Cara Menanam Sawi Hidroponik Sederhana

Summary

In this video, Januari Nurhidayat demonstrates how to grow hydroponic mustard greens (Sawi Pahit) in a simple and effective way. The process includes sowing seeds in rockwool cubes, transplanting seedlings into a hydroponic system, and maintaining the plants with nutrient-rich water. After around 24 days, the plants are transferred to larger containers, ensuring they get plenty of sunlight. The mustard greens are ready for harvest in 35-45 days. The tutorial is easy to follow, making hydroponic gardening accessible for beginners.

Takeaways

• 😀 Sawi mustard is the type of vegetable used in this hydroponic planting tutorial.
• 😀 Start by preparing mustard seeds and cutting rockwool into small pieces with holes.
• 😀 Insert one mustard seed into each hole of the rockwool and cover the seed with a bit more rockwool.
• 😀 Store the seeded rockwool in a black plastic bag overnight to help germinate, and introduce it to sunlight the next day.
• 😀 After five days, the seedlings should have at least two leaves. If some seeds don’t germinate, it could be due to seed quality.
• 😀 Once the seedlings have four leaves, they’re ready to be transferred to a hydroponic system.
• 😀 Carefully cut and separate the rockwool cubes, ensuring that the roots aren’t damaged during the process.
• 😀 Place the seedlings into net pots with the roots pointing down and ensure they’re submerged in nutrient solution.
• 😀 Use an AB mix nutrient solution specifically designed for leafy vegetables like mustard sawi.
• 😀 After 24 days, when the sawi plants are larger, transfer them to a wider container for more room to grow.
• 😀 Keep the plants in a location with direct sunlight from morning to evening, and monitor the nutrient solution to avoid drying out.

Q & A

What type of mustard green is being grown in this hydroponic tutorial?

The tutorial focuses on growing 'sawi pahit' mustard greens hydroponically.

How should the mustard seeds be prepared for hydroponic germination?

The mustard seeds should be placed into small holes in rockwool blocks. After placing one seed in each hole, cover the holes and keep the rockwool moist.

What is the purpose of using a plastic bag during the germination process?

The plastic bag helps to create a warm, humid environment, promoting seed sprouting overnight.

How long does it take for the mustard seeds to sprout in this hydroponic method?

The mustard seeds typically sprout within 5 days.

What should be done when the mustard seedlings have developed 4 leaves?

Once the seedlings develop 4 leaves, they are ready to be transplanted into the hydroponic system.

What should be done carefully when separating the seedlings from the rockwool?

When separating the seedlings, it's important to handle them gently to avoid damaging or breaking the roots.

What is the purpose of using net pots in hydroponic planting?

Net pots are used to hold the seedlings in place, ensuring that the roots can grow into the nutrient solution, which is essential for plant growth.

How is the hydroponic nutrient solution prepared for growing mustard greens?

The hydroponic nutrient solution is made by dissolving AB mix for leafy greens into water. The concentration should be about 1000-1200 ppm for optimal growth.

Why is it important to replace the nutrient water weekly?

Replacing the water weekly helps to prevent the growth of mosquitoes and ensures the nutrient solution remains fresh, promoting healthy plant growth.

When is the best time to harvest mustard greens in a hydroponic system?

Mustard greens should be harvested between 35 to 45 days after sowing, or when the stems are still tender. It's important not to wait too long, as older plants become tougher.
