MH Conversion Question

[Tommygirl]

Ok, I found a 400w HPS ballast that I can afford. At first I thought that it was a conversion ballast that will run either HPS or MH, but it turns out that it simply comes with an MH conversion bulb as well as a regular HPS bulb.

What I'm wondering is if that means that any MH conversion bulb can be run by any HPS ballast so long as they're rated at the same wattage, or is that too simple and cheap a solution to spreinging for either two ballasts or one of those really expensive one that will actually run both HPS and MH bulbs?

this is true however the bulbs are mega expensive compared to a regular MH bulb

here's a suggestion. you have an hps, right? yeah, ok, you can take off the ignitor and use it as a regular mh, if you want to go back to hps, put the ignitor back on.

here's a page that'll show you everything you need to know to become a ballast wiring pro:thumbsup: (and trust me, it's not anywhere near as difficult as it seems or looks.)

aflter converting my first, i found two more. i'd not have known to buy these babies (40$ for 2 400w mh lights!!!) otherwise, now i'm waiting on the ignitors to throw these in the mix too i've no need for mh, i veg with floro's quite effectively. but this goes to show you how a little work can be VERY rewarding!!

oh yeah, the article....

The hortilux ace is the best bulb out by far. Perfect ratio of frequency, some smart mother fucker must have designed that one. They must be owned by phillips in the Neterlands.

Why is your Hortilux Ace better than this SolarMax? They seem to be the exact same thing, except that the SolarMax works in an HPS system where as the Hortilux Ace works in an MH system.

I'm not trying to challenge you and say you're wrong, honestly. I'm asking a genuine question.

Another question. Which tend to last longer, the HPS conversion bulbs or the MH conversion bulbs?

why use conversion when you don't have too?

JUST TAKE ONE OF THE IGNITOR WIRES, CUT IT, WIRE EACH END TO A TOGGLE SWITCH, ($2.25), MOUNT THE SWITCH OUTSIDE THE BOX.

SWITCH ON, IGNITOR FIRES FOR HPS.

SWITCH OFF, RUNS MH.

SAVES YA HUNDREDS.

GOOD LUCK

before you go hacking on your ballast to install a switch would suggest you try just using the hps for veg and if you have got a mh conversion bulb well then use it but they are expensive, many will use a hps throughout the grow veg and flower, you wont notice that big of a difference between vegging with a mh or hps.
