You can always buy AeroGarden Grow Anything kits, but it’s cheaper to buy the sponges, labels and nutrients separately, after you buy your first Grow Anything kit. You’ll often find this on sale.
You’ll need a lot of AeroGarden Liquid Nutrients if you are growing your own seeds. Especially if you have more than one garden. Buying it one litre at a time is a great cost-saver.
Price is in Canadian dollars. The link will take you to the Amazon Store of your country.
