Just google does mainlining increase yield There’s too much evidence suggesting it does then it doesn’t the only people that have suggested it doesn’t work are people from this form
When you say it works ,,,to what extent ?
deffinately isn’t going to give you double the yield as you earlier said it would .
all training when done right should give an increase of yield Compared to an untrained plant ,,,but your hopes are set way too high.
a plant will only give as much as its Genetics allow ,,,so be interesting what strain you choose to grow .
if You get a pretty plant looking like you’ve seen on YouTube it will be at the expense of extra veg time ..
so Over a period of time I you will get less harvests coz you veg too long ,,much better with more and quicker harvests from plants that have had a simpler form of training with lots less veg time ..
thats The reason why your getting opposing advice to what you want to do ,,
But it’s your plant = your choices,,,Sounds like your gonna love growing anyway ,,,,so enjoy.
