HPS VS. MH

[genuinestoner]

Hello, thought i would start a new thread with a question? Is (MH) absolutely necessary for flowering? I read that HPS will do the same as (MH)
And if i purchased a MH bulb at the depot and put it in the hps ballast will it work? I don't want to buy it if it doesn't work, or will i have to buy the ballast "just" for MH.
Thanks for any advice from anyone.

The only time to use an MH lamp is during the vegetative stage. An HPS is better suited for the flowering stage because it contains the right kelvin temperature for when a cannabis plant is flowering, making the all important THC. If you were to to buy an MH/HPS conversion lamp, then you could use both a regular MH or HPS bulb. But if not, putting a regular MH into an HPS lamp wouldn't work, unless it was an MH-conversion bulb made to work in an HPS lamp.

hi genuinestoner,if your gonna only use one lamp use the hps,you can veg with no prob's at all,happy growing..spliffbuilder.

Using an Mh for veg stage would help your moms produce more leaf mass to cut more clones. I believe that hps is the best

HPS=Fluffy flowers and buds that dry too quickly and crumble to dust when dried.

Metal Halide=COMPACT flowering and buds,better tasting product. More weight yield.

TRY IT YOURSELF AND SEE.

Howdy MajorBuds,

I'm gonna do just that,I have a 1kwatt mh,that I will be using from start to finish..I've been worried that I need to add some red spectrum during flowering..I hope that what you say-is true !

Have a good one !

backwards? yea
MH is for veging, and makes you get cotton candy buds the size of popcorn. HPS=BIG DENSE buds
oh, and with some strains it don't matter, youll always get fairly fluffy shit, like with pure sativas

Either MH or HPS can be used from start to finish.
MH produces less yield (flowering cycle) and more thrichomes when compared to a HPS.
