Low Stress Training (LST) Guide

Quick update to the LST fun
That looks fantastic, what strain is that? I am thinking of moving my one girl from a 32 litre jug to a 5 gallon pail? Do you think that will interfere with her growth or cause problems? I am sending a couple photos as well for you guys to look at, I have done LST from when she was a young girlimage.jpgimage.jpg

I use electrical wire to train individual branches and to pull the top down to LST the plants. It works great to fill the space evenly yet still be able to move the plants. The plant on the right was topped once. The plant on the left was just pulled down to promote side branching and to lower it. Just put a hook on bottom of the wire to hook the lip of the pot and bend the branch as you need. The tape is there to hold it in place side to side to evenly spread the branches around the pot.
Brilliant idea, I will be scalping some of my extra chunks of left over ASAP

I start about two weeks or about 6 inches in and then I put her right on her side and keep her growing that way throughout. I'll do the same thing to the first 4 nodes as well but staking them down in opposite directions. By the time the real top reaches one side of the tent, the other nodes have turned into thick branches. I try to keep her in veg until she's staked out to the sides and at least 6 inches tall. I'm pretty heavy on defoliation too. All the time during veg and then once really good halfway through flower since its so tight I try to keep the air flow going.
What percentage or what do you generally look for when defoliating
 
When I defoliate, I take a schwazz approach and take everything that blocks any light off. If you could look at my grow from the side, there is absolutely no fan leaves left other than on the lower canopy. I left the lower canopy on because I have some pretty intense lights and I didnt want my medium to dry out. I'll defoliate about 5 times. Twice in veg, once at the beginning of flower and once three weeks in and then once right before harvest.

As for topping, I havent touched her once other than LST. She's actually laying directly on her side. I do this almost as soon as she gets growing. This makes every node get full light as soon as it develops and in turn, creates a solid top out of just about everything with a bud on it. Doing it this way cuts down on recuperating time from topping to zero.

Another good reason I do it this way is because I'm a lazy mofo (also the reason I do no till in a 60 gallon pot) and I like to do as little as possible. This method makes it so I never have to even see a net. It's not a perfectly even canopy, but everything gets light and a ton of it. I measure out my lights so the par is around 1100 at the top of my canopy. I'm using a total 10 cobs equalling 500 watts.

Looks great pal, did u just use LST or did you top it once?
Many thanks! This is my first grow, so I’m pretty happy and excited so far. I have some minor leaf tip yellowing going on which has me wondering what that problem is. Down to thinking light stress, N tox, or K deficiency but kinda leaning towards thinking it’s light stress as it’s only top leaves that seem to be affected (not all as with a tox)


And now I’m rambling. Haha

To answer your question I just did LST. They’re all autos and I didn’t want to shock them so I just did LST every day for the last week or so. Here’s a couple pics pre LST. I started my first LST session 2/27 and all this new growth is from the last 6 days. Now they’re sprinting into flower at day 29 of veg!

Like I said they look great, I have two auto grows in DWC hydroponics, I took a chance (even though everything I read said it was a huge gamble) and topped one of them, it recovered really quick luckily and I’m happy with it’s progress. I enjoy taking the time to tie them down daily and have them train properly

Dude, thank you! And that’s awesome to know that they responded well. I was just really hesitant as I have legit no first hand experience (just know what I’ve read), so it’s nice to hear that yours responded well.

I have actually just started light defoliation of fan leaves to improve light penetration this week, just a couple a day, and the plants don’t seem to be upset with me yet. Next grow I’m going to top one and see how it responds.

quick question for you- attached picture, what does that look like to you? I’m almost thinking some light stress (as I hadn’t adjusted my lights up in a week or better) but I suppose it could be nute burn or a deficiency of some kind. Doesn’t look like N tox to me because the leaves aren’t crazy dark, and it’s only appearing at the top of the plants. just curious for another opinion on this one.

Just my opinion and I am no expert by any means, but I wouldn’t worry about that? I have a few leaves on my plants like that. If it’s LED lights I read it should be 12-18 inches from the plant in flower?? But that’s just what the manual from the light said. And also with the topping thing, I’m sure it’s a gamble on every different strain and how healthy the plant is going into it. I just took a chance and it worked with the thought of not being worried about loosing the plant?? So update me if you give it a whirl,,, mine worked out ok with one topping? I wouldn’t dare do it a second time on her thoughimage.jpgimage.jpg

@BuddingHorticulturist, there are a lot of rumors regarding autos and the rumor that they cannot (or should not) be topped is one of them. As long as it's healthy, an auto can be topped between the second and third week. After 6 days of recovery time, LST can begin. Check out this thread on topping autos at the AFN. Good luck!
Sweet, thanks for the link, I will be checking that out for sure, I always read it was a death wish. So going in I expected that but wasn’t to concerned since it had to be switched to 12/12 because one of my plants wasn’t auto grow.

No problem. The examples in that thread will clearly show that it's no death wish. Just remember that the auto needs to be healthy otherwise it is kind of a death wish.

It's not a death wish. The logic behind it is that an auto has a finite living arrangement regardless of light schedule. It's going to finish. So a lot of people take the approach that if you cause any harm, it takes out time from actively growing to heal which in turn takes out time from its finite arrangement. I myself don't bother with topping because you can create the same effect different ways. LST in general is specifically made to produce more tops through its methods. I would rather have my LST'd girl forming strong colas on the entirety of her than to risk causing even a day of non growth to heal just the main cola. So I adjust my time in creating an environment that best helps growth.

There is some science to the madness. Especially in strains that grow in less than 60 days. That being said, it's a weed so experiment. The worst that could happen is you hurt your yield. You could make it better too!

awesome! Thanks man, yeah I felt it was minor but being my first grow was a little worried. It doesn’t seem to have progressed any more today so we’ll see.

and the topping definitely seems to have worked for you!!!
