Never germinated at all. Grow in a shallow box, indoors because I am in zone 7.
JoAnn Johnson from SC
Owner Response: Hi Joann, Here are some tricks for lettuce. Lettuce seeds go dormant when they are above 80 degrees Fahrenheit and will not germinate. Also, lettuce seeds need light to germinate well, so they must be sow on the soil surface or very shallowly, which also means they will need very regular watering to keep them evenly moist to ensure germination. A customer service agent will be contacting you to see how we can help troubleshoot the issue. Rest assured, our seeds are tested frequently to ensure they have germination rates that exceed industry and our own standards prior to packing. Happy gardening!

I have lettuce coming up! I have each plant (at about 4 inches tall) covered by a gallon plastic milk carton, so they don't get eaten. Plan to keep them that way until they're too big to fit. Is this ok?
Roxanne Turpin from CA
Owner Response: Hi Roxanne, Sounds like a great idea. The milk carton could create a greenhouse effect though which could cause the lettuce to get hot and bolt. A thermometer in the jug could be helpful to figure out if it is getting too hot (mid to upper 80s). Happy gardening!

Easiest head lettuce I've ever grown. Love this variety, in fact, I'm back for more just they're not available this fall. My family are not fans of leaf lettuces and actually ask if we have any Great Lakes ready. I'm succession planting to keep these babies going, trying a few methods to grow through summer too. So happy with these seeds and this variety.
