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. 🌱👍

Mainlining or Topping?
Hey everyone, my Frisian Dew plants are in week 3, and I’m unsure if it’s too early, too late, or just the right time for mainlining. I have no experience with this technique yet. Should I just top them instead? Any advice is appreciated! 🙏Week 3

Do you think the girls are ready for the flip to 12/12? I am mainlining so both plants have 8 grow tips (topped 3 times). It has been a week since Long Shanks got her final topping and 3 days since Sweet Baby James got hers. (I have circled the 8 grow tips in the photos).Week 6

Mainlining defoliationI switched to flowering 2 days ago. On the defoliation side of the training, when there are grow tips that are growing from an under node, do i keep them or do i remove them? I don't want any larfy buds and i want the plant to focus into the 8 mainlined colas5y ago

Training?How exactly should I go about this plant when it comes to training? I've not grown a fem in a while and I'm just looking for a full canopy (or as full as possible). I know about topping, fimming and tieing down the branches, but is there some other/better techniques?4y ago

Mainlining worth it!I used to think mainlining wasn’t worth it because of the longer veg time but, that seems to be the only downside. Theres way more advantages with this technique I’ve found, especially after my latest grow.
What do you guys think about mainlining?Techniques. Main-lining

Tieing down colasShould 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?Week 4

Main-Lining: cleanup center of plant and wait or stop cutting and switch to 12:12?I am not sure if I should remove the top 4 small branches that are growing up on the second picture...
As you can see, I used those green rubber-coated wires to bind down the main branches.
But on both sides of the stem - 2 small branches are shooting upwards: keep or cut?Week 5

Number of colasTo other growers which top and manifold their plants, do you prefer fewer branches with big colas for example 6 or 8 main colas with everything else trimmed off, or do you prefer as many branches as possible as long as they reach the top canopy?Week 6

Mainline with Nebulas method for 10 topsHas anyone kept the second top node so you end up with 10 tops? ( Cutting off the bottom on the second node)
How did it work out?
Are there any drawbacks except space?
Would it be an uneven split of nutrients decreasing the yield on the 8 main tops?Other. General questions

Broke Stem branch while main-liningNow it's standing straight up to heal
It's still growing and look healthy, but what recovery time should I expect?
Will it be strong enough to continue main-lining?
Should I just release the other branch?
Or wait until it's healed and continue?
Thanks for your tips and inputs!5y ago
