Maverick wants to find out whether or not miracle grow really makes plants grow faster

He would have to stage an experiment. Use some pots with regular soil as well as some pots with miracle grow. Plant the same kind of plants and let them grow under the same light and wetness conditions. 
after a pre set time like a week or two for example. He then would check on the plants to see if the specimens in miracle grow soil did in fact grow faster. 
The answer is YES. I did that experiment this year in school :)
