If you're unconcerned about the company's demise and are able to get an AeroGarden cheaply, don't expect to get any customer support past that 90 days.
Of the three AeroGardens I owned, only one still functions normally. A Bounty Elite model I owned developed problems with its LED lighting, and since the device was out of warranty, the company told me it couldn't repair or replace it.
For the liquid nutrient, you can either stock up on large containers of the plant food, which contains 16 minerals, or use an alternative mix.
As long as your AeroGarden keeps working, you should be able to find supplies and parts to continue growing plants for years to come.
