Up until early 2008, there was just 1 flagship model, the AeroGarden Classic (7-Pod). But now they have expanded their product line to include over 10 models with over 20 different color/ feature combinations. Here's an attempt to explain them all:

AeroGarden Pro¹⁰⁰ (7-Pod) - Black w/ Stainless Trim
The same as the AeroGarden Classic with Adaptive Growth Intelligence, which is a fancy way of saying it delivers the right amount of nutrients at the right times in the plant's growth cycle to optimize yield. It can be upgraded to "twice the light and twice the height" with the Deluxe Upgrade Kit.

AeroGarden 6 (6-Pod) - Black, White, Silver

It has been proven to provide 30% more growth as it delivers more oxygen directley to the roots. It also uses 2 flat grow bulbs to provide more light, more evenly to plants.

The Elite+ comes with the new Mega Cherry Tomato Seed Kit which grows fruit 3 times the size of regular cherry tomataoes.
