Hi Andre, Can I ask a couple questions?
Did you buy a standard or dwarf Meyer Lemon? How big is that pot? Is it grafted or seed grown?
Now, your questions: Damp, always damp. Not wet, not dry, just damp.
I doubt 5 hours a day of "pretty direct sunlight" will be enough to make it bloom but that's also an age thing. If it has enough sunlight but its seed grown, it could be years away from blooming (up to 20 years). If its grafted, maybe only a year or so. The amount of sun will be the determining factor: the more sun the faster to fruit.
If its a standard Meyer Lemon (or seed grown) you will spend a lot of time pruning and shaping. If its grafted, any branch that looks suspiciously different or especially vigorous is from the roots and should be removed.
