There's no proof that running 24/0 instead of 18/6 gives you faster growth. Actually plants can get tired of constant light and really benefit from a few hours rest. I've always ran a 18/6 light cycle. And it helps your lights last longer and also lowers energy costs. And anytime you can increase the longevity of your lights and save money without affecting the plants its a good thing. Looking good. Do them lights not daisy chain?
