Ok I haven't started on the kelp farm but I did some redstone magic and now I can filter poppies and iron from my farm's output to make bone meal and iron blocks
I only carry good stuff on me when doing a project or returning from the mines. And all my gear is iron (iron farm in the spawn chunks) so if I die I more than likely would only lose a few seeds. Iron equipment dirt and water very stone and wood I'd be transporting
I only really need sugar cane for one thing and I'll probably have more than enough by tomorrow morning, I took a look a couple minutes ago and I think I already have like 20 of them
