Cara semai pakcoy di rockwool - Anti kutilang Hidroponik

Summary

In this video, the process of growing pakcoy seedlings in rockwool is demonstrated, starting from seed preparation to transplanting. The presenter explains how to soak pakcoy seeds, set up a nursery with rockwool, and carefully plant the seeds in pre-made holes. Techniques for ensuring fast sprouting are shared, including covering the seeds with black plastic to accelerate germination. As the seedlings grow, the presenter emphasizes the importance of sunlight exposure and proper watering to avoid damage. By the third or fourth day, the seedlings show healthy growth, ready for transplanting. The video concludes with encouragement to subscribe for more hydroponic tips.

Takeaways

• 😀 Always use good-quality pakcoy seeds for better germination.
• 😀 Soak the seeds in water and discard any that float, as they are likely not viable.
• 😀 Use a tray with low walls for easy handling and good air circulation.
• 😀 Rockwool is an ideal medium for pakcoy seedlings; cut it into small pieces but keep them intact.
• 😀 Poke holes in the rockwool for planting the seeds, ensuring the holes are deep enough for the seeds to settle.
• 😀 Wet the rockwool, ensuring it is moist but not waterlogged, to create the right environment for seedling growth.
• 😀 Plant one pakcoy seed in each hole and gently press it down to ensure good contact with the rockwool.
• 😀 Cover the holes with a stick or similar object to prevent pests and encourage faster germination.
• 😀 Use black plastic to cover the seedlings overnight, speeding up sprouting and ensuring a humid environment.
• 😀 Expose the seedlings to sunlight the next day for at least 4-5 hours to prevent etiolation.
• 😀 Keep the rockwool moist by flushing it with water from the sides, avoiding direct watering on the seedlings.

Q & A

What should be done to ensure the pakcoy seeds are of good quality before planting?

Before planting, soak the pakcoy seeds in water and stir the water. Any seeds that float are usually of lower quality and should not be used for planting.

Why is rockwool chosen as the seedling medium?

Rockwool is chosen because it retains moisture well and provides a stable environment for seedling growth. It is also easy to manipulate into the desired size and shape for seedlings.

How should the rockwool be prepared before planting the seeds?

The rockwool should be cut into small pieces and pierced with a stick, pencil, or chopstick to create small holes for the seeds. After that, it should be lightly wetted but not soaked in water.

Why is it important to cover the rockwool holes after planting the pakcoy seeds?

Covering the holes helps prevent pests, like ants, from taking the seeds. It also creates a more favorable environment for the seeds to sprout quickly.

How long should the pakcoy seeds be kept in the dark under plastic for optimal sprouting?

The seeds should be kept covered with black plastic for one night. This helps them sprout faster by retaining moisture and warmth.

How much sunlight is recommended for pakcoy seedlings after they sprout?

Pakcoy seedlings should be exposed to at least 4-5 hours of sunlight a day. Full sunlight exposure is ideal for healthy growth and to prevent issues like etiolation.

What is the recommended method for watering rockwool after planting pakcoy seeds?

Water the rockwool slowly from the sides or edges to avoid disturbing the newly sprouted seeds. Direct watering can damage the sprouts.

What should you do if the pakcoy seedlings appear yellowish instead of green?

Yellowing leaves may indicate unhealthy seedlings. This can be caused by improper water levels, poor sunlight, or other environmental factors. The seedlings should be monitored and adjustments made to care practices.

When is the best time to transplant pakcoy seedlings?

Pakcoy seedlings can be transplanted when they develop their third leaf, though the fourth leaf is typically a better indicator for transplanting.

How often should pakcoy seedlings be watered to maintain proper humidity in rockwool?

Pakcoy seedlings should be watered every evening to maintain humidity in the rockwool, especially after exposure to sunlight, which can cause the rockwool to dry out.
