It's nearly impossible to have a that small velocity midair because of gravity and you cannot simply hover somewhere. Make sure the player cannot abuse a feature that freezes them midair.
You might want to adjust 0.05 to a value that works better, find that out by testing.
Hacks/mods would be an exception obviously.

You could also make it so that planting is only possible while crouching (crouching isn't possible when not standing on the ground):

if(GetPlayerSpecialAction(playerid) == SPECIAL_ACTION_DUCK)

Or both.
