Hydroton; liters in a gallon?

Quick question if anyone could help me out, trying to fill 12 2 gallon pots with hydroton, how many bags do I need? 3.785 liters in a gallon so 3.785x12=90.84 liters. So 2 50 liter bags should be sufficient or am I figuring this wrong? Idk, I'm ripped and it's a hr n half trip, want to make sure I got enough without wasting money I don't need too.

4x12=48. U got bad math skills. One bag.

Must not have had this guy for a teacher on grammar school

Wow..ya both missed it lol! 12x2(gal. pots) =24(gallons).. still with me?? We'll call it 4l/gallon, 24(gallons)x 4(l/g)= 96liters, so YES 2 50l bags! Wish I was that ripped lol

I got it.lol. just correcting his math, but yes two bags.
