Today we have observed that no seeds have germinated in acid media. Almost all the seeds grew only in water have grown. You can see the result in the table below.
We have a lot of small plants. We have divided them in two groups. One will be irrigated with water. The other one will be watered with a solution of acetic acid 1%, simulating acid rain. Next week we will see if there is any effect on the leaves and growth of the plants.
