Pros:

• love that it is modular so you can choose how big a 'farm' according to your budget
• love that it encourages people anywhere to grow - this can include schools or even old people's homes...
• love that it can fit into a small place like a flat or even a small house.

Cons:

• relies on having access to electricity (though probably it can be connected to solar as well)
• works out more expensive than having your own set up - but if you don't have a choice at least it's something
