Skrapi Posted September 26, 2012 Share Posted September 26, 2012 I have heard about LST and that it is a grow technique, but i don't know how it is done and why. I would really like to hear from anybody willing to shed some light on the LST grow style. Link to comment Share on other sites More sharing options...
mopman Posted September 27, 2012 Share Posted September 27, 2012 LST, short for low stress training, is a technique used to keep plants at a low height and to fill out the canopy. It can be used indoors or out.Auxin is a growth hormone produced by the growing tip that inhibits the growth of side branches. A common way of stopping its production is to cut off the top of the growing tip, Then the side branches, now uninhibited, grow in a rosette around the cut tip.LST inhibits auxin production by bending the main branch, including the growing tip, so it is in a sideways position. As it continues to grow it is trained to continue horizontal growth. The side branches exhibit gravitropism; they orient themselves based on gravity. Since the stem is horizontal the branches start growing vertically. Each branch becomes a vertical stem.Keeping the main stem horizontal saves a lot of vertical space so it is convenient to use when it is at a premium. This is not its only advantage. It is an excellent way to grow large plants. Each of the side branches off the main stem becomes the equivalent of a vertical main stem. The single plant can spread out and become much larger than it would have if the main stem had been growing vertically.There are many ways to keep the stem horizontal. Stakes, screens, and ties are often used. Indoors, the stem is often bent in a spiral within the container to conserve space within the canopy. However, in some circumstances it may be more convenient to keep the stem horizontal and straight. The advantage of that is that the new vertical stems line up in a straight row. Other advantages are that the plant does not grow as tall as it would have untrained, and does not have the stereotypical symmetrical canopy found in both top pruned and unpruned plants.Outdoors, to grow the largest plant possible, start it early, perhaps under lights indoors. Use supplemental lighting to prevent flowering. Set the light cycle so it breaks up the dark period for a few minutes several times each evening. Give the plant LST so it has a lot of vertical "stems", each ready to produce side branches. Then let it grow out.A similar technique is grow a plant in a container without pruning its top until it reaches a certain height, then turning it sideways so the main stem is horizontal. The container has to be modified so the roots can be watered from the new top and drained from the new bottom. The new side, which was the open top, must be sealed. The branches that were growing sideways will reorient themselves vertically and grow their own side branches.http://www.cannabis....ary/5879-ask-ed 2 Link to comment Share on other sites More sharing options...
Skrapi Posted September 27, 2012 Author Share Posted September 27, 2012 Ok cool thanks for the info mopman. That really helped and it looks pretty interesting but i think i'll shelve the technique until i have a few grows behind me. 1 Link to comment Share on other sites More sharing options...
Dust Posted September 27, 2012 Share Posted September 27, 2012 Think Mopman said it all very nicely You'll find a few LST grows on the forum in the grow journal if you have a little time to check them Have a good grow man and good luck if you try LST Link to comment Share on other sites More sharing options...
youungtoker Posted October 10, 2012 Share Posted October 10, 2012 im doing some autos as a side project would this method be ok for them or stress them 2 much ?. thanks guy Link to comment Share on other sites More sharing options...
Dust Posted October 10, 2012 Share Posted October 10, 2012 well some people do it on autos too, personally, i don't like too touch to autos too much, it will work and porbably do them nothing wrong, but will probably slow them too for some daysTry it on 1 and see how the result goes compare to others and keep us updated Link to comment Share on other sites More sharing options...
youungtoker Posted October 10, 2012 Share Posted October 10, 2012 yea no problem man i will try and get some pics up when they further on as they only at day 10 but they seem pretty healthy. thanks 1 Link to comment Share on other sites More sharing options...
underground Posted October 10, 2012 Share Posted October 10, 2012 lst is perfect for autos and any other strains - it is must-do in your garden - using LST i harvested about 75g from autoblueberry f1 from DP outdoors which is, for me and our cold climate, amazing resultbut remember that autos dont forgive mistakes in veg cycle Link to comment Share on other sites More sharing options...
youungtoker Posted October 11, 2012 Share Posted October 11, 2012 yea im worried about annoying them to much would lst or scrog be better for autos ?. thanks Link to comment Share on other sites More sharing options...
Elektroski Justovski Posted October 11, 2012 Share Posted October 11, 2012 Get her on the knees man, thats lst for me. lol 2 Link to comment Share on other sites More sharing options...
youungtoker Posted October 11, 2012 Share Posted October 11, 2012 going to give it ago when the best time to start it would you say ?. Link to comment Share on other sites More sharing options...
AlePol Posted October 16, 2012 Share Posted October 16, 2012 esta bueno el LST, aprovecha mas la luz la planta y tenes asi mismo mejores resultados. a mi me funciono de 10 Link to comment Share on other sites More sharing options...
Guscode Posted November 11, 2012 Share Posted November 11, 2012 Right now i've got an "alaskan ice" under LST. I use LST only in my little old 'n mainly unused HomeBox. It is perfekt to save space. I've got also the feeling, that the LST increase the amount of herb per plant when you harvest. But i didn't proof it under scientific circumstances. Wish you a good result when you dicide to try a LST grow. Feel free to contact me personally when you've got a question about LST. I've got a technic, that allows to morph the Plant in every phase of the grow. So you can adjust the height of every branch. I think that that increase the exploitable light for the plans...

metthc Posted January 22, 2013 Share Posted January 22, 2013 LST is very good to increase yield. A like it a lot. Link to comment Share on other sites More sharing options...
Elektroski Justovski Posted January 22, 2013 Share Posted January 22, 2013 Hahaha u are in very good mood today. 1 Link to comment Share on other sites More sharing options...
Guscode Posted January 23, 2013 Share Posted January 23, 2013 It's so awesome cause you encrease the usable Light. I love it too! But My actual grow are Automatics and with that genetics it's hard to train them well. You got no time... Link to comment Share on other sites More sharing options...
Elektroski Justovski Posted January 23, 2013 Share Posted January 23, 2013 All autos i see most of time are lst since to increase yeld, and they very fast tie down, just do this when they need water they more flexible like russian ballet dancers.

Big'G' Posted January 23, 2013 Share Posted January 23, 2013 So LST, FIM and supercropping are all the same..... Link to comment Share on other sites More sharing options...
metthc Posted January 23, 2013 Share Posted January 23, 2013 So LST, FIM and supercropping are all the same.....You can say, the same in final result? Link to comment Share on other sites More sharing options...
Elektroski Justovski Posted January 23, 2013 Share Posted January 23, 2013 Nope and yes, lst dont give so much stress to plants when fim and sc do but all is about height control and incrase yeld. Link to comment Share on other sites More sharing options...
Guscode Posted January 23, 2013 Share Posted January 23, 2013 That are all completly different technics. You harvest weed, but the plant looks different. And with this modify shape of the plant you reach different goals... Link to comment Share on other sites More sharing options...
