My plants are 2 weeks old today and have been LSTed once and let grow up into a SOG/LST combo. I LST my plants from about the time they are 4-5 inches tall and then once a week (or shorter depending how fast they grow) to keep the canopy as low as possible. My last grow, despite an issue with cold temperature right at the end of flowering, was 5 plants and nearly 100 tops that yielded about 1.5oz each. Definitely would have gotton more had I been here to control the temperature swing. The nugs were all main colas also which was pretty nice. If youre thinking about doing LST, there are a TON of different methods and everyone has one they claim is the best. Personally I dont think it matters so much as to how you LST but rather that you do it properly. What youre trying to do is essentially the same as topping where you are redustributing the auxins from one growth shoot to several but without stressing your plants from cutting them. When I LST the first thing I do is tie a counter anchor around the main stem pulling the plant in the opposite direction you plan on LSTing to prevent your plants from pulling themselves out of the ground trying to correct the training (dont tie the anchor taught against the stem as it will eventually choke your plant as the stem gets larger). After I do this I have flexible stainless steel wire (you can use clothes hanges cut up as a substitute) that I fashon into a 9 inch strip or so with a small hook on the top of it. I use this hood to grab the main stem about an inch or two below the apicol tip and bend it far enough down to be below any other secondary growth spots. I usually bend the plant almost to the ground to allow the auxims, which regulates what growth tips become apicol, to fully relocate into the rest of the plant. After the initial LST you just wait until the secondary growths become 2-3 inches and then tie them down also until you have a very short, dense bush with several apicol colas (ive gotton 20+ per plant but ive seen people get up to 30/40). This method will allow you to maximize your light, space and control over the plants, which is essential for growing good weed. Also, because this is your first time growing keeping your plants short and stocky will definitely help you keep on top of any issues that might sprout up and go unnoticed if you had a 4-5 foot tree (nugs need to be tied up, finding any signs of mold or insects, ect). The one thing I will suggest if you do decide to LST is that you only grow LSTed plants. If you let one plant grow straight up it will push the light farther away from the LSTed plant and any benefits of having an even canopy goes to waste. Hope this helps somewhat, let me know if you have any questions!
