I just had a question about some plumeria seeds I just planted. I planted them on dec 1 so they are about 2 to 3 inches tall. I live in north Texas so it gets cold. Im growing them im my closet under grow lights. They have been growing great and I have not shut off the lights yet. I have to go out of town for 9 days. Will they be ok without light for those 9 days and no water ?
