Suggestion

You're going to need to have CJB if you want pumpkin farming to make good money.

 

I used CJB, and had fly, and proper tools, and still couldnt make good moeny so i switch to melons

 

Absolutely nothing.
Farm a lot for a mediocre profit and buy fly, then you can farm a lot for good profit.

 

Hmm. Since this isn't going to happen would anyone like to help me install CJB? I have a PC and I have tried some many times, used so many different tutorials, that I just gave up.

 

Isn't the point of paying for fly to get an advantage to use in game?
