My advice: sit back and let them do their thing.
Hops have been around a long time and grow in the wild just fine without any human intervention. If given space, water, and ample light, they grow like weeds.
We got a few inches of rain over a couple days a week or 2 ago, thunderstorm after thunderstorm. In my heavy clay soil, the hops were fine.
I wouldn't worry about them being in pots the first year since the main goal here is not harvest, but getting the plant established. I would plan on planting in the ground next year. Remember their roots spread so much that they need to be pruned every few years. Give them room and some sunlight and have a homebrew.
