Good to know that both HPS and MH are still very useful. LEDs get way too much praise.

[tolfan]

Thank you for posting this short and clear. I have the metal halide bulb before high pressure sodium I forgot what the color range should be.

I've vegged with the same 1000watt hps for the last 9 months and I had a crop before that from on the same bulb, personally I've always seen faster growth rates with hps and also encourages easier transitions to flowering

[TheFraternalHouse]

Well Done. Many so called 'experienced growers' can not EXPLAIN the difference between MH v HDS or when to use each one.

[myrtyltheTURTLE]

Great vid. Very clear and packed with information. Much appreciated.

Fortunately, the future is high pressure sodium, the industry standard. The golden glow renders Georgian (18th Century) and, indeed, all brick structures so beautifully.

The frost on my high sodium light is flaking off on the inside of bulb does that mean it's bad?

[Alex_Correa]

That is very interesting! Any reliable scientific source to understand more about the changes of the natural changes of sun spectrum? Thanks in advance.

Good video
Short and to-the-point
I do have a question though.
There's all kind of videos on how not to use a large HPS in a small ballast but can you use a small bulb in a large ballast:
1000w-bulb in a 600 ballast-NO...
But what about a
600w bulb to a 1000w
ballast.???

Will this light bulb fit and work inside a regular home light socket ? Or does it require a special fixture?

[kayamkulam]

Hi, I have a pot of leaf plant and I want it to survive the winter inside so can you please tell me which is the smallest metal halide I can use for that and how far it should be from the plant? Please answer.

[marknovak]

What about Son T bulbs? Allegedly developed as a dedicated grow light, but how do they compare with MH and HPS?

[jabdesigns]

QUESTION: Do the "conversion" bulbs I see advertised then accomplish the purposes of the 2 different bulbs? Do these bulbs have a way of switching from one to the other? One conversion bulb I saw said it needed a MH ballast....important? And what size watt bulbs would you recommend for a 12"x24" planter box? 100? 400? 1000? [I have only a north side exposure, so my recently transplanted small plants here in Florida are hurting from only indirect sun, and even in summer, only 2-3 direct hours.]

One way to increase output from metal halides is to break the outer glass which gives off more UV for your plants.

[coopermuccio]

What about mercury vapor bulbs? Are they useful anywhere here?

[robertlefave]

great information, high pressure sodium for buds, yes, yes, yes!

[agentvids]

what is the value of capacitor for 400W metal halide lamp?

[droopydonttrip]

I didn't know this info
Right now im vegging with a hps bulb plants are only 2 weeks old
One of my ballast has a switch that says H.P.S AND M.H and the other ballast does not can i still run a M.H bulb on my 1k ballast setup if it dosent have the M.H switch?

[williamdougie]

Doesn't matter which bulb you use to veg or flower, you have to manipulate the light schedule.

Great video right to the point great job!!
