First Grow Ever

Week 2 has started: Day's 1/2 nothing out of the normal watering with spray bottle and 20/4 hour schedule. The seedlings are about 9 days out from germination/soil. They have solid first leaves grown, and are starting to show growth for the next set. Growth seems slower, maybe be due to humidity being at around 60-70%. New humidity controller coming in to help me control for 50-60% Day 10: new leaves are showing, still spraying with spray bottle when dry. Humidity hasn't been controlled. around 65% atm which is better than 70%+ Humidifier comes on Saturday which will help keep in the 50-60 range. Plants seem to be doing well? Not sure, at least not dying lol
