It's hard to say for different growers, but you should expect it to take at least a year and a few months to flower from seed if fed regularly. But this can vary a lot depending on conditions. I usually keep seedlings quite wet (raising the water level up for the first month or so) to make sure they don't dry out. Granted, I'm usually not around so I can't monitor them). But once you see germination, and they start establishing themselves, you can back off on the water.
You're likely going to get a lot of varying answers on this part, but a lot of it depends on how tall the pot is, the media you're using, the compactness of the media, etc. Other influencing variables can be whether or not you're using saran over the seedlings or not, which is also debatable, but is something I always do since as I said, I can't monitor my seedlings for up to 2 months at a time.
If using a tall pot, water levels will have to be even more elevated. But if media is very compacted, then you won't need as much water to keep the media surface moist...for example.
good luck with them!
