If you get a tad tired of building/planting so many pumps, mutfruit and generators, try my CHEAT. It sets whatever item you've selected in the console to provide 50 more power, water and food. I've only tested it on generators (all of them), water pumps (all of them) and food plants.
It's easiest to do this while in workshop mode, as the item in front of you should be highlighted, but it isn't necessary. Get reasonably close to the item (so it's easier to select it), enter the console, left-click on the item you want to modify (the item code will pop up at the top of the console window, it usually has PP or similar after the code if you have selected the right item) and run the bat whatever command. Whatever being whatever you choose to name the text file you create in the Fallout 4 directory with the following contents:
setav 332 50
setav 331 50
setav 32e 50
setav 333 100
You can, of course, change the 50 for another number, but don't forget that Happiness depends on having Defence equal more than the sum of Food and Water (if my guess is correct). If I find the value for Defence (aka Safety, I think), then I'll advise.
setav 333 100 is defence.
