Hey there, bro! 👋
You can break and mess with the plant however you want, it will always show you its strength, superiority in quick adaptation, and resilience of its tissues compared to your body or your skin! I'm sure the genes of this plant are much older than human genes! But trying to split the stem will only slow down nutrient uptake and increase the number of stressful days for recovery! If such techniques are used, it should only be during the vegetative stage! Overall - you're awesome, dude! 👌😇👍 Good luck!
