Hey @ edsmokesalot!
You have a few options witch can be used alone or may be combined:
1. Take some water bottles with the mouth cutted down and full of water. Place them around the pots and let them be still. If you use almost boiling water this will increase the evaporation of them.
2. Water one or more towels and place them on the floor of your growing tent.
3. Do the same but place them in hangers and you can sprray them with water 5/6 times per day.
4. If you have a bag of perlite, place it on a pot and keep watering it (as sauna rocks work for a sauna).
5. Just sptray water over the walls of your grow tent and/or over the floor. This is the less effective.
Good luck! I'm in love with Big Bud from Sensi. Their growth is fast, they are resistant to almost any problem. Requires little attention compared with some other varieties.
