Airships and hydroponic farms...

...no. Airships are *extremely" sensitive to wind. They could never promise delivery times that short when a bit of a gust on the atlantic could throw them absolutely completely off course. Airships can't start with "bad" weather. That is: slight winds. They cant land when there is wind. And many airships have been destroyed because of winds. Thats a fundamental problem that the hyperloop guys are going to fix just as much as they did fix the fundamental problems with the hyperloop.
These "fundamental problems" are not really problems for airships that only rarely touch down and can be loaded and unloaded with electric quadcopters which recently became available in suffient sizes.
Rigid hull airships regularly made transatlantic journeys with tight schedules, so your "gust of wind" problem is evidently wrong, and larger storms also effect airplanes starting and landing resulting in similar delays.
Those transatlantic journeys with airships are no longer done for good reason. And that would have to be a massive fleet of electric quadrocopters with an extreme lift capacity to load an entire airship. That sounds very expensive!
But I hope you're right, the idea is really cool!
Zeppelins largely fell out of use due to limited military application and because fuel was basically free back then due to abundant supplies. I think it is important to keep this historic context in mind.
As for electric quadcopters being expensive, yes, but the proposed business is end to end, so not like an airport that needs to be loaded and unloaded quickly with a large amount of cargo. So for the airships it will be rather pick and load individually replacing not only the airplane but also the trucks delivering the cargo to and from the airport.
It will likely need some good charging infrastructure on the ground to recharge these quadcopters, but the spread of electric cars makes this more realistic these days.
