Looks good to me wat makes you think it didn't go well? As far as another light yes it will increase par but honestly I go by watts @ wall per size of space more light isn't always best and wat I mean by this is let's say you have a 2x4 you want 35w to 55w per square foot now for a 2x2 I would run much more than 200w the most useable par without co2 is like 900ish and under really anything over is just wasted @ that point. Now I'm not saying don't get another light bc it will help as you will be able to dim each one a bit getting a better efficiency aswell as a better spread of light which is why I personally think strip lights are the best as you can get 100% even coverage across the canopy with great penetration to the lowers aswell anyways like I always say if you have any ? lmk and I will do wat i can to answer or find someone who can, sending good vibes and karma and be safe.
