Hello
Misting can be nice for raising the rh in the space , but you want water at the bottom so the roots go searching for water and grow down in the pot.
Depending on the stage they'll drink more or less. Right now you may be able to get away with splitting 2 gallons between the 5 plants to not over water. As the plants get older have more leaves/height/ developed roots then you'll soak the whole pot with a little runoff and let it dry over a couple days then water again. A good wet/dry cycle will be what you're going for.
Happy growing. ✌️
