Farmer John was interested in growing larger pumpkins. The annual village festival was soon approaching, and Farmer John wanted to win the biggest pumpkin contest. He read an advertisement that stated the product “Pumpkin Grow” would grow larger pumpkins. His friend, Farmer Fred, told him “Miracle Pumpkin” would grow the largest pumpkins. He added “Pumpkin Grow” to 10 pumpkin plants every day for 30 days. He added “Miracle Pumpkin” to another 10 pumpkin plants every day for 30 days. He didn't add any product to the other 10 pumpkin plants. All plants were grown in the same soil and received the same amount of water each day. He measured the height and circumference of the pumpkins every two days. What was the control group in this experiment?
