Another way of planting if there is no much space for planting //Planting of jute leaves in a sack

I visited one of my friends house and I was fascinated the way he planted his jute leaves.

He built is house on just one plot of land and there is no much for him to do other things. I was surprised to see how he planted his jute leaves
He explained how he has been enjoying the jute leaves inside the sack despite he doesn’t have much space to plant.
He poured loamy soil inside the sacks and spread the jute seed inside and he keep wetting it morning and evening.
I guess such process is a very good one for people who doesn’t have much space and also if the soil they have is not that good because some people might have sandy soil which is not the best soil for planting.
I will be carrying out this type of experiment in my house.
