HansGoatanswered grow question 9 months ago High bro, when you are using HST for a cannabis plant you want to give her time to recover. Because autoflowers do not have this time it is possible but not recommended to use any type of HST on autoflowers. Just because you can not control the time that you want her to start flowering. But LST is ideal for autoflowers. You want to keep these 2 things in mind for LST on autoflowers. Try to keep all the buds growing on the same height and you want them all getting equal light from your lamp. And think about airflow, there should be some space in between leaves and buds. Enjoy your grow buddy!
