ya i also work at a nute manufacurer and some other researchers. and anything more than a 10 degree swing from day to night may cause mildew..not will...may, or could. that is one of the mahy ways to get it.
and again weve tested these theories and put science to it and you dont want them low tmeps or much of a swing at all or they dont process the foods the way we make them to. and again, im not saying they stop but it does slow the whole life process. and that makes for weeker budz. not shit but weeker. that all depends again on how often the room isnt dialed in or the strain. weed indoor is always more potent than outdoor. we have absolutly no control over environment outside so its impossible to be better than indoor with stable conditions.
