1) Buy or make--that's a personal preference. I have always made my own (except when I was able to bring some of the Carolina mix home from the lab), and found it to be as good or better than the Carolina mix . . . and lots cheaper. My media is super simple and effective for me.
2) Unless the media is vitamin/mineral fortified, it doesn't matter to your frogs whether you bought or made the fly media.
3) Several people swear by Ed's, but I haven't used it. I use 2 cups instant mashed potato flakes, 1/4 cup brewer's yeast, and 1 cup sugar. That's mixed up in a 1 gallon Ziploc, and I just dip it out as I need it. The dry goods go directly in the deli cup (or quart mason jar), and I mix it up with a solution of 1/2 H20, 1/2 distilled white vinegar until the proper consistency is reached (the vinegar=acetic acid, and is the mold inhibitor--does the same thing as propionic acid or whatever other mold inhibitor you would consider). Then I sprinkle on some active baker's yeast and throw in a folded coffee filter for the flies to crawl on. Price it out, but the most expensive part is the brewer's yeast (about $8/lb). Personally, I'm set for the year on about $10-$12 worth of supplies (I don't count vinegar or sugar as an expense, because we always have it on hand). But, then again, I only have about 4-6 cultures going at any given time right now.
4) Mix it up in the cup. You don't waste mix that way, and it's not as messy.
Hope this helps.
: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?
:thanks in advance!
