Ok so this step is not really part of the build per se, as it is something you have to do on the plant few weeks after you’ve started.
You’ll know it’s time to do it when your plants will have reached there 3 node.
The “head” of the plant should be few cm of branch above the third node.
Take your plants out.
You should easily see the nodes.
Now you’ll have to pinch the trunk with your nails.
Remove the top-most side leaves, they’re hiding the light from the new main branches below.
You have something like this now.
Don’t remove the bottom-most leaves, but make sure they don’t overlap a new node.
Again, next plant.
Perfect ! So now our plants are both ready to go back to veg for 1 or 2 weeks, and then we’ll send them to flowering !
A week later..
You’ll quickly see a big boost in growth after topping, be sure to keep all the branches well spread.
Use some wire if they resist to much.
