 On day 5, I started to see sprouts in the Miracle-
Gro pots 2 and 3
 On day 6, I saw sprouts in pot 2 of the Control and sprouts in pots 1 and 4 of Miracle-Gro.
 On day 7, I saw sprouts in all of the pots of terracycle.
 On day 8, I saw a sprout in pot 1 of Scott’s.
 All of the pots had either one or no sprouts.

 Miracle-Gro is the best for plants. This may be because it is enriched with several nutrients that are specially picked for plants.
 Terra-cycle is the second best fertilizer for Coriander and Scott’s is the second worst fertilizer for
Coriander.
 The control of no fertilizer did the worst. The plants didn’t grow much at all.

 I think that I could have improved by using temperature control. Since some of the pots were near a vent, It may have affected the outcome.
 Also, I think that I could have made more trials. I only did 5 trials for each brand and think that 7 trials could have bettered the results.
