How many members does r/fermentation have?
r/fermentation has 321,014 members as of our most recent crawl on Aug 11. Prowlo re-checks tracked communities on a rolling schedule, so this figure moves rather than sitting frozen at whatever it was when a scraper last ran.
Is r/fermentation growing?
We don't have 30 days of snapshot history for r/fermentation yet, so we're not going to invent a growth number. We've been tracking it since Jul 30; the chart fills in as history accumulates.
How active is r/fermentation?
We don't have a reliable posting-rate sample for r/fermentation yet. Subscriber count alone is a poor guide to whether a community is active, so treat this one as unverified until the crawl accumulates more.
Can I promote my product in r/fermentation?
We don't have a promo-tolerance read for r/fermentation yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
