You can hit 175M+ NW on alliance with an all-explore which isn't too shabby.
Depending on available targets and whether you get retal'd, exploring up to 10k acres is often comparable to grabbing in alliance. Granted, those who are willing to camp targets can do much better, but that's not really part of the fundamentals either.
In general, you should have enough tech from your tech start so that even doubling your land won't make too big of a difference to your tech levels, and your overall production should increase with more acres even if they are not built. Since you are a farmer, you don't have to worry about percentage based buildings like a casher would, so without doing any real calculation, I think it would be more productive to explore and then build the CS after while your income is slightly higher. It's probably a ~7% increase for each turn after exploring prior to building.
