B_dawganswered grow question a year ago I use a tent with auto ventilation to control climate. humidity 55% 60% and temp I like 60-66. I have a basement and can keep it cool without a/c unit and just maintain that humidity. I also try to plan harvesting around cold months. If you can't keep it cool it will greatly affect your outcome. Same with humidity but I find it easier to control with the equipment I have.
