Between roughly day twenty and day thirty five an auto can double in height, and this is the window that catches out anyone with a low tent. Nothing you do after that changes the frame much, so light distance and any training need to be settled before the stretch starts. A day by day height chart for a few common strains is plotted on https://turboautoflowerseeds.com and it shows how sudden the jump is. I hang my light at maximum height going into week three and lower it afterwards.
