If you mean sunrise to sunset of 14 hours then it's iffy. Another reason to keep it taller since you want to have some nodes when she does go to flower.I only have one light so I’m unsure do I keep them all outside and use the tent to assist Lucky in veg? What ever I top I’ll try and clone. Is 14 hours of natural sun enough to keep them in veg?!
Yes, alternating nodes happen when a plant is ready to be flipped, or reached maturity. They grow identical nodes up until that point.
