need help with hps light system

[DarkHorse007]

hi guys been gone for a while had problems with my internet and it wouldn't load the site. ive been working on trying to switch my plants over to flower but im having problems. I had a big industrial shop light with a ballast on it that i planned on using to power my Hps light but when i got my hps bulb it did not work in it, and i noticed that there is a bit of a difference been the base of the hps bulb and the mh bulb provided. my question is is there a difference between the sockets of a hps and mh bulb and how do you growers who use both make them compatible with the same grow hood?

Dont know pilgrem what yual tryin do but mh bulbs need mh socket and ballast just as hps needs hps sockets and ballast never try to mix them friend! Now I do hear yual can buy "special" bulbs that can be used in either or but never try em. Others smarted be along trail soon enough good luck yur trail walkin pilgrem but be safe!

some only run MH some only run hps, and some run both. i think u might have bought one that only runs Mh

 

[DarkHorse007]

so am i safe buying any grow light hood then or do they vary based on types of bulbs?

 

[ShOrTbUs]

just make sure u get an electronic ballast. im 99.9% sure all electronic ballasts allow for MH & hps bulbs. magnetic ballasts are the ones u have to watch out for

sounds like you have a MH ballast and that wont fire a HPS bulb...is there any writing on the ballast?...what does it say...Bulb must match ballast...and if ya have a switchable ballast than there will be a switch on the ballast...but it sounds like you running a HighBAy light like Backwoodsdrifter?....

Bulb must match ballast...tha Mogals(sockets) are the same..its the plug into the ballast...

thanks guys think youve got it all figured out for me i went and took some pics also. i took some pics of the mh bulb that came with the light and the hps i bought just to make sure i didnt buy an odd ball hps bulb

4u2smoke the ballast does say on the side of it Lamp type M59 and my HPS box says on it ballast info and for a 400 watt it is a S51 so im pretty sure those are the same thing and it is not compatible which kinda sucks i was hoping to save some money and not buy a hood and just use this which i already had but oh well guess i will have to veg for another week while i wait on a hood to come in the mail

this might be a stupid question but is a ballast necessary?

4U got ya Mighty luck yur trail friend yual in good hand

[ShOrTbUs]

ohh yes a ballast is 100% needed

 

[DarkHorse007]

thanks figured you need a ballast to support a larger bulb without tripping the breaker i just wish that i could make this one work because i dont have the time or money to get a new one

If that light fires the MH, then it is a MH fixture. I have never seen a high bay fixture that you could interchange the type of bulbs between MH and HPS. If you want to run a HPS in this type of fixture, you are going to need an HPS conversion bulb. In addition, it is going to have to be the same wattage.

I have never really had much luck using those type of light fixtures--they are hard to cool and the light spread is poor with the type of "reflector" they have. Many moons ago someone wrote a DIY on separating the ballast from the rest of the works and making it more like a grow light than a warehouse/stadium light. I'll see if I can find it.

 

[4u2sm0ke]

you can still flower with that...I would maybe throw in a couple red cfls...and if the temps get too hot..you can allways take that light apart and be able to have the Ballast(where heat comes from) on outside of grow( called remote ballast).....ya know home depot sells the 250 HPS fixtures...even one those in with your light would be banging IMO...

take care and be safe

I looked for that thread as well for Backwoodsdrifter...If Im correct mojavemama did this...I made a few in the past and if need be Ill make another for the site...I think the thread Im thinking of got lost in the crash:cry:

hope this helps

thanks guys all the help is much appreciated ive got a little work to do lol

backwoodsdrifter i went and checked out your setup again and was wondering what will you do to flower, will you switch over to a different hps setup or do you just stay with the same lights and go to a 12/12 schedule?

Yeah, Like BWD said, you can flower your plants just fine with the MH fixture you have. It seems to me that the HPS does a better job in the end, but until you get the cash to do different, that light will suffice.

But like Smoke and THG said, you have to make sure you get the plants situated to get the best use of the light(or cut away the reflective cone and make your own reflector from mylar covered panels), and you have to make sure you have good ventilation so that you remove the heat buildup from the light and ballast.

If you have any mechanical and electrical knowledge and ability, you would be best served to take the light apart and remove the hood, and separate the light socket from the ballast. That way you can connect a longer power cord from the existing wires in the ballast, to the light socket which will allow you to hang the light pretty much any way you want, and have the ballast outside the grow-space so that you can keep the excess heat from the ballast from building up in the grow-space.

I use Reflectix in my cabinets as it has mylar and lots of dimples to break up the hot spots. Its the same stuff from which they make the car dash covers that you put in the windshield to keep the sun from cooking the inside of the car. You can get it in2', 3' and 4' high rolls and make any kind of shaped hood you want by stapling it to a wood frame.
