Green Fingers

Choose the amount of liquid from each bottle you would like to feed to the growing watermelon.
Can you grow a record breaking watermelon?

This is a fascinating puzzle that requires patience and a logical strategy. The objective is to specify the amount of liquid from each of the three bottles, when administered together to the growing watermelon, will have the greatest effect. What is the largest watermelon that can be produced? You can earn a Transum trophy if you can cultivate a record breaking specimen.

There are no labels on the bottles indicating what is inside. We suspect that the bottles contain different types of fertiliser but we have no idea how much of each of the liquids you should use. We do know however that too much from any one bottle may have an adverse effect.

A 'trial and improvement' strategy is called for to successfully complete this thought provoking challenge.

Congratulations you have produced a record breaker.
