I like training. Lot to think about with training
-is it worth the time or is it a better idea to plant a ton of plants and just focus on trimming
-one massive main cola could be pretty hard to prevent it from mold so splitting the tops can be necessary with some strains
-is it a matter of space, sometimes strains get too tall indoors and you need to widen them out to fill more space (because of plant legal limit)
-making a weed bonsai tree is beautiful
Its fun playing around with the plant and seeing what it can do, sometimes useful, sometimes not
Never remove more than 1/3 of the leaves at once.
