after seeing the quadline method, i have to agree, the mainlining/manifolding takes a long time and is perhaps not the best method to use, it is easy it seems to train the plant how you want.
havent updated mine in a couple weeks, busy busy, but now in flower, had a slight blip whereby the caretaker missed a feed whilei was away last week and the gas1 took a hit, had to cut a whole arm off lol
this technique has helped me keep the height low for sure, tho i think i should have swapped the light schedule at different times for each one, wasnt possible this time as it was my first grow and wasnt ready really, no idea how the yields will turn out yet, but i definately see the time extension as the ultimate drawback here.
mine had like 10weeks in veg in the end,
i will try the quadline next time as it seems much faster but still a great way to combat height restrictions for those of us who have them, that or try to stick to short strains lol
