Sarah Corley Bio 105 Introduction: This lab was an experiment comparing Metro-340 planting mix and Walmart Earthgrow soil to see which one grew Wisconsin Fast plants better. The expensive grow medium, Metro-340 costs about $0.35 a pound, while the inexpensive grow medium, Walmart Earthgrow costs around $.08 a pound. We experimented to see which medium would grow the plants faster and fuller when the Metro-340 costs 5 times more expensive then the Walmart Earthgrow. This study is important to see if it is worth it to pay more for the Metro-340. Our hypothesis was if we plant the plants in both soils, Walmart Earthgrow and Metro-340, we expect the same amount of height. Methods: In the beginning of this experiment we filled two four inch pots with Metro-340 and Walmart Earthgrow soil. We then labeled two Popsicle sticks Metro-340 and Walmart Earthgrow so we could tell the soils apart. We misted the soils with a light spray and made two holes in the center of both pots. Seeds were planted in each hole and the soil was smoothed over. The pots were then
