Fyi, I think vanilla plant is considered a terrestrial orchid so it might behoove you to put it in the ground and let it climb somewhere. I think that's what they like. Or maybe even in a pot with some very chunky soil and again, Allow it to climb wherever it wants to go.
So Many growers have attempted to grow Vanilla only to find out the 'cuttings' won't bloom until they reach 6-8' > Might be best to attach it to your pool cage frame & ignore it.
