Process
To begin the planting process, simply take seeds and gently put them into the foam cube, making sure them are nestled deep enough inside to remain moist. Cover them with a layer to keep them to dark and moist environment and wait for the seeds germinating.
After germinating, put seedlings with the cubes into hydroponic system. When you add the foam cubes into the hydroponic reservoir, make sure that they are beneath the water line. The foam will soak up the water solution, and the roots will have easy access to the necessary nutrients allowing your plants to thrive. Phenolic foam can also provide better aeration since it does not become compacted the way soil does over time. Therefore, it allows the roots to breathe more naturally.
In general, Tenlead Cubes For Garden Growing are more environmental- friendly than other types of growing media used in hydroponics, such as rock wool or vermiculite. In fact, they can be biodegrade after using.
