Never tried growing auto flower inside but I know someone that has two plants that are about 2-3 inches tall and have not grown any leaves other than the top two. They are useing leds that are about 5 inches above the plants. They leave the closet door open all day with good evening sunlight and the plants under the leds 24 hours a day with constant breeze on them. They have not ever saw plants this tall without a second set of leaves. any ideas or his he too impaitant. The plants are about 6 days old
