I think its good when you grow bio but ....
I Found this via google:
Plants' cell walls become swollen and rigid when the cells fill with water. In other words, the cells become turgid, or swollen and hard, when osmotic pressure builds in the cells. This action keeps the leaves of the plant from wilting and allows it to stand up in sunlight, biology teacher Nigel D. Purchon writes on his websute. Purchon adds that when a concentrated sugar solution is added, the cell walls shrink and pull apart from each other --- and the plant wilts. Sugar lowers the osmotic potential of the water present in the soil, making less water available for the plant to take in from the soil
