That's why I take part of the covering off after I spray. Covering is mainly for heat to keep it around 82 ambient. If I take the covering off the temp drops. If I don't use eco earth I don't have the humidity. There seems to be a big range in what people use for their humidities. My understanding is as long as there is airflow 60%-85% is just fine. I've seen quite a few different thread here and other places with a big range of humidities that work for people.![]()
