I am using this retro-white bulb right now. I am wondering if I should keep it throughout the grow or to put the old HPS regular in after the first couple weks of flower...wish I knew FOR SURE that this bulb is better than the HPS.
unless you want to experiment - i would stick with the tried and true HPS.
Also - how old is your bulb? I think you be changing out your MH every 18 months at least.
I have had this bulb for over a year but have only used it for 6 weeks so far. It may stay a little cooler than an HPS regular bulb but I am telling you all right now it still gets warm and this wll not be a miracle " summer bulb ".
The plants are diggin' the light, and I am glad I got this bulb instead of a standard MH, but definately no miracles here. I am going into flower in about 4-5 days and I'll decide what to do for lighting @ 2 weeks into flower. I will use this retro bulb for first 2 weeks to minimize stretch.
Is that the same thread were you told the guy that he shouldn't do it either? I think you said it was an experiment for you and only someone with experience should try it?.... um, here's actually exactly what you said. "I wouldn't rec' you do this unless you have good enough experience. i did it just to see if I could." yeah, that's the one.Yes... i answered one of your other posts where you claimed that one cannot grow in gravel.

I never said it was a miracle bulb but, what I have said a number of times is the it does the job of both HPS and MH bulbs for much less of a cost, the spectrum is better, the bulb runs cooler and works on a standard HPS ballast.
No point buying one then.
The only reason to want a better bulb in veg' is for faster growth.
I've been vegging two plants under UV 24/0 for 28 days. They are both showing signs of sex. One female and one male.
This is just with UV as their sole source of light.
I'll drink to that. I am happy with the bulb so far. According to the light spectrum graph it seems like this bulb is better than an HPS for flowering? I may just use it the whole time. I think my HPS bulb is more lumens though..
You mean you are using those funky blue UV lamps ?

So the lost lumens are made up by the light being closer... so, what? We end up where we started? Only paying a little extra for the bulb.
