I tried Screen Of Green for awhile. It works but I am not sure that it is the best method for getting more quantity of buds. Since you asked )) the first thing I did was build my screens so that each plant had its own screen and that it was anchored to the individual container. I had come across way to many msgs and blog pages about ScrOG grows where the gardener mentioned problems like having to trim old leaves from below the canopy or even just doing basic maintenance. If the screen is anchored to the tent it is not possible to move the plant around once the grower starts to weave the stems through the screen.With that said, mind if I pick your brain and ask what you would do at this stage if the end goal is to ScrOG this plant?
Keep in mind that the 1-2 meter tall is what the breeder can get using their outdoor or indoor set-up. Their lights might be stronger or better. Most likely they are growing in larger pots whether it is soil or hydro and larger root systems tend to produce taller or larger plants. Just about every one of us will not get what the breeder gets the first grow we try.As mentioned above, I don't really have a lot of room to grow, maybe 70-80cm total, so there is no way I can just let her stretch out (seed supplier wrote 1-2M tall without any training). I was too unsure about LST in the beginning, so all I have done is top her above the 4th node.
The way around it is to grow the plant out to the sides and not up. If you topped once so far you should have two main growing tips. Using some of the Low Stress Training tip and bend those over and send each off to its own side.
Another thing to try is to let it grow up and then Super Crop the top if it gets to tall. Bend the top over using the High Stress Training of pinching, crushing and putting a sharp bend in the stem so that the stem is at a 90 degree over to the side. Some confidence and HST is easier to do than LST.
Or, shortly after the plant shows it is sexually mature put it into the flowering stage. Then if it gets too tall start training. You won't get as much since the plant will be smaller but it will give ideas to think about while starting the next plant.
