I'm using an outdoor greenhouse/grow tent and after returning from vacation it appears I have a mold problem. I have all of the flaps open in the tent but it has been an unusually wet summer so I'm assuming the additional humidity is the cause here. Besides cutting out the effected spots and opening up the door flap to allow for greater ventilation, is there anything else I can do to kill off/prevent this mold from forming? I only use a soaker hose at the base of the plants for watering so the top parts of the plant *should* be remaining dry.
