    For this purpose, use 5 grams of TRUE HYDROGEL for 1 litre of soil. But make sure that enough space should be left for planting the plant in the pot or hole as obviously the dry granules when added into water swell up to a size much more than their original size, therefore, keeping a margin of 15% to 20% is a must.
