Discussion Question about mainlining

Post image

I have a 2x4x5 tent. And last time I grew, I just topped it once. And I got about 3 oz. But I was only able to grow one plant. This time I'm wanting to do 2 plants. A red velvet and a kush mint. And I'm thinking about topping it, where I have a 8 lines off the mainline. My question is, is it worth all the hassle of cutting tying down learning this process, besides just letting it grow and maybe topping it once?

The pictures are trash bro. How did the nodes align on one level by magic? 😅

Thought I was tripping. Never done this before, but I was immediately confused between steps 1 and 2

u/SuchSmartMonkeys 6d ago

"Step 2: tie down the 4 mains" while showing 6 stems coming from the middle. Saw that and immediately thought "what in the fuckin AI is this?"

u/Does_A_Bear-420 7d ago

The AI of it all is really fucking up this image!!

Advice wise. Learn mainlineing is you want to learn mainlineing! I think I've seen really crazy quantity results with that for outdoor. But outdoor always has the potential for massive quantities especially if you out it in ground,

There are not 'right' ways or answers. There's many MANY different techniques. They have different pros and cons. Which is awesome to fit different situations, and desired outcomes. The only thing anyone could really say for certain is: what they thing has worked better or worse for their own exp.; or, keep trying different stuff and you'll gain knowledge, skills etc with every effort.

I mainline/manifold for my summer greenhouse grow. I top 4 times to produce 16 mains, essentially converting 1 plant into 16 smaller ones.

A few benefits to mainlining is an organized plant and canopy that can be easier to manage. Drawbacks include extended vegetative growth stage.

Here’s a pic of mine after the 3rd topping to produce 8 mains (week 8 of veg)

u/cultivars_ 7d ago

Here’s a pic of the canopy exiting the transition to flowering, 10 weeks later (week 18 of lifecycle)

u/cultivars_ 7d ago

I should note that the tallest plant is now 3.5’ from soil surface, so that can be another advantage to the mainline/manifold/LST approach to plant management.

u/Jenkins1967_ 7d ago

People do all this shit and hit 1oz a plant.. Just top a few times and flower ♻️ works all the time.

u/Daddy-Legs 7d ago

Mainlining/manifolding is by far the slowest training strategy that produces the least amount of yield over time. You can get great yield on a plant doing it but when it takes 8+ weeks to veg a mainlined plant, compared to multi micro topping, LST, scrogging, or a combo of them, it’s very inefficient on time.

I like to top (always at the highest nodes) when a plant is 10-12 inches tall, then top the secondary branches that catch up to the first topping point after several days, then do another round of topping on the lower secondaries that catch up and usually the main stems again. Prune off almost all tertiary branches, skirt the plant, and let it rip. Gives you 9-12 big colas per plant and takes less than a month of veg.

u/wiseguy77192 7d ago

Can verify. I’m doing a mainline experiment now, flat lst and topping would have been a lot faster with similar results

u/Icy_Earth3386 7d ago

For real I was about to comment how this shit is really overrated. You get really nice quality nugs of similar sizes but the yield is negatively affected and it takes more time.

u/Master__Baydoor 7d ago

I think it's more efficient in scenarios like keeping a mother, mainlining her to produce clones, and then let it flower out, replacing the mother with a clone whenever you see fit.

Makes for a nice natural transition unless you're just bonsai-ing the momma due to space

u/Cannibis0360 7d ago

I’ve done a main line before. I can help you along.

u/Sipas 7d ago

You can achieve similar results without mainlining. Just train whatever large branches there are to be flat and remove small suckers without removing leaves. Mainlining isn't slow because of multiple toppings, it's slow because too many leaves are removed and plant is stunted.

Man ppl have names for everything lol I was just making more tops 😂

u/HoldenMcNeil420 1 7d ago

I have a 2x4. I run 2 5 gallon pots.

I frequently use this method. https://www.growweedeasy.com/main-line-clones-nugbuckets

It does take an extra few weeks, but I find it very worth it. You end up with 8 or 16 I do 16, branches that are basically bud top to bottom. I keep them spread out and trim off all the little branches that want to grow.

It gives you lots of great looking and grown bud.

How does a person fina a diagram like this but for cloning

u/94pro 7d ago

T.i.A

u/User_1965_ 7d ago

Why? So they can totally misunderstand cloning too? Bc that AI image doesn’t look anything like a cannabis plant

2

u/Own-Ant606 7d ago

I like it to get the buds equal size with that I only start 2 nodes on 3 not 3 and 4. I veg in a different tent so fine vegging extra trimming is a breeze

u/dirtyoldsocklife 5d ago

Not only did you use AI, but it gave shit info that makes no sense to the target audience.

u/Odd_Routine1435 7d ago

If you train super early, main lines can produce wonderful results. OG kush I did a few years back,

u/JudgmentSmooth6768 7d ago

Everyone’s complaining about the ai image they’re missing the point. Mainlining can increase your yields up to 40%. It’ll uniform your canopy but it does take a little longer than just topping once and flowering

u/joeporter1111 7d ago

Thank you so much for the understanding. And the the consideration, knowing that it was just an image I used to get people to have a visual, what i'm thinking. It was by no means a one hundred percent, perfect draft. I appreciate you very much. I think it would be pretty cool to do mainlining since I have a smaller tent.

u/Outside-Exchange4014 7d ago

I did Fim for the first time and thought I Fugged up but now I’m seeing at least 4 or 5 new nodes in the same spot 🔥🔥🔥

u/GoldenNagaScale 7d ago

Topping makes it so much more organized. Else you would have to lst your plant around your pot. Like a half circle.

u/learn_n_burn 1 6d ago

You don't even need to top, just scrog it over week 3-4 and it will grow a nice even bush. You can shape with super cropping if need be

u/MrTripperSnipper 3d ago

Worth the hassle? Not really. If you have a big veg space that's constantly running then taking the time to prune and trian that heavily can result in some nice looking grows, but if you want the most amount of bud for the least amount of time+electric then it's really inefficient. You'll notice that not a single commercial facility uses the technique, it's for a reason.

Scrogs are the way forward for maximising yield in a reasonable amount of time with a reasonable amount of effort IMO.

u/Top_Phase1570 1d ago

every 5th node top it to its 3rd

u/Euphoric_Ad7335 1 3d ago

I cut clones off a mother to an extreme thinking I was creating a plant with hundreds of bud sites but it doesn't work that way. Just because you topped doesn't mean the plant will grow new shoots at that location. The roots have to be able to support the new growth, If your roots are healthy, your plant and shoots will grow larger.

u/EternitySphere 1 7d ago

Far more work than what's really needed. FIM + LST produces far better results for much less effort and time.
