started grow question 5y ago
If I have 2 months of veg left, what would be the drawbacks to mainlining to 256 colas if I’m already at 64?

Congestion of 256 colas.... our shitty unstable weather. Might be a Ontario botrytis accident waiting to happen. But with adequate spacing and separation through training and some luck weather wise. Could be a huge trim party waiting to happen.

Only drawback you have from creating so many tops is that she won't focus on building any huge colas, builds a even canopy instead.

64? looks like 32... I would leave it at 32 tbh. I think otherwise you're going to create some issuse with the roots and space and airflow. 🌱👍

If i wanted to lollipop this, how much should i take off? - lollipopping, scrog
When and how much should i take off? - Considering she is not very tall, but very dense. She has been defoliated quite heavily, both before and during flower stretch but i feel like she needs more. 6 week veg - 11 days since switching to 12/12 Sage n' sour fem in 12L coco 50/50

When to flip a mainline grow?
My grow is far from perfect, but ideally, when is a mainlined plant good to start flowering to get a large yeild? Just moved mine to finishing containers, pretty stalky, but not a lot of leaves due to method. Worried it would impede growth.

Mainline 3rd topping with only 7 nodes?
I'm using mainlining tech for one plant, the thing is one of the nodes didn't stretch yet, there's only one, I'm supposed to topping the 3rd node this week in order to have 8 main colas, but it looks like I have only 7, any ideas what it can be? I have no idea what it is.

Can I clone and mainline that bit I topped?
Hi guys, if I top my Amnesia, I mean, literally top them, Like straight cut at the 4th node, maybe? and leave the other 3/4 node above.. May I clone that topped bit? If so, since It should be growing like a normal plant as should be sprouting from the top, may I mainline that?

When should I do subsequent tops to form mainline?
After 1st topping on mainline formation, how long should I wait to do next topping? Doing outdoor hot AZ grow. Been topping 3rd node as 4th begins forming. Am I too conservative? With 2 weeks between topping, concerned about running out of time.

Should I cut or should I leave?
I finished my final topping for my Main-line grow and after a few days I noticed these growths starting at the crotch of every top. Should I remove them or does it not matter?

Is this normal growth for a mail-lined plant?
I mainlined 8 colas on both plants. Each one has a small stem growing at the beginning of each cola. Is that normal growth for a main-line? I thought at this stage it would be just 8 long colas. Should I remove them or just leave them?

Too many veggies (question re: length of veg time)?
I’ve had this Amherst Sour Diesel vegging for months. Is there such a thing as vegging for too long? Also, Miss Mia Wallace (as ive makes her) has had her share of issues from soils to nute issues and thrips. All seem to be under control. Will this impact yield?

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

Mainlining not so symmetrical?
I started my first indoor grow off with mainlining and 2 of my branches are growing nodes in a staggered formation, whereas the other 2 are growing symmetrical nodes. Does anyone know why this is happening? It’s grown from seed.

autoflower, extended veg time, due to mainlining "topping,training" and stable genetics and pot size ?
Could you in theory manipulate the veg time of an autoflower, by doing main-lining "lots of topping, training" with good genetics, oversized pot, 24 hour lights and good timing ? Ive experianced a few plants staying long in veg, without showing signs of stress or stunt.
