so, yesterday i brewed my fifrst batch. last night there wasn't any signs of fermentation. this morning when i got up, the lid had blown off the ferment bucket and the air lock was blown out. i cleaned things up, and placed the lid back on. this afternoon after i got home from work, i checked on it again, and there was krausen in the air lock. i took it out and cleaned it in sanitizer, and place it back in the bucket. i just went and checked on it again, and there seems to be air bubbles at the rate of 1 every 7 to 7 seconds. does this seem like everything will be ok, given the mishaps i have had so far? and does anyone know why the lid may have busted off overnight? thanks for all the information.
