This is my first grow tying down the plants.
I used to just top once and flower, and the yield was better than not topping at all, but still lots of empty spaces in the canopy.
This time I topped once, and when the top two nodes of branches, that is 4 separate branches, grew about a foot tall or a bit longer, I tied them down with string so they were horizontal.
I drilled holes around the rim of the pot so I had somewhere to tie them to.
Then the lower branches grew up to their height, and if any grew higher then I would supercrop them, that is bend them horizontally.
So lot's more colas', and I'm avoiding the issue of harvesting the top 1/3 of the plant and having to throw the bottom 2/3 away as it was just popcorn .
But now I'm thinking instead of topping the plants, and then tying down the top branches horizontal when they grow big enough, it might be better to supercrop the main stem over, and this will have the same result of stimulating the lower branches to grow into main colas, and I also have the main stem as a cola as well, but it will be the same height as the lower branches.
Here's a pic of some Mr Nice Black Widow which had the main stem supercropped over three days ago.
It is supercropped over to the left in the photo.
You can see how the next branches down have now undergone a growth spurt because of it and are now becoming main stems.
It think this would be better than topping to increase growth of lower branches and reduce height of plants.
I wont tie down the branches on these ones as they are for clones, but if I was going to flowr them I would, to get a flat canopy.
