It's official. I heard it from a supplier and went to double check the information. What can we do now to prepare? First, I'm going to talk to you from the retail side and tell you about three scenarios that could play out. Then I'm going to give you some suggestions.
Scenario 1: Liquidate now
In this scenario, the supplier has already announced they are closing. The seller wants to go ahead and clear that space for new merchandise. So they will slash prices in the hopes of doing just that. I haven't seen any major retailers doing that just yet, but I have seen a handful of third party sellers and individuals on eBay doing just that. So go ahead and scour the internet. Some of the eBay sellers are even offering freebies or selling 2 items for the price of one to sweeten the deals. Some are also offering "expired" pods at half price as well (more on that in a bit). So if there is an Aerogarden preseeded pod that you've always wanted to try, or if there's one your family likes, this is a good way to go.

Scenario 2. Liquidate later
The second scenario that could play out is, since Aerogarden stated they will close as of January 1, 2025, retailers will wait until we get closer to that date or even let that date pass before they reduce their prices. The prices will remain at the regular price until we get closer to January 1, and then we will see more sales on Aerogarden products. Again, this can be a good way to go, provided that they haven't sold out of that particular one.
Scenario 3: The hybrid of sorts.
This is where some retailers liquidate now and others liquidate later. Currently, if you throw in all the mom-and-pop shops and online sellers, this is what I'm thinking will eventually happen. That being said, it's not going to hurt to start scouring the internet now.

Now let's talk about those preseeded pods that "expired." If you look at the side of the Aerogarden pod kits, there is a sell by date and an expiration date. Some sellers will give you the expiration date at the point of sale and some won't. You don't really need to worry about it too much. I've gotten some preseeded tomato pods that expired 2 years ago and they still produced. I write the expiration date on the front of the package to help me keep track of it two ways. That being said, there are some sellers that are selling preseeded pods that are several years old. Those are the ones that I'd be leary of. However, those preseeded pods might still be of some use. Remember they send you free plant food and reusable items. If I were purchasing them, I might see if I could get them to come off the price if they were asking full price (you can do this on eBay).
Finally, there are other pod manufacturers out there. You will see lists of them come up in eBay, walmart.com, Amazon, et cetera. They're just not preseeded. However, it's not hard. If you remember my previous discussion on hydroponic systems, I've been making my own pods for years. In fact, I'm growing swiss chard in my iDOO hydroponic system now, and these are from pods that I made.
Now as for my Aerogarden favorites, my plan is to get them now and try to save seed from them or find a seed available. For instance I've saved tomato seed. We like the Aerogarden yellow tomatoes so I'm going to see if I can save seed from them, but I read elsewhere that this tomato is actually the canary yellow tomato. I've never grown it from seed without the hydroponic system as the thrust of our tomato "operation" are Arkansas Traveler, Cherokee Purple and Yellow Pear tomatoes. But I'm willing to try to see if any of my suppliers has it available to try. I've found one that offers a similar tomato (Tiny Tim), but I haven't found any canary yellow yet. And when I tried Tiny Tim, nothing happened. That was the week my old system failed so that could have done it too. I do have some seed left so I'll try again.
Now let's talk about returns. Hopefully you won't feel the need for it but if you do, here are some things to keep in mind:
1. With Aerogarden going out of business, your chances of your return being accepted and processed are not that great. That being said, Aerogarden has stated that they will offer support for a time after the sale. I'd see what they have to offer before returning it. If they can't return it, salvage what you can. I was able to salvage the resevoir (for another project), baskets, covers, and grow domes from my LaGute.
2. Remember that the retailer themselves might have different policies regarding returns. Some retailers may take them back. Others may say that you have to exchange it for another hydroponic system of equal or greater value (you will pay the difference), and others may not take it back at all. Whatever you do, abide by the policy. Don't assume you know. For that matter, don't assume I know because it can also vary from one location to the next.
Hopefully this will help you ease into the post-Aerogarden era. Whatever you do...happy gardening!
Update: Aerogarden has changed their minds for now. They have decided not to close at this time. But I am keeping this article up in the event they or any other supplier should close. The point is look at your options.
