I have been mass growing plants for quite some time now, and i have for the last 5 years gotten used to double growths on my plants without using fertile dirt, but now the glitch is up to missing seedlings, went to water my plants on day 4, and i now have 4 seedlings missing from their bowls. And no it is not in any particular area, i had lived in malas for quite some time and had double growths while there as well.
As you can see in the picture above the bowls are empty, they are all filled and softened before locking them down and raising them, to the height seen in the picture, then seeds are added to the bowls . And yes i am growing on multiple floors as you can see the spider trees and other plants from the floor below.
