Gainesville/Haymarket here.
Bloom does a good job in carrying some of the mustard/dandelion greens. The others -- Teeter, Wegmans, Giant -- all carry the normal stuff such as Kale, Collard Greens, escarole, etc. I tried the frozen blocks of veggies -- thawed it out, dried it and determined that its not worth the effort. But they did love the squash.
I recently switched to Dubias...crickets jump too much, and I find them all over the house, plus they smell. I can hand pick the roaches i want to feed; I can't do that with crickets. Plus the roaches are "fatter" and have a greater meat vs shell ratio than the crickets (from my online research anyway). So in theory, 10 crickets = 5 roaches (or something like that). I still do mealworms (large) and yes crickets (when I have a Petsmart coupon for freebies).
My dubia supplier is Gregs Exotics Inverts and Philly Feeders. I'm starting my own colony but still need fresh dubias.
Anyway, nice to meet everyone.
Thanks,
Dave
