How do I make kelp elevator without drowning?
I want to make a kelp elevator (with soulsand at the bottom and bubbles that lift me up) but to build it in survival I need to plant kelp from the very bottom (y -54) to the top (y 120) while being under water. I have no diamond armor with enchanting so I can't breathe under water and no potions either.
What can I do so I do not drown while planting the kelps to the top? I thought about placing a door but that would destroy the water from flowing down and I wonder if this might cause a problem with the planted kelps.
Any ideas? Also I have no time to build 2 blocks into the "wall" so I have a place to breath.
I'm on Java 1.19.
You don't need to plant kelp from the very bottom to top.
https://minecraft.fandom.com/wiki/Bone_meal can be used to grow kelp by 1 block on each use.
