This is what actually moves. Sorted by what customers buy most, not by what we'd like to push.

The reusable silicone grow mediums lead the list, which tracks with why we started making them. They replace grow mats and soil, wash off after harvest, and go back into rotation for years instead of getting thrown out every crop.

The 1020 heavy duty flats and complete kits come next, since most people need the tray and the medium together to get their first crop going.

Our free seeding guides sit high on this list too. Seeding rates are the number new growers get wrong most often, and the guides are free, so there's no reason not to grab one.

Further down are the courses, books, and DIY hydroponic build guides for growers who've gotten past the first few crops and want to scale up or build their own systems.
