Secondary or not on a London Porter Clone?

I’m fermenting a London Porter Clone OG 1.054 using WLP002 English yeast

What timeline it’s the recommended, and secondary or not?

Throw away the idea of "timeline" when fermenting. A porter with with that OG is not going to be done when you want it to be. Depending on temperature, starter, etc. it could be done with primary in a few days, or it could take weeks. Make the starter, pitch it, seal it up, and forget about it. I wouldn't even bother with a secondary, just leave it in the primary until the FG is constant over a few days, then keg or bottle. You could even leave it sit for a month if you wanted. Sounds delicious!

thanks for your help, i will take readings of the gravity and let it sit on primary until done.
