Most grow kits look like lab equipment. This one looks like you meant it.

The Mason Jar Grow System is a modular hydroponic setup built into two standard mason jars. Water reservoir at the bottom, grow chamber at the top, connected by a 3D-printed threaded sleeve. Swap the rooting plate to change what you’re growing.

What’s in the kit:

• 3D-printed threaded connector sleeve
• 2 wide-mouth mason jars (16oz or 32oz)
• 1 rooting plate (herb, sprout, or microgreen)
• 1 net cup
• Quick-start guide

What you can grow:

Herbs (basil, mint, cilantro, thyme), sprouts (lentil, mung bean), microgreens (radish, pea shoots), leafy greens (lettuce, arugula).

Why it’s different:

No proprietary pods. No refills. No app. Clean lines, clear glass. Something you leave on the counter.
