Lettuce is traditionally a cooler weather crop. One of the GREAT things about a Tower Garden is that you can grow Lettuce, even in South Florida, in the Summer (click here to read our tips to help you grow through the summer). You find very few farms or families growing lettuce in the ground in Florida, in the Summer. So why can you do this in a Tower Garden? It’s all down to the 20 gallon reservoir! 20 gallons of water will never get as warm as the outside air temperature. You are literally cooling the plant from the inside out whenever the pump is running.
