russrahlanswered grow question 4 years ago I have done both, if your doing a photo period strain then hands down topping and LST wins. But I have also done autos and photo periods without topping and training them under a short screen and I’ve also grown them out naturally then pushed them down and out to fill a screen as well, lots of options. Lol They all work, but if your not doing autos then a well timed topping or 2 and LST then use a Scrog screen is the way to go. Autos are hit and miss when topping and only should be done when you know the strain can take it and you are experienced enough to pull it off. Hope this helps, Cheers! 💨
