Please allow me to make a sad expression. The cactus is roasted in summer.

The seeds were collected a few days ago. But I didn't go up because I was not free these two days. When I went up yesterday evening, I had the heart to get out of the pit. It's ripe in a large area. (thanks to hb33 for the material)

My ball is in the sun all the time, so there is no problem with sun resistance, but there is nothing I can do when the temperature reaches the critical value. It is cooked directly. Just for a moment. There is no hope of salvation.

The day before yesterday also boasted that next year to see the seeds to change a good bike, the result. Now there are many mothers without them. The key is the mother. It's hard to get it now. It is also the painstaking effort that I have collected over the years. It's really depressing.

Problem: high temperature. The temperature of 60 +.

Many friends will say that Dapeng on the ground has no problem in the open air. Yes, my open-air dragon claws are fine, the ground shed, because close to the ground, heat dissipation will be much better. Mine is on the roof. There is thermal radiation on the roof, so the temperature is really high. Turn on the fan will basically be in more than 50 degrees. Not one, but seven. My shed is not sealed, all around is open, but it is so hot.

In fact, the sun in the open air will not be so hot, and the roof and floor is only 52-53 degrees. Will not go to 60. But... If the fan in the shed is not on, it will be 60 +.

Why did something go wrong?

I don't know why Xiaomi's automatic switch failed. It didn't open yesterday. (2 sheds, two switches, of which the main shed is not open), the seedling shed is open, the temperature is more than 50 degrees. But Miao is all right. There is also temperature control and the police, but I didn't check my phone.. In this way, it happened perfectly.

Of course, I do not have sunshade, if shaded, the temperature can be several degrees lower. It should not be so serious. But because I've been out of the sun for 6-7 years. They all got through it safely. It's not just this year. So I missed it.

Look at the picture. Chile, dragon claws and ball fans are all ripe (nothing happens in the open air).

Some of them were photographed when I was harvesting seeds, one day after another. Heaven and earth..

The balcony is open and the sun is fine.

The roof and the floor are in the direct sun, and it's all right. (when the temperature is 53 degrees, all the fans are fine.)

This is the temperature of the shed yesterday (the temperature of the shed with fans). There is a fan, the highest is 55 degrees. It is conceivable that there is no fan

The ultimate reason: after closing on 29 th, there was no operation on 30 th. At 18: 38 on the 30th, I turned on the fan when I went up to the roof and found a problem.

Another figure: electricity consumption on the roof. 30, a lot less (because only 2 fans and other devices are on).
