100 mL of water helps more mold grow rather than 0 mL or 200 mL. We tested how mold grows on raspberries depending on how much water it had. We only changed how much water each raspberry got so we could see how water affected the mold on the raspberries. On day 8 the raspberry in 100 ml of water was ¾ covered in mold. The other two jars were only ½ covered in mold.  This is because mold can not grow well in too much water or not enough water. It has been proven by farmers that too much water can kill corn, soybeans and many other plants, since mold is a living organism to much water can kill mold too so can not enough water.
