Highly agreed!

Once I started leaving my beers in primary for a minimum of 21 days they have improved greatly! Yeast need time to clean up their fermentation bi-products!

Yes,definitly. I let the beer get down to FG,then let it sit another 3-7 days to clean up & settle out clear or slightly misty. Then bottle. They'll nedd time to not only carbonate,but condition as well. I've found conditioning takes about a week longer than carbonating on average. It does depend on the gravity/ABV as well.

+1 for bob's comments. There's a very strong case to be made for leaving it on the primary for longer than what is strictly needed to bring it down to FG (if Revvy were here, he'd give you many more reasons why). But if it's already been on for three weeks, I'd say extra time in the bottle is probably more beneficial than extra time on the primary, on balance. But leaving the beer on the primary for 4 weeks as opposed to 3 will almost always give you better, clearer, cleaner-tasting beer, as opposed to imparting "trub flavors", whatever that means. And autolysis generally takes WAY longer to become an issue than the time periods you're dealing with here. Don't fear the primary!

Get either a hydrometer or refractometer ASAP. Having a way to get gravity readings is important. I'd say its even more important (critical) for new brewers. Until you've brewed enough with the same yeast, under a range of conditions, you need a way to KNOW when its actually done. Then you can let taste tell you when its time to move the batch to next steps (bottle, etc.).

Check the gravity. If it's terminal, then bottle at the 4 weeks. 1 extra week or so should be good enough for any yeast clean up.

I'd rather have a better chance at proper carbonation than worry about 4 vs 5 weeks primary.

I'm not arguing, by any means, but hadn't read anywhere about the yeast cleanup. It makes perfect sense, but i've read a couple brewing books & guides and hadn't come across it.

I also agree with your conditioning process. room temps for 2-3 weeks at a start. I usually only put beers in the fridge when i know i'm going to drink them in the next week or so.

A question. would leaving in the primary to let the yeast "clean up" be better than racking to secondary, or are the generally the same process?

Leaving the yeast in primary is more beneficial to clean up since its the yeast that does the cleaning up. If you rack to secondary you leave the yeast behind

Thanks. I would think that the yeast left in suspension would still get the job done in secondary, but i'll try leaving my next one in primary longer to see if there is a considerable difference.

It's not better or worse. Either way, there should still be plenty of live yeast in your beer to ensure proper clean up.

That said, if I were racking to secondary, I wouldn't do it until around week 3 (or when it was time to dryhop). Reason being, I would want as much clarity as possible. Let gravity, patience, and time do 90% of the work for you in that regard.
