Ghost OG Bag Seed

First grow going well so far. Only issues have been: 1. Humidifier not reading very accurately, so have to set it to 50% to get 60% actual RH. 2. The room the tent is in gets very humid now, could see a fog one day, need a dehumidifier for that. 3. Water here is so hard that everything is being covered by minerals. Maybe I need a non-ultrasonic humidifier.
