I’ll be putting the lava on the bottom side for mine. But the farm will be at the bottom of my plots so it won’t fall on me when I’m placing it since I’ll be standing under my plots. Then I’ll likely put glass panes across it all then plot the section and won’t have the lava spilling out.
It looks so clean without the lava. Easy enough to do when the deco gravel is the bottom of the plot. Time consuming… yes.
