I am amazed with this so far. With this product when you plug it in the light stays on for 16 hours and off for 8, so they recommend starting first thing in the morning then the lights will be off when everyone is sleeping. I am still skeptical of the process. But after only 2 full days my lettuce is sprouting!!!! Whoop Whoop! Tomorrow I will plant the old fashion way...with soil. I’ll have to get dirty, not looking forward to that.
