Hi OrionGrowgul
We top most plants after the second shoot, so we start with four shoots.
It depends a bit on where you want to go. If you're planning a longer growth phase, you can also top them later. For bending the plant shoots down, we recommend a sturdier, slightly more stable plant wire. You can see it in our two current Skywalker OC and Sour Jealousy Growdiaries. Hope we could help. :-)
