Day 17 I gotta admit my humidity levels had dipped to the low 50s last week in the tent. I tend to think that was all due to my house central air conditioning kicking in. Hot and muggy outside, and the basement where the tent is was super cool (nice retreating area from the heat) So it sucked my humidity down, but different story now. The number listed has been steady past 4 days, no ac on helps. So with all 5hat said and done, just a light watering with MC added in today
