well i thought it was good for air flow, i don't have much of an airflow issue cuz am in a green house but i have seen pruning work tho, i am no pro at cultivating mj in pots but i do liv of a farm,.we grow bananas and tomatoes most, and i have seen pruning work with our tomatoes , if you cut suckers off the plant redirects energy to the rest of the suckers meaning larger tomatoes, you can get large tomatoes by over watering them but they don't get as big and they have no flavor,(this is also determined by strain) when you get big ones by pruning suckers you also get less, but like mj we sell the tomatoes by wight so it all ends up the same and cuz of the neatness of the plant and limited branching we can put them closer to each other which makes for a large yield of large tomatoes. so am not sure if lollipoping is all bad or not cuz i know plants need foliage but i also know you can manipulate plants yields and growth for both good and bad by pruning foliage and suckers so am giving it the benefit of the doubt ( Am a cynic i have to try every thing to make up my mind)
