I have two batches in primary fermenters - one bucket and a 6 1/2 gallon glass primary.
It seems the bucket - although sealed - does not exhibit a strong fermentation in that the airlock does not bubble much or at all. I peaked in through the airlock hole and after nearly two weeks I see a decent amount of foam (krausen) on the top. I suspect I should leave things alone however I have been told NOT to leave the wort in the primary longer than 2-weeks.
The glass primary is working fine and will be on schedule.
I suspect bucket fermenters do not have a 100% seal is the issue and I am OK is my theory.
