A tall and thick stem crowned by a beautiful, vibrant and colorful flower with rich yellow petals and a brown centre; no doubt, Sunflowers are most cherished by the flower gardeners like you and me! Apart from their rich, sunset colors, what attracts most growers are large blooms and seemingly endless benefits that these flowers give. Sunflowers can be easily planted from the seed and are available in different varieties. These flowers can be 3 feet tall and can develop big heads. There is one more type of sunflower, called as Giant Sunflowers, which can grow up to 20 feet tall with 2 m blooms. Isn’t that amazing what nature has got in her pot!
Flower gardening can be made easy and enjoyable with hydroponics. Hydroponics gives you the freedom to grow almost anything indoors or outdoors. Sunflower too can be grown hydroponically in a floating hydroponic garden. It gives reduced crop cycles and better yields as all the nutrients are provided to the plants, and hence, the plants can divert their energy towards more important metabolic process rather than wasting it behind searching for food.
While growing sunflowers in a floating hydroponic garden, you have to make sure of a few things. First is the lighting. Sunflowers require adequate amount of light. If you are growing outdoors, your locale should be well lit; if indoors, then make sure your grow lights are on and you are providing the right spectrum of light to your plants. Second most important thing is nutrients. Buy the appropriate nutrients package for sunflower from the market and do not over fertilize them. Too much nitrogen can lead to decreased oil content in the sunflower seeds.
As you are using hydroponics to grow sunflowers, you can float a support raft on top the reservoir. This support raft can be made up of foam. Fill your net pots with rockwool surrounded by silica stones along with the initially germinated sunflower plants. Place these net pots in the spaces drilled at the raft making sure that every plant bottom is well immersed in the nutrient reservoir. Once they start taking the nutrients, you can sit back and relax. Watch your plants flower. No need of pruning either, just a little support when they get bulkier and you’re done. Enjoy looking at them while growing and count time for reaping the desired harvest!
