HPS VS. MH

[llamaman666]

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.

show me a link! I disagree with this, I find no difference in potency whatsoever with the two, just yield

The Cannabis Grow Bible by Greg Green:

All strains vary in THC levels and quanities or pecentages. The difference between THC levels and THC quanities is that THC levels are genetically determined: they cannot be influenced by the grower. THC quanities, on the other hand, are related to bud mass and how much resin can be collected from that bud mass. By way of example: some bud may only contain 20 percent THC, with a THC level of 5. The same plant grown under better conditions could produce 70 percent THC, with a THC level of 5. The level is genetic. The quanities 20 percent and 70 percent are under the grower's control.

I know for a fact that metal halides are designed mainly to encourage leaf and stem growth. High pressured sodiums are designed to promote flowering. With that being said, high pressured sodiums will encourage your plant to produce more resin (trichomes), and peak your plant's potency to it's maximum. But, if KanMan was correct, then my theory for his statement would be that the mh produces a higher THC quanity, but the hps helps the plant achieve it's maximum THC level. Fact is, that in reality, an hps improves yeildage, helps cannabis produce more resin (trichomes), and helps the plant to achieve it's maximum THC level, better than an mh.

You are welcome to go along with the standard thought that HPS is the way to go.
SanClem stated the case for halides over and over and over to you all; ie; that halide has more USEABLE light for the plants. I have confirmed SanClems assertions by using both types side by side. "Flowers" are NOT what you are trying to grow, BUDS are! Flowers are NOT buds! Buds are VEGATIVE growth.
THC amount is product of genetics, not the type of light used.

use both. it doesnt hurt a thing.

I think you meant THC level is a factor of genetics. THC level and percentage are two different things.

Howdy MajorBuds,

I would like to believe sanclem,because all I have at this time,is a 1kwatt mh. It seems that I should add some hps during flowering..the question I have-is how many watts of hps,would make a difference..when run side by side with a 1kwatt mh ?

Have a good one...

Try 1000W Halide with 400 sodium. You'll see the bud difference in yield, taste,buzz favoring the plants nearest the halide.
SanClem is a guru. His main point is that halides have more USABLE light for plants and that they grow more weight and much tighter buds. He has MUCH data from his own tests to prove it. Ever see his plants grown JUST with flourescents???(BLUE spectrum).
Halide is the way to go, much more pleasant to work under also. ALWAYS use extream caution with halides..they are VERY delicate. Use gloves when handling halides,do not put undue pressure on them. Sodiums you can almost throw against wall and it won't break.

Howdy MajorBuds,

Yup..I know sanclem from Marihemp, and I would like to see some of his grow pics..do ya reckon a search at Marihemp,will yield some ?

I have approxiamately 16 - 18 square feet,that I will be using to grow 4 plants in ,and if I divide 1000 watts by the square footage,that means that I'll have 62.5 watts per square foot,right ? If I add another 400 watts to that,it would jump up to 87.5 wpsf,isn't that too much light ? I'm worried that the 62.5,is too much..?

Yup..I wear soft,clean latex gloves,when handling the mh bulb..I didn't know that they were more fragile than hps..learn something new-every day !

Have a good one...

Hi i now have the mh and my next grow i will use. What i got was MH with a built-in ballast. I didn't realize ballast's were so heavy, plus i have to hang and adust the height. Shouldn't be a problem.

Howdy genuinestoner,

10-4 on the heavy ballasts..the one I have for my 1kwatt mh,weighs 40 pounds ! It does sit on the floor..thank goodness !

Have a good one...
