You are fine. The only thing you will need to do since your humidity is so low is to make sure that you are giving enough water. Not enough so the soil is soggy all the time, but enough to keep the plants turgid. Your humidity will probably increase a little as the plants grow larger and have more surface area to transpire moisture into the air.
In bloom, those numbers are very good.
