I think the light you picked was a smart choice, considering the options. I didn’t pick such a smart choice when I started.
If I were in your shoes right now I’d probably finish this grow with that light and see how it goes. That being said, when I was in your shoes, I ended up buying a second light about halfway through flower and finishing that grow with it, then using both of them through veg on my second grow before building out my own LEDs with @dbrn32’s help…and now I have two tents. Heh.
Anyway with the one light you have you’ll get to harvest and have plenty of good cannabis flower as a result, IMHO, but your weight might not be where it could be with a little more juice. This hobby (especially the indoor variety) has a way of being a serious money pit, so having a game plan is a good way to try and keep it under control.
And as always it depends on how much money you have.
