Wanted to introduce myself here. I've been reading the site for a week now, along with nearly every home brew site around! There's certainly no shortage of information out there! I found interest in home brewing after visiting the Sam Adams brewery on a recent trip to Boston, and after watching a beer documentary on Netflix. Then, I remembered that when I was a kid, the father of one of my friends made his own beer. Well, after poking around for info on the web and visiting the local Noble Grape, here I am! I needed a hobby outside of my motorcycle (especially this time of year), and this seemed like a great combination of creativity, technology and well, of course, beer.
I'm starting on a Festa Blonde Lager for my first batch. My plan is to do maybe one more Festa after this and then move up the difficulty scale once I have a little experience. I'm in an apartment and will have to sort through the challenges brought on by that, but I'm very excited!
On to the help part. I followed the NG instructions and am doing my primary in the bucket with the lid loose. Here are two pictures of the fermentation:
At 18 hours:

At 53 hours:

My question is, do these look right? Also, based on the instructions, I feel like it's very close to ready to rack. I plan to do that just under the 72 hour mark. Would anyone advise against that?
Also, I have the primary bucket set up about 12 inches off the ground... I'm going to need to raise it to help with racking. How careful do I need to be about lifting the bucket and disturbing sediment?
Thanks in advance!
