I am still trying to find out more. Any idea if the grass fixed or glued to the floor like tiles or it can be easily remove in patches for washing? As it is kinda outdoor, i am also worry if there will be mold or algae growing beneath the carpet. Another fear is if someone eat at the balcony n drop some food or crumbles on the grass... how difficult is it to get rid of it... so it will not attracts insects?
