All AeroGarden models aside from the AeroGarden sprout can grow dwarf tomatoes. If you’re looking to grow big heirloom tomatoes it's best to use the AeroGarden Farm. This model allows for taller plant growth under the lights which is needed for the tomato plant to thrive. The Miracle Grow seeds that the AeroGarden uses are selected for growing in small spaces. These “dwarf” varieties are genetically chosen to remain compact in your growing space. If you are looking to grow large heirloom tomato plants then the AeroGarden Farm is your best bet due to the spacing of seed pods and height of the LED arm.
