There is no exact answer to this question, but there are some factors that play into it. The amount of water given to a clone at once will depend on how often it is fed, what its feeding schedule is, the type of food it is fed, and how much water it takes in naturally. The amount of water a clone requires varies greatly depending on its age. A 2 week old clone should be given between 50 and 150 ml of water per day. After 3 weeks of age, the amount of water needed increases to 100-250 ml per day. After 4 weeks of age, the amount of water needed increases to 200-350 ml per day. At 5 weeks of age, the amount of water needed is 300-500 ml per day. This amount of water should be given at least three times daily. The amount of water a clone needs is also affected by how well it is fed. A clone that is given a large quantity of food will require more water than one that is given a smaller quantity of food. If a clone is fed 1-2% of its body weight in food every day, then it will need more water than one that is fed 1% of its body weight.
