I've had a bagseed seed female in a growbox for almost a month and a half now. My problem is I only have like 3 feet to grow in. I know multiple factors affect height like the size of the pot, how far away the lights are and what height you flower at. I'm curious as to how to keep my plant from outgrowing the box, allowing me to flower for as long as possible. I began flowering at around 6 inches 2 weeks ago. I'm wondering what will prevent my plant from growing into my lights, burning her. In essence what is the golden rule for height, an accurate way to predict it?
