What customers say
Customers strongly endorse Oasis Horticubes as a premium, reliable choice for seed starting and cloning. The superior material quality offers an excellent balance of moisture retention and aeration, promoting rapid, healthy root development. Users appreciate that the cubes are pH neutral and easier to handle than traditional media, streamlining the planting process. The pre-cut sheet format adds significant convenience and ensures uniform cube size for consistent results.

Horticubes are viewed as a high performing staple for growers prioritizing reliability and ease of use.
Know before you buy
No, these are designed for single-use seed starting. Because they are made of a specialized foam, they are intended to be transplanted directly into your hydroponic system or soil once the seedlings are established.
Yes, it is recommended to soak the cubes in water, ideally adjusted to your target pH, before inserting your seeds. This ensures the foam is fully hydrated and ready to support germination.
Yes, the sheets are specifically sized to fit standard industry 1020 trays. You can place the sheet directly into the tray for a seamless setup.
While they are engineered specifically for seed germination, the pre-dibbled holes can accommodate small cuttings. However, ensure the cutting stem is stable within the foam to encourage proper root development.
You generally do not need to add nutrients until the seeds have germinated and the first true leaves appear. Using plain, pH-balanced water during the initial stage helps prevent salt buildup in the foam.
