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...
