MrStinkyanswered grow question 3 years ago If you cant get a new humidifier in the tent, what kind of air intake do you use? Active or passive?
If active you can put your intake hose over a bucket of water to pull air and more moisture in to the tent.
If passive, is there anyway for you to increase the humidity outside the tent?
Final thought is temperature - if you can figure out how to reduce temps (thinking back on your 94oF tent temp) your rH will increase naturally.
But like Papa_T said below - you really want a 1 gal / 5L humidifier, one with an auto setting even better
