OASIS Rootcubes Growing Medium | 104-Cell Sheet - 1.25in - 8 x 13 Configuration

Cube-Cell Propagation Sheet for Unrooted Cuttings, 104-Cell

Unrooted cuttings need consistent moisture and airflow at the stem base to callus and root reliably, which is harder to guarantee with loose or uneven media. OASIS Rootcubes are manufactured in sheet form with individual cube-shaped cells, giving every cutting the same starting conditions across the tray.

This 104-cell sheet uses 1.25in cubes in an 8 x 13 configuration, sized to fit a standard 1020 tray, and holds a balanced amount of air and water along with starter nutrients built into the media.

Key Features & Benefits

• Sheet-form cube cells — 104 individually cube-shaped cells keep every cutting in uniform, consistent media.
• Standard 1020 tray fit — the 8 x 13 sheet configuration drops directly into a standard 1020 tray.
• Balanced air and water — supports a clean, healthy start for unrooted cuttings without waterlogging.
• Starter nutrients included — the media carries the right amount of nutrients for an economical propagation stage.

Frequently Asked Questions

What crops commonly use Rootcubes?

Poinsettias, geraniums, hibiscus, New Guinea impatiens, fuchsia, foliage plants, perennials, and woody ornamentals are common crops propagated in this medium. The uniform cube cells suit both fine-rooted bedding plants and larger woody cuttings.

What tray does this fit?

A standard 1020 plastic tray. The 8 x 13, 104-cell sheet configuration is sized to match.

Does it contain starter nutrients?

Yes, the media includes the right amount of starter nutrients for an economical propagation stage without needing a separate feeding regimen right away. That head start keeps early propagation simple before cuttings move to a full feeding schedule.

How do I know when cuttings are ready to transplant from the sheet?

Look for visible root development extending from the base of each cube before separating and transplanting. Pulling cuttings before roots establish risks damaging the stem-to-media contact that helped them start.
