All my fries are now eating decap just fine. I hatch bbs ok. I use four 20 Oz Coke bottles. I do not use light or heat so it took longer to hatch. So I use all four bottles 12 hours apart and harvest at 36 hours.
If I put them in a bucket (dollar store) with 7.5W hydor heater then they hatch faster within 24 hours.
I do not have that much bbs eggs so I do not even bother to store them in the refrigerator. I am going to buy just enough to last for about 6 months so that I do not have to keep bbs eggs in the frig.
My bbs egg is about 1 year old store at RT; I think I got about 60% hatching rate (just estimate).
Where do you buy grindal worms?
