What model is the v00? I have the par600. They're pretty solid. I only used it for veg. the viparspectras don't have alot of red. I've seen people do pretty decent in flower with it. Ultimately i would have been disappointed if I had higher expectations. Considering the hours of research put in to learning how to best grow these plants, spending a little more time learning how to build a cob will drastically improve your results. Another option would be to look at the conversion threads, and choose a cheap panel based on its upgradability.
