Do I Let these branches grow?
THC123
started grow question 6y ago
I am mainlining this plant, but I’m not sure if I let the branches grow off at the every node or snip them off so the focus goes to the main cola?

You want those yo.. don't snip them off.. you can leave like 2-3 sites below the main one and be ok! Happy growing! 👊

mainlining should be split at a node of symetrical growth (if not a clone) and then again as many times as you want until foundation is set. This one looks cool, found searching "marijuana mainlining" on duckduckgo images: https://imgur.com/qnpPYDu

Mainline/Manifold: Trimming fan leaves after done with topping.
Finishing up the topping portion of mainlining. P2 to be Nebula-Haze style and P3 to be Nugbuckets style. I'll be trimming growth tips other than from the 8 cola sites on each. Still keep un-shaded fan leaves below those levels? A lot online shows all lower fan leaves trimmed

Flower Stretch and Mainlining
Flower Stretch Question When I flip to flower, she will stretch and about double in size. Does this include all the bare growth I have cleared off during toppings? ie, if the stalk at the bottom is 12" from the bottom to the start of the last topping, does that 12" count in?

Tieing down colas
Should I tie down the main colas on these girls to get a more even spread to or just keep letting them do their thing since they are growing into monsters and looking pretty even. Is it to late to tie down the main cola as well will this stress thre out during her stretch phase?

How many colas can I fit in a 2ftx2ft before crowding becomes an issue?
I will be mainlining my plants to 8-16 mains and I'm trying to decide how many plants I can fit in. I was thinking between 2-4 plants, which would be 16-64 colas in that 2ft x 2ft area.

Mainline inconsistency
I started mainlining my plant and one of the main branches stopped growing completely :s Anyone seen this before? I’ll probably have to top her a few more times to make up for it.

Yellowing leaves after first Mainline top. Light stress?
Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!! I have raised light to 23". Am I on the right track here?

secondary branches stretch during flowering
I've been growing Moby Dick using a mainlining technique. During the stretch phase, some secondary branches have grown a lot and are not close to the main stem anymore. Should I keep them? Should I cut? Will they help making big, fat colas?

More training now? or leave her longer?
I've attached image from 7 days after defoliation and more LST and what she grew to today. Quite bushy, should I defoliate/tuck again so more light gets to lower branches? only do some more lst? more lst and defoliation? or leave her for now and let her grow? 35 days from seed
