Modular Pot Stack

I charged straight from the water splitter over to a weathered cedar potting bench! Resting right on the rough timber was a tall stack of square green seedling pots—modular plastic blocks practically begging for construction! I holstered my pixel sword, grabbed the rim of the top container with both hands, and heaved. Pop! It slid free with a clean plastic squeak. I flipped two pots upside down side by side, aligned their bottom drainage notches, and dropped a third pot right over the center seam. To lock the joint rock-solid, I drove a flat wooden plant marker straight through the aligned slots like an interlocking crossbeam. Clack! Zero wobble. Two-tier garden watchtower officially assembled!
