thank you very much.7 days in soil. first 3 days grows well. but next 4 days not growing. I use sunshine and normal light.i had watering 2 times.Are we talking seven days from germination or seven days from the time they penetrated soil? If the first, they look pretty good and healthy. Tall stretchy plants are never good. The plants look good and green so far. What type of lighting are you using? What about watering schedule?
