Plant position

Mainlining is when you top it at an early age and then the two main new growths you LST down and turn into two plants. vs LSTing the main stem off to the side like you have done. Can still work but weight will be distributed weird and could cause a snap. Support the stem if needed.

If you do that, anchor the base to opposite side before it pulls itself through the substrate (ripping roots / stress). continue to keep the top of the plant tied down for as long as you want. Keep tying down the top of the plant as it grows for as long as you want... Might need something to hold it up if grows out too far, of course. However, there is not much reason to do this outside. Unlike indoors, there is no intensity difference of sun from top to bottom.. even if that plant grows a mile tall. This is the ramifications of being 93 million miles from the light source. So, the only training you really have to do is to spread the plant out as best you can. Definitely worth potting up to a larger size outside as long as enough time remains (regional long nights start when?). Growth will be limited by the pot size unless it was a late addition outside. If you do pot up, keep it centered... that's about root formation not the above ground training.

even surfase = even buds if u prefer 1 big cola let it grow like she does it's really about light. if it's horizontal or verticale u chose ur metod

It makes no real difference, planting in the middle provides the biggest and strongest "anchoring" point, which can be more benficial when it comes to heavy training. Planting at the side has no real advantage, but can provide a slight benefit when tying the plant over if space is limited.

"It serves to learn and understand" "kind of mainlining" - If you don't try stuff you don't learn and understand. So whats the intention of the question 😆 Whatever someone says was a different environment, different plant, different camera, just an AI, just nonsense blablabla... Just do whatever you like pal 😂 Really hard to kill them...

, the mainlining starts with 2 nodes and will be topped down, i would only grow ur dtrain and then next strain
