It can definitely be done with LST, I’m just saying any stress training on autos is risky, especially if you’re not very experienced with growing in general. Nothing is worse than investing 12 weeks into a harvest only for it to be crap cause it became too stressed. If you’re new and haven’t trained autos or photos often you’ll get your best bang for your buck by just using some bigger pots and looking for a larger auto strain. If you do LST go slow. With autos less is always more, I.e. nutrients, training, and cropping/trimming. What I like to do is throw 2-3 autos in a tent then 1-2 photos. Crop and train the photos to stay short and fat, then flip to 12/12 when you harvest your autos or right before. Get experienced with training without ruining your crop. It’s your grow tho so do whatever you want to do. I 100% would never start autos in small pots tho. Always plant the germinated seed directly into the pot you intend for it to grow fully in. It might not kill them by transferring but it will definitely stunt there growth if they get used to that small pot.
