Do you know how many watts that floro puts out? It should say on the bulb near the ends somewhere.

You see, if you don't have enough watts of light, the plants are going to continue to strect because they are hurting for more light. That's why we are wondering. The problem could continue if you don't have enough power.

But your plants are looking fine. Looks like stretching has slowed down some. Good job, keep us updated...peace
