Wet hops are 80% water, 20% vegetal material.
Commercially Dried hops have 8-10% moisture, use 10% to keep the math simple, so 90% vegetal material.
To get the same amount of vegetal material (Lublin and oils), 90/20=4.5 times as much wet as dry. To get the full fresh hop aroma, use 5 or 6 times, because you can!
