Week one is mostly about not overthinking it.

You fill the bottom jar to the fill line, drop in your rooting plate, scatter your seeds or set your seedling, and then you wait. The urge to check twice a day is normal. The actual job is: top up the water when the level drops. That’s it for the first week.

What we saw on day 3: tiny white root hairs starting to appear through the net cup on our basil cutting. It’s subtle enough that you might miss it. It’s also the first confirmation that the system is doing what it’s supposed to do.

By day 7, the basil had visible roots reaching down toward the water reservoir. The mint was slower — mint always is — but there was new leaf growth at the top. The radish microgreens were already 2 inches tall.

Week two is when it gets interesting. The roots hit the water and you start to see above-the-line growth accelerate. That’s when you can feel the difference between soil growing and hydroponic growing. Soil-based herbs inch. These ones jump.

A few things we learned the hard way on the first round:

• Don’t fill the water all the way to the rooting plate. The roots need some air exposure at the top. Leave a half-inch gap between the plate and the water line.
• Light placement matters more than you think. We tried a north-facing windowsill first. The growth was noticeably slower. South-facing windowsill or a basic grow light changes the timeline meaningfully.
• Smell the water if something seems off. Clear water with a slight green tint is algae — not harmful but a sign your setup is getting too much direct sun on the reservoir jar. A piece of dark tape around the bottom jar stops it.

By the end of week two we had our first microgreen harvest. That alone makes the setup pay for itself faster than you’d think.
