Twisted some have said that if you top an auto it will give you time to train it ,I have heating mats with thermostats in every area that I do autos ,I upgraded my light old ones were 6 300w leds .I couldn't get more than 2 ounces from one plant, new light is an 800w cob , I guess my point is that light affects yield,grow medium affect yield , stress affects yield pretty much anything that slows them down affects yield
