@leafy_greenz, yeah. It can be a bit of both. Depending on how you like to grow. Some ppl like myself like to lollipop. So stretching is not good. With autos if you have a big temp drop that exceeds 5c 8-10degrees you should think about running a 5-1 5 hrs lights on and 1 off. Or 4.5hrs on and 1.5 off. If you want to grow 18-6. Or when you time your lights to go off, make it so that they go into rest at the hottest part of the day in your grow room. Also to to keep a higher temp you can run your exhaust on a timer to turn off and on every 15 mins on and off or for 5 mins out of every 30. This will hold a high temp, once you have a fan in your tent running and always exhaust the high rh/hot air this will all stop the stretch. Take your pick. Happy growing buddy.
