Same here...RH goes up and Temps fall to maybe 71deg at night...no problem so far...seems as though in the wild...nature does the same..
I would try to bring your RH down to about 40-50%. High humidity will prevent the plants from seeking out moisture in the soil since they are getting plenty through their leaf stomata. This could potentially lead to root rot due to over saturated soil! Sent from my iPhone using Grasscity Forum
That will certainly help maintain good temp & humidity levels. The plants will also appreciate some air exchange supplying them with some fresh CO2. Sent from my iPhone using Grasscity Forum
