O.287 Doświetlanie roślin tropikalnych zimą, ile wat na 1 m2 ? Porady, obserwacje, lampy led

Summary

In this episode, the host discusses the challenges of growing tropical plants in winter, focusing on the need for supplementary lighting. The plants in question are demanding, mega-tropical varieties that require significant light to thrive, something that is hard to provide during gloomy, short winter days. The host shares experiences with various plants, such as black sapote, star fruit trees, and mangoes, highlighting their struggles to survive in artificial lighting and low natural light. The episode also covers practical tips on how to properly supplement lighting, energy consumption, and the importance of light intensity and spectrum for plant health.

Takeaways

• 😀 Providing light to tropical and exotic plants in winter is essential for their growth, as natural sunlight is often insufficient.
• 🌱 Tropical plants, especially those that bear fruit, require a substantial amount of light to thrive, which may not be achievable in winter without supplementation.
• 💡 Even with artificial light, plants like the black sapote are doing better compared to others, showing that not all plants are equally sensitive to lighting conditions.
• 🌞 Access to natural sunlight, particularly from a south-facing window, is ideal for plant health. However, most indoor environments lack this luxury.
• 💸 Exotic plants are often expensive, particularly grafted versions, and many die during the winter despite best efforts to provide artificial light.
• 🌧 The gloomy winter weather (overcast and short days) severely limits the amount of natural light, making artificial lighting necessary for plant survival.
• 🪴 Star fruit trees, despite being provided with additional light, still struggle in winter and show signs of weakening due to the lack of true sunlight.
• 🌿 Mango plants are challenging to grow in winter, especially in artificial light conditions, as they are sensitive to moisture levels and proper soil drainage.
• 🔋 To supplement light for plants, approximately 200W of LED energy is needed per square meter of plants to simulate sunlight effectively.
• ⚡ The type and intensity of light are crucial for plant health; for instance, LED lamps with the right light spectrum can make a big difference, though not all plants react the same way.

Q & A

What is the main topic of this video?

The main topic of the video is providing artificial light for tropical and exotic plants during the winter months when natural sunlight is insufficient.

Why is light supplementation necessary for certain plants during the winter?

Winter days are short, gloomy, and the amount of sunlight is minimal, especially in northern climates. For plants that require a lot of light, such as tropical fruiting plants, supplementary artificial light is necessary to mimic sunlight and ensure they continue growing.

What challenges do tropical plants face in winter, even with artificial lighting?

Despite artificial lighting, tropical plants struggle in winter due to insufficient light intensity, lower temperatures, and the lack of real sunlight. Some plants, like star fruit trees, even with extra light, fail to thrive in winter conditions.

Why are some tropical plants, such as the black sapote, doing well under artificial light?

The black sapote seems to tolerate artificial light well, even with lower light levels. Its leaves remain green throughout autumn and winter, likely due to its adaptation to lower light conditions in the wild.

What is the issue with trying to grow star fruit trees in winter under artificial light?

Star fruit trees do not perform well in winter under artificial light, even with an LED lamp. They lose leaves and become weak because the artificial light cannot replicate the intensity and quality of natural sunlight.

What specific lighting setup is recommended for plants requiring supplementary light?

The recommended setup involves using about three 85-watt LED lamps per square meter of plant area. The lamps should be placed about 50-70 cm away from the plants to ensure adequate light intensity and distribution.

How much light do plants need in terms of energy for one square meter?

For one square meter of green leaf mass, approximately 200 watts of LED light is required. This is necessary to provide enough light for the plants to survive through the winter.

How does the human perception of light differ from that of plants?

Human eyes adjust to various light levels, making bright or dim environments appear similar. However, plants do not have this adaptive ability and need specific light intensity and spectrum to thrive, which artificial light often fails to fully replicate.

Why do mango plants have difficulty growing under artificial light?

Mango plants, especially those grown from seed, are very difficult to grow in artificial lighting. Factors like improper soil moisture levels in winter and inadequate light intensity seem to hinder their growth, leading to issues like leaf drop and lack of bud development.

What factors contribute to the success or failure of growing exotic plants indoors?

Success depends on the proper combination of light intensity, the right type of lamps (e.g., LEDs with various spectrums), correct humidity and temperature levels, and a careful balance of watering and fertilization. However, even with these measures, some plants still fail due to the absence of real sunlight.
