I am 3 weeks from auto seeds in the ground. What ...

High roller pretty much hit the nail on the head. Not knowing when she'll flip is the problem. We have little control over how and when autos will decide it's their "time". Most auto growers depend solely on LST to achieve their results and get higher yeilds. I use these same techniques with photo periods and it works very, very well. Ii IMO and only IMO, I would not top. Can't and won't tell you not to top, but I would suggest giving her a bend instead. Exposing lower growth to air and light will help it shoot up and become another main top. Reference: I used auto training methods on my current 'Blue Cookies" grow. No topping, just pure LST and the results are clear as day. I did this to show you didn't have to top photos either and still get the same, if not better, results. I take progression photos and you can check out the early weeks of that diary to see the bends I made and what I'm talking about👍. Wether you choose to top or now, LST is and would be a great addition to your grow space/techniques. Very little work for very high payoffs. Cheers man, good luck with whatever you decide! Please trust that LST is a favorable option, however, especially/specifically with autos. Hit me up in PM if there might be anything else. Happy grows, happy trails👍😉
