my lamp jus blew out. Its only a couple weeks old i cant understand why. I am dying. I wont get another one until nex week. I do however hav a 175w hps mercury lamp. Can it work in the 400w hps ballast?? At least until nex week. Without damaging the ballast? I giv zero fucks if this 175 blows out sometime next week. HELP

Rush order a ViparSpectra 450w for $149. 300w for $99.
Ok will do. But im outside the US so ill still have to wait a couple days. Will the 175 work for now?

It should, as long as your ballast is adjustable? I believe?

I'm not sure. @Resinhound?

Not sure but I doubt it, mercury lamps are a totally different tech besides just the obvious wattage differences.
Wouldn't risk it.

Not necessarily. I've read plants can only absorb so much light at a time and it's all to due with PAR values and Lumens, not necessarily wattage and how close your lights are. While your lights can provide higher PAR Values and Lumens by being closer to your plant the difference may be negligible if the coverage of the PAR/Lumens is sufficient, regardless of your height.
It's anecdotal but I run a 250W HPS in a 2x2x5 and my plant shows the same growth and vigor whether my light is close to my plant or resting in the top. I'm assuming I've gotten an over powered light for my space so it provides the max amount of light energy regardless of how close it is to my plant in such a tiny space.
The hps fixture i hav is also for mercury lamps cuz the original lamp for the set up is a ceramic metal halide. I tried it and its working so far.
Interesting cuz im experiencing the same thing. Actually, the buds further away from the light got more trichomes and the hairs are maturing faster and getting bigger than the buds closer to the light.

Don't use a lower wattage bulb in your higher wattage ballast even if it is adjustable.

Cyrus is the one you want to talk to. Personally, I only run LEDs. Sorry if I'd wasted your time.

Oh no I'm not the one to talk to I just know higher power supplies will blow out lower rated bulbs. I asked the same question on here and several told me to do it if I wanted to see a bulb explode/short.

One of the reasons I don't keep HIDs is, I'm accident prone, and they are fire hazards.
But i need some kina light til i get a lamp. I dont care if it blows out ill jus buy another one. But the original bulb for fixture wont get to my country til tuesday. I hav a 4.5 x 4.5 scrog net and my plant is into the 5th week of flower. I NEED light NOW. If the bulb is the only thing that wud blow then fuck it. The 175w sells here and its cheap enough. But the 400w cmh i cant get here so i had to order it.

Is there a Home Improvement store near you that sells high-wattage CFLs or T5 lights they will do just fine in a pinch and you won't have to run the risk of blowing your bulb.
If you're in a scrog net then you are in luck because you could just get the equivalent wattage of CFLs for cheap and hang them right above the plant.
