Just traded about 7 grams for another 400 watt MH to add on to my current veg area. I got a standard blue spectrum bulb and an Ace HPS conversion bulb with the package (probably just keep this for a veg lamp though). The veg bulb has some carbon within the bulb showing it's been used during at least two harvests. Is there any simple way to visually tell if the bulb should be replaced, or will have to hook it all up and do a measurement with my meter. I didn't want to buy any new bulbs this weekend because I planned on buying a new glass bubbler, but I hate having nice hardware just lying around collecting dust.

The pics:

im no expert but if it was me id replace that, if my hps go like that i change the bulb and its supriseing how much brighter a new bulb is
i useully do 2 full grows and a few weeks veg with son-T but 1 ful grow if using a grolux or similar (they burn brighter but dont last as long )

does also depend on what your growing ie sativas the bulb might get 20 weeks use or like me with indicas about12-14 weeks per grow

hope this helps bud

The first pic is what I got laid out for the weekend. I'm off tomorrow so it's on. I'll be fiddling around on the computer for the next couple days helping my girlfriend write a massive paper for her Masters. Any help is appreciated, chances are I'l be grabbing a bulb in the next couple weeks, but I don't want to waste the juice on a bum bulb. Here's what I got comin' up in about 41/2 weeks......

I got a seperate 400 MH for vegging and a 1000 HPS for flowering. This was a deal I came across in hopes of using this fixture for a ScrOG grow seperate from my current setup. Now that I have it I don't know if it's worth using this bulb for flowering my ScrOG, or getting a seperate HPS system, like a 600 Watter, to flower my ScrOG grow.

I have all kinds of varieties under my lamps, thing is I only really use top of the line bulbs. I'm a little nervous putting a mystery bulb over my children.

I think you are right Twenny, th MH bulb seems a little beat up. The conversion bulb is still good though, does anyone know if they are as efficient as a true HPS bulb and fixture? They don't pump as many lumens as the standard bulbs in HPS systems do, but that doesn't always matter if the spectrum is right where it needs to be to flower. Any help is appreciated.
