be the same as it would be in 15 gallons of water because you just adjust nutrient solution based on water amount.

So no harm no foul, right?

Not. really, man. my guess is these are seedlings you're working with. Really it's for aerocloner with decently long roots. If you're using seedlings, you can do the same thing with an aerocloner. Bought or DIY.

I think you'd run out of water! Smaller plants will be fine but a larger plant can easily "drink" a gallon of water per day. Also the nutes would be 3x stronger. I don't know the technical talk for it, but say the root takes up an gallon of water it takes up 1 oz of the nutrients in that water. But if you have same amount of nutes in 5 gallons then per gallon of water taken up would be 3 oz of nutes. Since it will drink a gallon a day it's getting 3 oz of nutes instead of 1 oz..

Less water volume equals greater pH fluctuation and difficulty keeping PPM inline.
