Plant isn’t fenestrating

This can be caused by a few things:

1. If your plant is still young, or a starter, it may take a while for it to start producing leaves that fenestrate.
2. Your plant may also still be acclimating (or getting use to) it’s new environment.
3. It can be from too little light, make sure your plant is getting enough light to produce those fenestrations.

Note: Fenestration is produced as a plant matures and grows upwards. In nature, low light environments cause the plant to climb on other objects (such as other plants, trees, or mountainsides). Since the plant is trailing upwards and needs to give light to all of its leaves beneath, the fenestrations allows it to give light to those leaves.
