It was hard work for me, and I got sore muscles every day. So I thought gardening on the balcony would be easier than in a field, since planters aren’t heavy. It was hard to bring soil from the home center to the balcony, but using a rental field made it easier. I was able to bring a small amount of soil to sow seeds in pots on the balcony. At the same time, I discovered hydroponics through some books.
