When do you open the bag of the pile cover and take off the plastic wrap? I don't know what to do.

I'm a novice too, but according to the situation that I often go to the basin, the teachers' opinion is that the package can be unpacked at this temperature, and it is best to operate it on a continuous cloudy day. If the bud has come, it is best to put it in a ventilated place, avoid direct sunlight, and pay attention to spraying water to moisturize. If they don't germinate, you can remove the plastic wrap after touching the water and put it in a loose bag. The main function of bagging is to keep moisture and keep warm. Now there is no heat preservation problem at this temperature, so moisturizing is very important. That's how I operate at present.
