how much less would u yield flowering with a mh rather than a hps? Just wondering because i have a mh but only want to spring for a hps if i have to. If I can get decent results with a mh then I will just use that.

Right, if you have a Metal Halide bulb, you CAN flower with it, but because its the wrong spectrum you wont get as much.
Get a High Pressure Sodium Convertion bulb of the same wattage as your MH.
It'll fit into the fixture, and you dont need separate blallast.
Seriously, HPS is a much better option for flowering.
If you want a good harvest, invest.
thanks lips, do u have an idea about how much less u would yield flowering with a mh than a hps say for a 3 ft plant of bagseed?
I have no idea mate, all strains are differnt, some only geneticly yeild a cuple of grams, while others can yeild more than a pound [16 oz]
It all depends, there no way to be sure.
Sorry.
Thats alright. growing is about trial and error, so ill just flower with the mh and if the results are undesirable then ill spring for the 400 watt hps. thanks for the help.
No probs mate. Keep us updated. Put it this way, you'll get a yeild, and you'll get something nice to smoke, just HPS will give a higher yeild. It's all about the light spectrums.
MH [White/Blue] Veg
HPS [Red/Orange] Flower
Father and law does the whole grow with a MH and gets about a QP per plant. Some old school growers use it threw the whole grow all the time. I got 2 1k MH balasts from a guy that had about a 6K set up and all he used was MH for years, about the last 15 years. I would recommend a HPS, but I am just giving examples of people who still go that rout the whole grow. Give us the results.
Adieu
why not get that conversion hps bulb for 50 bucks?
When it comes to difference between MH and HPS for flowering, from what I have read/understand at least, It would be worthwhile to get the conversion bulb.
i have used my 1000 watt mh for flower and you lose about 1/4 of the yeild . depending on the strain. i can only say with white widow as i grew both once with 1000 watt mh and many with 1000 watt hps.some poeple use mh when they have hight restrictoins as flowering with mh keeps the plants small and the buds tight and more compact than hps but looses in weight. hps is the correct spectrum for flower and yeilds more
I grew 3 plants of reclining buddha about 4 years ago with 3 MH bulbs and fixtures,each 250 watt. I got about 1 oz of each plant . Trial and error like u said my man , good luck
There was a post recently where someone was asking why he had only tiny buds after nine weeks, it was because he was using MH instead of HPS.
If you can... the ideal thing to do is go from MH to HPS
but don't take my word for it..
I have looked and looked for a conversion bulb that is hps but made for mh ballasts but all i can find is the exact opposite. If anyone knows where to get one plz spread the knowledge.
You can also try a red burning mh bulb but they are 3000k and the hps are 2700 hundo, I don't see how 300 degrees kelvin will make a difference.
HPS in veg increases the chances of a higher male ratio.
..that would be best!.....second best? 400HPS Hortilux...would be my choice.Quote:

I did a quick search and this was the very first result: http://www.gchydro.com/EYE+Hortilux+...ast+-+HPS.html .
I didn't do any further searching since it's obvious there's plenty of this info available at your fingertips if you step away from the bong for a moment and look for it. :stoned: With a bit of research you can probably find one for $50 - 70.
what about using a red/orange peice of plexiglass between the bulbls and the plants?
Am I the only one who uses MH and HPS together throughout veg and flower??? Dual spectrum rocks - the plants seem to love it.
i use a 1000 watt mh for veg along with some cool white flouros then change to hps for flower this is the best way to go as they need both spectrums through their life cycle. but you have to use what you have if you are short on cash.be safe the postman.
How much would it speed growth for 6 plants already under a 400W MH to add a 400W HPS? Would it even come close to doubling?
Does anyone know if this will work?Quote:
