i got a few media question. 1)Is it better to make your own media or buy it? 2)Which is better for the frogs? 3)a 4 liter bag of ED's Super Instant Enhanced Fruit Fly Media is $29, how much would it (roughly/est) cost to make 4 liters of home made media with mold inhibitor? 4) on ED's site is says "Add 1/3 cup of media and ½ cup of hot water, swirl to mix, let cool. Add 1/16 teaspoon of bakers yeast and flies." are you adding all of that directly into the deli cup or a pot then pouring it into the deli cup?
