Fun first week - Installing the Infinity inline fan, carbon filter and exhaust out the window was challenging, but rewarding. I have added a humidifier to the mix, and am now able to control the environment. I am using passive air flow ( 4x5 inch netted vent) from bottom of tent, for now. I may need to add a temp control fan at one point, temps not surpassing 75 degrees with lights on. I have learned a lot in the past two weeks, and look forward to your help along the way!
