My PH has been 5.8 through out the whole grow except for one week in the middle because my pen broke and had to wait for a new one. I watered every two days.I don't know what is RH? I have a TDS meter but don't know how to use it. lol
It has been very, very humid the last 4 or 5 days in my bedroom, where my tent is. Should I get a dehumidifier for the tent? If yes which one is small enough?
