Special Groups: Hydroponics
Planting Instructions: Lettuce and other greens thrive in cool spring and fall weather (50° F to 60° F). A few greens can handle summer heat, but most of them prefer the cooler temperatures of spring and fall. Most lettuce and greens can withstand occasional exposure to light frost but if very cold weather is coming, protect your plants with a frost cover.
Sowing: Prepare the seedbed outdoors using a hard tined rake, smoothening out the soil. Lightly sow and just barely cover the seeds with soil. Keep soil moist until germination is achieved. You can also start seeds indoors by sowing into seed starting trays using fresh new seed starting potting mix into clean seed starting trays. Just barely cover the seeds and keep well watered until they sprout. Harden off and transplant into the garden after about 3 weeks.
