Just an update...6 days after pitching and I cannot believe the krausen on this! When will the madness end?
Some yeast strains form a krausen that is dense and sits on the top like a raft, not falling like others. That is why you check gravity and not krausen. You just rack the beer off from under the krausen.

Either way, be sure to let the beer sit for a minimum of 2 wks to finish fermenting and conditioning (cleaning up after itself). 

I think I may have this ^ situation. Checked gravity again today, moved slightly from a few days ago but certainly close to FG. Moved from 1.057 to 1.012 in a week. Still have the same exact huge float of krausen on top, airlock activity is very minor.

justin- what yeast did you use...might have missed if you said somewhere.

does anyone see a difference in krausen between liquid and dry yeast?  i typically use liquid, just used dry on my last batch, and was worried when i didn't need a blowoff tube (s05 in place of my typical cali ale yeast).  still hit FG, so i'm pumped, but wondering if this is typical.

The biggest difference I have noted is from fermentation temp.  Warmer temp = bigger krausen.  Lower temp = smaller krausen.  Same yeasts, same recipes.

i don't think dry vs liquid = krausen formation difference. with all things equal (like dry vs liquid strain) i think the amount of cells pitched, properly oxygenated wort, fermentation temp,  will produce different results in krausen and perhaps blow off. ive used dry and liquid yeast in like brews. with liquid hefe strain, ive had very active fermentation at 65F max temp, but no blow off. when i reached 68-70F temps, more krausen and blow off tube needed. also need to consider head space...less and you're more likely to need the blow off tube.

ok i think that's very similar to US-05, and Ive had krausen hand around much longer with that strain.

It's usually a lot more dependent on yeast strain than liquid or dry.

A photo below. Still floating there like a piece of flotsam in the ocean. Based on the recent gravity reading and the the fact that the airlock activity is little to none I'm thinking it's ok to throw in the dry hops.

What is the consensus of the group?

Are you going to stir them in?  It may be a better idea to put the hops in a secondary and rack the beer from under that stuff.

I am not planning on secondary. If it's still there come this weekend I'll rack from below it (seen other posts around about this same issue).

Regarding the hops, I was just going to drop them in. I can make a small break in the krausen by stiring gently on top w. my Thermapen. I suppose I could dump them in the middle of the krausen.

If you lower the temp by 10° or so it might just drop out.

I'm not too worried...it'll either drop during cold crashing or I'll siphon from below it. I'm questioning dry hopping at this point.

If you at racking......rack, then dry hop.
