Trying to find the best light set up for a medium sized grow cabinet, primarily for personal use. So crazy quick turnaround isn't a big concern. I've been looking for a switchable setup that uses one hood and one ballast, but can switch between HPS and MH for flowering/veg purposes in one cabinet (one at a time of course). I see ones that can just flip a switch on the ballast and swap out bulbs, and I've also seen the dual arc bulbs that a single bulb does both functions. Question is-what's the difference in the single bulb vs the two separate bulbs, and is there a difference in quality in the ballasts? Thanks!
