Thank you for sharing Aerobin which combines a lot of nice features in one bin. I am planning to buy one when Costco has a special. However, i have two questions about the earthworms shown in your video. 1. Did you place them inside or just showed up by themselves from the earth below? 2. The worms supposed to be difficult to survive under the temperature on the upper part having a temperature > 120F. The temperature profile inside the bin should gradually decrease until reaching to the bottom. Could you measure the bottom temperature to see if the temperature is adequate for their survivor so that the worms could automatically find a comfort zones above the bottom and continuously propagate? Is it possible that the worms trying to climb upward because of the temperature is not comfortable for them?

@@tdlin1721 I haven’t studied a lot about the earthworm. What I have observed that they are very amazing to survive in the bin. They come and go all by themselves. Sometimes they can be seen easily and sometimes they just hide in the deep soil. When the bin is wet, they could climb on the wall, and that is a reminder to me to add more brown things.

Thank you for your replies. In addition to the hot decomposing by aerobic bacterials, earthworms can also contribute significantly for the decomposition by digestion. The following was the result from my CharGPT inquiry: In hot composing bins, there exists a temperature profile from about 50-75 F to 150 F at the top, Can earthworms still survive in the comfort zone of the profile? ChatGPT Yes, earthworms can survive in the cooler regions of a hot composting bin where temperatures fall within their comfort zone, typically between 55-77°F (13-25°C). Here’s a detailed explanation: Temperature Profile in Hot Composting Bins Gradient: In a hot composting bin, there is a temperature gradient, with the hottest temperatures (up to 150°F or 65°C) at the core of the pile, and cooler temperatures towards the outer layers and bottom. Comfort Zone: The outer edges and bottom of the pile can often stay within a range of 50-75°F (10-24°C), which falls within the comfort zone for many composting worms, such as red wigglers (Eisenia fetida). Earthworm Survival Microhabitats: Earthworms will naturally migrate to areas within the compost bin where the conditions are suitable for their survival, avoiding the hot core and seeking out the cooler peripheries where temperatures are more tolerable. Moisture and Oxygen: These areas not only offer a more suitable temperature but also often have adequate moisture and oxygen levels, which are crucial for earthworm survival and activity. Practical Considerations Bin Management: To facilitate earthworm survival in a hot composting bin, ensure that there are cooler, oxygen-rich areas available. This might involve managing the pile to maintain a gradient and avoiding over-insulation that can cause the entire bin to overheat. Earthworm Health: Regularly monitor the bin's temperature profile to ensure that the outer areas remain within the optimal range for the worms. If necessary, adjust the bin's composition or structure to maintain suitable conditions. Summary Earthworm Survival: Earthworms can survive and thrive in the cooler outer regions and bottom of a hot composting bin where temperatures remain within their comfort zone. Temperature Management: Proper management of the compost bin can ensure that these cooler microhabitats are maintained, allowing for the coexistence of hot composting processes and earthworm activity. By maintaining a suitable environment within the cooler parts of the compost bin, you can successfully integrate earthworms into your composting system even when employing hot composting techniques.
Hello teacher, I am from Taiwan. The fig trees I planted grow very slowly. Is it because there is too much rainfall in Taiwan? What I would like to ask is how tall can the fig trees grow? Sorry to bother you.
@@lyyai What you said makes sense. Many other fruit trees in my country need to be covered with bags, otherwise they will be eaten by insects. Figs grow too high and it is really not easy to work.Thank you
