When coir peat is compressed in 8:1 ratio, we get 650 grams blocks and these can hold more than 10 litres of water per block. These can be easily placed in small planters as they are small and water is added while fixing the plants. The advantage of using peat 650gms block is that it does not require regular watering. These are considered a better alternative than soil because of ease of use and they do not spill over as soil does.
