Your plants look a lot better than I would have thought they would, based on the 1st post in this thread, but they are doing well! At this point, I would recommend upgrading the lights considerably as they are good for now, but as the plants grow and develop a canopy, the light won't be strong enough to reach below the canopy, giving you a smaller yield than you would wish. Without the extra light, the existing light will support them but they will begin to stretch, needing a more intense light if they can find it.
