Father and law does the whole grow with a MH and gets about a QP per plant. Some old school growers use it threw the whole grow all the time. I got 2 1k MH balasts from a guy that had about a 6K set up and all he used was MH for years, about the last 15 years. I would recommend a HPS, but I am just giving examples of people who still go that rout the whole grow. Give us the results.
