Re: The business of flies
If the flies that are available locally won't produce for a month, buy 2 now and get ready. You will find, especially when starting out the whole process will be easier if you buy pre-formed medium: Repashy, NeHerp or Josh's frogs. And make more than you think you'll need. Make them weekly, establish a schedule until you have a bit too many and get the rhythm. I make 7 cultures one week, and then 8 the next- but i have a lot of frogs. I just made 4 (which I do twice a week) and it took less than 10 minutes. Waiting for the kettle was the biggest time-suck. Some cultures may fail (but very few) and a lean week is not a huge problem- that will get rarer as you become more adept at it.
Before you know it you'll have more flies than you need, and then you'll start thinking: Hmmm, should get a couple more frogs?
And BTW: Josh's frogs can set you up and deliver quickly if you get in a pinch. Then you'll have another strain of flies. I keep 4 strains currently.
There's Bears in these here Woods. Wouldn't have it any other way.
