training saplings

right now i have a lil sapling (my practice plant) and unfortunately my current situation doesnt allow me freedom to give it the evironment it needs (a growroom) so its stretching like crazy but no big since its the practice plant..but how soon can i start training..i was thinking of LSTing it just to see what happens but ive already murdered 2 plants with MG and im not looking to make it 3..any help would be supa groovy

Without the "proper enviroment", your waisting your time and will without a doubt murder another one. If you can't create grow space indoors, put it outside.
