I use flora series nutrient, and I mix it at 10mL per gallon of each.

5 mL per tsp
15 mL per tbs
1 cup (8oz) is 237mL
16 cups in a gallon = 3792mL per gallon
3792 divided by 10 (mL per gallon) = 379.2
Or simply 380 gallons of nutrient solution I get from buying the one gallon containers of the liquid.

tsb is a volume measurement, and 1.5 pounds is a weight, so there is no way to do a comparison without knowing the density. That's probably the reason the retailer wasn't able to help me figure it out. Assuming it has the same density (weight) as sugar and the conversion is correct, those figures might indeed be correct. But How do you get 2304 gallons of nutrient solution out of 3792 mL of concentrate? That is less than 2 mL per gallon in the nutrient selution. Are you using the FLORANOVA series? If so it's about 3 times as expensive as the flora series, at about $85 x3= $255. it males more but it is not under $100 for all 3 anywhere I know of.
