Planting Process
Tenlead Growing Seed Cubes are a great option for planting veggies in a hydroponic system. They will ensure that the plants get enough water and the roots are able to grow properly.
Please follow our video to sow seeds, once the seedlings are growing out, you can either place them directly in the hydroponic system or use them as a medium to start your seedlings. Keep the cube moist and within a week or two, you should begin to see sprouts.
When transplanting the seedlings into the hydroponic system, gently remove the seedlings from the cube and place the roots into the designated spot in the system. Make sure the roots are fully submerged in the water to ensure proper growth.
