Oasis Horticubes Grow Cubes 104ct Sheet
Best hydroponic medium for efficient, sterile seed starting and propagation.
Optimize your hydroponic seed starting with Oasis Horticubes® Grow Cubes. This 104-count sheet is engineered for efficient germination of vegetables and herbs, offering superior drainage for an ideal air-to-water balance that minimizes algae. The low-density foam promotes robust root growth without compaction. Arriving sterile and pathogen-free, these cubes reduce disease risks. Pre-dibbled holes ensure uniform seed depth and spacing, while the pre-scored sheets allow for easy separation. Designed to fit standard "1020" trays, they simplify your propagation process.

What customers say
Horticubes are highly valued by growers for their superior consistency and ease of use. The preformed cubes simplify seed starting, eliminating the mess of traditional methods. A key benefit is the foam's exceptional moisture retention, creating an ideal environment that supports high germination rates and robust seedling development. Users consistently report excellent success and healthier starts compared to alternatives like rockwool or peat. While performance is praised, some find separating the 104 cubes from the sheet occasionally tedious. Overall, the product earns high trust as a reliable, high-performance tool delivering predictable results.
Know before you buy
Yes, it is recommended to soak the Horticubes in water until they are fully saturated before placing your seeds. This ensures the medium is properly hydrated to support initial germination.
No, these are designed as a single-use medium. Because they are made of foam, they are intended to be used for one growth cycle to maintain a sterile, pathogen-free environment for your seedlings.
Yes, the sheets are specifically sized to fit standard 1020 trays. You can place the entire sheet directly into the tray for a seamless setup.
While optimized for hydroponic systems, you can transplant these cubes into soil once the seedlings have developed a strong root system. The foam will not hinder growth, though you should ensure the cube is fully covered by the soil to prevent it from drying out.
The sheets are pre-scored, allowing you to easily snap or pull them apart. This makes it simple to remove individual seedlings as they reach the transplanting stage without disturbing the root structure.
These cubes are inert and do not contain added nutrients. You will need to provide a nutrient solution once the seeds have germinated and the first true leaves appear.
