Nutrient increase is halved for bases without Aerospace Complexes, and cannot in any event exceed the size of the base
More nutrients equals more citizens, and more citizens equal a high final score, so a program of Sky Hydroponics launches is an excellent way to pump your late-game population if you're trying for a high score.
An interesting side to the Sky Hydroponics Lab is that, like the other Orbital improvements, its effect is limited by the size of your base, but its effect also diretly increases the size of your base. Fortunately for your sanity and the computer's processor, this effect is not open-ended. Since it takes two nutrients to support one citizen, there will come a point when your Sky Hydroponics Labs have enhanced your population as much as possible ( roughly speaking, this point is between 1.5 and 2 times your maximum base size without the satellites ). This is for bases with Areospace Complexes - bases without will gain even less, of course.
