Germinate seeds hydroponically

it has several advantages over land use. Many common diseases can be avoided because the hydroponic medium is clean, while the soil can contain fungi or insects that can damage vulnerable seedlings.

The area where hydroponics really shines with land use is growing environment control. With hydroponics, the gardener is no longer at the mercy of the water or nutrient content of the soil. Every aspect of the plant's growing conditions can be controlled by the grower, not by Mother Nature. This can be a great advantage for young seedlings because they will get the right nutrients early in life, leading to much healthier plants in the long run.

Choosing a growing medium to germinate seeds

Rockwool cubes

As they germinate, the seeds require both oxygen and water to sprout. Porous media like perlite, rock wool, or vermiculite will do this in addition to having great drainage capacity. Rockwool cubes can be used for quick setup and easy transplantation as the seeds sprout and grow into full-size plants. Just place a larger cube around the cube that holds the plant. The roots will expand and grow through both rockwool cubes, allowing your medium to easily adapt to the size of your plant.

Perlite is another good growing medium for seed germination because its porosity allows good drainage and oxygen availability. Just be sure to use the garden grade perlite rocks and not the finer grade masonry quality powder. Plant your seeds half to a full inch deep in the pearlite medium and cover them with a thin layer of pearlite. The easiest way to set up a perlite seedling tray is to use a plastic tub or similar container covered in black plastic to make sure light doesn't penetrate the roots of your plants. Add a drain hole about an inch from the bottom of the container to cycle your nutrient solution while keeping a minimum level of solution available to plants at all times.

Nutrients to germinate seeds

Orchid seeds

Many seeds contain nutrients within their shells to provide the initial food to boost the germination process. However, this is not true for all species. Orchid seeds, for example, contain very few nutrients, so be sure to research your particular plant before setting up your garden. To avoid stressing the seed at a vulnerable point, it is best to use a medium that is pre-prepared with a low concentration of nutrients. The first initial waterings will give the seeds a small dose of nutrients until they are ready to absorb more. Once the plants have developed strong, healthy stems, you can switch them back to your normal feeding and watering schedule and use your seedling tray for the next batch of germinating seeds.
