How do I make upside down growing plants?

You can make that with cross model block, in update tick put with nbt tags or with randomizers something like:

if get block x y-1 z  = air

      Replace block with (your vine)

Also put in this procedure:

if get block x y+1 z  = air

      Remove block at x y z

So your vine can't float and it grows :')

could you send a screen shot of what the problem is and a screen shot of the entire procedure page?

I think you used other variables like event/target entity or similar in the block update tick you only can put block procedures or positions and world procedures

I use https://imgbb.com/ for all of my screenshots..  and for you problem witj the "you have selected a world trigger that does not provide the following dependencies" part... You are using the Event Trigger wrong,,  You need to leave that part as No Additional Trigger, then in your Plant you use it's On Update Tick.. And you don't use the Additional Generation Condition..  In the Plants Triggers section, there is the On Tick Update there, you need to ad your procedure to grow you plant there.

and "you have selected a world trigger that does not provide the following dependencies" means one of your procedure block can not be used with the Event Trigger, because it needs stuff that that item doesn't support, (i.e. Itemstacks, blocks, entity, world)

ignore previous post, spellchecked and added a word :D

and "you have selected a world trigger that does not provide the following dependencies" means one of your procedure blocks can not be used with the chosen Event Trigger, because it needs stuff that that item doesn't support, (i.e. Itemstack, entity, world)
