When he had been busy , the notebook on the table had closed shut. Daichi opened it on the right page again and read the instruction. Check..check..done that..oh! watering!

The Slytherin flicked his wrist and his phoenix feather core wand fell out of its holster and in to his hand. He was about to point the wand at the pot and cast the Aguamenti spell when he remembered that his Aguamenti blast was too strong and he couldn't control it. So basically he was afraid that he would destroy the pot. Sprinkling in the air wasn't going to do much either cause that was going to take time and he would accidentally spray water on other students.

Having an idea, Daichi bend down to open his school bag and took out his own personal cup he had to use during the year. Placing the cup on the table but still holding it steady, he pointed his wand inside and said. "Aguamenti!" Water spurted out of the wand and it filled the cup rapidly. In only two seconds Daichi said "Finite" to stop the spell and looked inside the cup. It was filled to the brim.

Seeee the pod would have drowned had he not done this! He picked up his cup and carefully watered the potting soil.
