Thanks Shed! I put the old pinchers to work and plucked away
She is a furry girl, hopefully she ends up just as frosty as the rest of the Sweet Seeds autos I've run!
Autos respond well to LST and you'll generally end up with increased yields over no training at all. Keep in mind that there is still stress in low stress training. Gradual adjustments to pull down the main stem, making the original top lower than other growth nodes and spreading out the canopy has been very beneficial in my experience. During this process, supporting the main stem is key as you don't want to disrupt or even destroy some of the root system below by pulling.
It's important to note that if you're running into water or nutrient problems early on in your auto grow, the plant may or may not react well to additional stress from LST techniques. I wouldn't say autos are hard to grow but sometimes they can be finicky, you want the most vigorous first few weeks of growth as possible to set the tone once they start transitioning to flower. For some people autos offer diminishing returns and less control compared to a dialed in photoperiod plant. I personally find them fun with an easy light schedule and the ability to start new seeds at any point while still being able to finish up other autos flowering in the same tent.
With that being said, you can still use higher stress techniques with autos like topping with good results. Hope that helps
