Celery's ok but it's not very nutritious. I use collard greens, kale, bell pepper, carrots, butternut squash and other fresh leafy greens along with a good dry gutload such as Cricket Crack.
yea i have been keeping the kale in there for them and some cricket food i was just wandering if it would be a good thing to gut load with, lol doesnt mater i went to put it in there earlier and my stupid fridge had frozn it, thanks tho jannb
