I did that with my first batch in the 35g trash can. I figured...meh, 1/2 a bag of pellets, 1/2 a bag of wheat, 1/2 a bag of corn, 15gals of water and it'll be good.
BANHNHNHNHNH wrong. It took a while to get that cleaned up.
When unsure, start small.
Thanks for this. I finally decided to try mixing some FF tonight for the first time. And, I started small (or so I thought!)
The stuff's only been in the bucket about two hours and already it's tripled in size from the dry pellets! It hasn't even started bubbling yet! I don't even want to think about what a mess I'd have if I started out with a larger batch!
