Checked out that chart and it seems MH takes the win for UVB over CMH. Would it be worth swapping out my HPS for MH the last couple of weeks I wonder? Is that what guys use those 10,000K finishing bulbs for? My 1000W MH is 7200K and I'm not impressed with it's performance as a veg light but if it will juice up my trichs it might be alright. Cheap PlantMax bulbs and I have one in 400W as well.
Yesterday I tried an old SunMaster Warm Deluxe MH bulb I bought 16 years ago and it died after 1 1/2 flower grows. I now suspect it was a bad socket at the time. Been meaning to toss it out but glad I didn't now. Fired right up but sure doesn't seem bright compared to the PlantMax but it shouldn't I guess being more for flowering but with lots of blue so it's good for veg as well. I originally bought it as a flowering light to use with my 1000W MH mag ballast.
I have one of those cheap pH/light/moisture meters I'm using to check the intensity at 1, 2 and 3ft from the center of the bulbs. I know it doesn't really give me any usable data about the quality of the light but it does register intensity so that helps. Going to put the PlantMax back in today to check it and also check my Hortilux conversion bulb in the same ballast. Then use the HPS ballast to see how the EnerG Super HPS rates too. Nice to have choices.
