My experience
One strain
Two systems (one DWC and one Flood & Drain table)
Started flower at same time
Same room, next to each other
Same nutrients used
Difference was the table had a 180 gallon reservoir, never changed out where the DWC sites were each 20 gallon changed weekly.
Tables...
You even know what a negative ion is? Oxygen with extra electron, for a very short period. Never goes more than a few feet. Used a lot in hospital hvac. It is positive ions that have downer effects.
As fas as shitting ozone into the atmosphere, well if marijuana odor wasn't offensive or...
Only time three phase is more efficient is when primary loads are three phase devices. This generally means larger motor loads, typical to industrial applications.
Split phase is inherently better suited to the grower.
In some very large > 50 ton operations, three phase service is used for...
Note, the beefier the Ti nail, the more torching is required. My KO v1 nail takes more to heat than the thinner v2, but holds heat longer for immense dabbage, should that be required.
Leg to neutral PF if not derated, is Cosine (30) or .866
So leg to neutral max IF transformer is not a derated neutral would be 300 x 0.866 = 259.8 x 0.80 = 207.8 amps of perfectly balanced 120v
Simple math.
Leg to Leg amps is 100 x SQUARE ROOT OF 3 ( x 0.80)
100 × 1.73 × 0.80 = 138.4 amps usable leg to leg (208v)
Leg to Neutral is likely derated.
