The prediction Redi made was that Maggots weren't going to rise on the jars fully covered, he wasn't a scientist that actually suported the hypothesis that life was generated spontaneouly, that's why he made this experiment.
Although many scientists didn't agree with him, it was a very importante experiment for the new hypothesis to come because he was one of the first ones to present it to the world. The hypothesis accepted for some people at that time was that life could rise spontaneously because of rotten food. To prove them wrong, Redi took 8 jars containing meat inside of them, half of them were fully sealed, and the rest was let into the open air. You know what happened right? The ones that were sealed didn't grow up maggots, but the others did.
This is called an uncomformity.
