Growing Tomatoes Hydroponically is a suitable alternative to growing them in soil. In the same context, a looming question is: How long does it take to grow tomatoes hydroponically? This in-depth guide covers each crucial aspect, from growth stages to indoors cultivation tips.
How to Grow Hydroponic Tomatoes?
Use healthy tomato seeds for growing Hydroponic tomatoes. Growing hydroponic tomatoes from seeds involves several steps. These steps start by germinating tomato seeds in a nursery tray filled with a growing medium like rockwool or peat pellets.
Tomatoes require a stable temperature around 75-85°F (24-29°C) and also require to keep the growing medium consistently moist. But, after the development of true leaves, you can transplant the tomato plants from nursery tray into a hydroponic system, such as a deep water culture or nutrient film technique setup, with a suitable pH-balanced nutrient solution.
As the tomato plants are growing, so they require adequate light, either with high-quality grow lights or natural sunlight, for about 14-16 hours a day. You will also have to monitor the pH and nutrient levels regularly, and adjust their levels as needed. As the plants grow, support them with stakes or trellises and prune to encourage proper airflow and fruit production.
With these steps, you can successfully grow hydroponic tomatoes from seeds and enjoy fresh, homegrown tomatoes throughout the year.
How Long Do Tomatoes Take to Grow Hydroponically?
Tomatoes grow well in tropical and temperate climates in soil. Even more, tomatoes also grow well in hydroponic environments.
They grow in 7 stages, from seed germination to harvest, which takes 8-17 weeks. These stages are linked to tomato variety, nutrient availability and optimum conditions.
How to Start Tomato Seeds for Hydroponics?
Germination Stage: (Days 1-7)
Plant tomato seeds in a germination medium or a seedling tray with a suitable growing environment. Tomato seeds typically germinate within 5-10 days.
Seedling Stage: (Days 8-21)
When the seedlings develop their first true leaves, they are usually kept under fluorescent lights or in a greenhouse with controlled temperature and humidity.
Transplanting Stage: (Days 22-30):
When the seedlings show up few sets of true leaves, subsequently transplant them into the hydroponic system. Carefully place the roots into the hydroponic medium or system.
Vegetative Growth Stage: (Days 31-60+):
During this stage, the plant focuses mainly on leaf and stem development. Maintain the nutrient levels higher in nitrogen to promote foliage growth. At this stage, plants may need support structures as they grow tall.
Flowering Stage: (Days 61-80+):
Flowering stage marks the development of flower buds, and the plant transitions from vegetative to reproductive growth. This stage demand energy, therefore, the nutrient ratios may shift to encourage flowering and fruit development. When the flowers are fully developed with their sexual parts, i.e., androecium and gynoecium, pollination may be required if not using self-pollinating tomato varieties.
Fruit Development (Days 81-100+):
Tomatoes start to develop and grow in size. This growing stage, requires adjustment in the nutrient levels to support fruiting with an emphasis on potassium and phosphorus.
Ripening (Days 101-120+):
Tomatoes gradually change color and mature. When the tomatoes reach the desired ripeness, harvest them.
