i just went out and bought a 50 watt hps light and fixture im gonna get another but my question is can i use a hps light for vegging and flowering i konw i can use for flowering just not vegging
i also wanted to know if you can use a mercury vapor bulb/fixture for vegging
please if i can would love two add it to the grow area!!!!
yea that will work
hold on so are you saying that yes i can use hps for vegging or a mercury vapor for vegging witch one? or both?
confused!
I'd get rid of the MV light - doesn't do much for the plants, generates much heat. You *can* veg with HPS lights, but your plants may be kinda straggly. What I'd do is get some cool CFLs and use those for vegging, or use those *and* the HPS for vegging then swap the cools for warms when flowering.
Lose the Mercury Vapor. It's all wrong for cannabis.
Cool white tube flouros or CFLs will give you the blue light that cannabis wants during veg.
HPS isn't the most efficient use of electricity until you get to flower, when the plant wants that nice red light.
I once had to use HPS for the last three weeks of a veg cycle. They were already doing well, but it didn't seem to hurt anything.
same here, ive done it but they did seem streatched out and sorta bare at the bottom. it was my first time indoor so i have nothing to compare it too. 150hps all the way through, except for some florescents to start with.
I used 2 use a hps for vegging and flowering for ages, a few grows any way .It Did the job perfect but was costing me more than i needed to you could just buy a mh buld and switch it with the hps its still going to cost the same thou .
I got two of these 100w energy saving cfls from ebay cost me under 10 pounds each they are perfect and saves me loads and they are great for vegging i luv em:jointsmile:
im only using 50 watt hps light and a 2 100 watt fluro's at the same time im not using a mv bulb at all never bought one bought the hps
so im just gonna use cool white cfl's and 50 watt hps for vegging for about 3 weeks and then going to switch over to warm kalvin cfl's and still use 50 watt hps for flowering only been in there for one day and already seeing good growth on the clones got the seedlings sitting under fluro's only 2 100 watt's and as they get bigger will move them to the hps and fluro's as well!!
so what do you think this should work pritty good im using less fluro's butt that one bulb is almost 4000 lumens and im sittin at 78 deg and fan is on medium as they get bigger i will turn on more fluro's and fan higher
the only reason why i wanted to add this is i seen a video tape on how to grow they were growing k2 and using 600 watt hps 3 of them and for vegging and flowering and came out to be real good chronick!!!
but always love suggestions and tips
IF YOU DONT MIND THE ELECTRIC BILL HPS WILL VEGG YOUR PLANTS AS GOOD AS ANY THING ELSE THE ONLY REASON I SWITCHED WAS TO SAVE ELECTRIC THEY,LL BE SWEET
THEM 2 LIGHTS THAT U ARE USING WILL BE PERFECT:rastasmoke:
Hippy, not trying to start an argument, but saying to use H.P.S. is as good as anthing else for veg is not true. WIll it work ? Yes, it will. Is it optimal ? No, its not, and far from it. Its the wrong spectrum that your plants need and use during the vegatative stage.
First of all its a known fact more "bluelight" will produce more females, along with lower temps, etc etc etc. Hence folks use M.H. or cool (6500K) flouros to veg with. Also, H.P.S. will cause the plants to stretch, not bush out. Again, not optimal.
Folks wanting to learn might as well learn the right way, then if they choose to experiment from there, so be it. You can verify what I typed above in any cannibas book you can get your hands on, by the way.

Sorry, but this is simply NOT true.Quote:

If you can afford to buy 2 sets of light to veg and to bloom do it , if not just get the HPS and work with it , because it will bud better than Metal halide.
:hippy:
I said "cool 6500K", NOT Cool White 6500K. Tryin to split hairs with me or what ?Quote:

Therefore 6500 Kelvin is "cool/blue".

Tryin to bust my fucking nuts or what, PS ? Stinkyattic called them "cool" also and I noticed you didnt bust her ass. Am I just special or what ?

Don't get your undies in a bundle just because I clarified a detail in your post. Of course daylight bulbs are 'cooler' than 'cool white' bulbs.Quote:

If you go to a store and ask for a 'cool white' bulb, they will give you something around 4000-5000k.
If you want the 6000+K bulbs, you want 'daylight' bulbs.
No nut, ass, or hair busting intended.
Are you 'busting nuts' here?Quote:

I love you guys!
Yip i knew a hps buld is not best i told him just to buy a mh bulb and switch for flower/vegg or a few clfs for vegging just if not the HPS will work as good as any cfl im not a fan of them really
Im wasent trying to change the rules ppl:rastasmoke:
you guys need to chill!!!!!!!
im using 100 watt cfl's 2 of them and will be using 4 when i go into flowering i also have a 50 watt hps light witch really is half 4000 lumens hps and i have 4000 of fluro's when flowering comes il take away all 4000 of the cool white and replace with 6000 lumens of warm kalvin bulbs
note: i only veg for 3 weeks and let the flowering do the rest!!!
all in all i think this plan really should work its got all the blue it wants and red i guess the plant takes what it wants when it wants of light that but do you really think it will fuck up my clones and or make plants hermi's or males with my light set up like this?
a couple are reacting good to it and a couple hasnt done anything yet but ive only had it on for 3 days now reply please what should i do!!!!
i have one last question i have a 50 watt hps and ballast can i just replace bulbs with a 50 watt metal halide without burning my ballast or the bulb? will it work?
No, you can get a conversion bulb, I don't think they make one in 50 watt though.Quote:

so i dont see why my plants shouldnt be ok with these lighting conditions 4000 lumens of hps for flowering and vegging and 6-7000 lumens of fluro's i do see my clones growing good but my seedling is a little yellowish tent i dont know why and the seeds i planted are taking forever to pop up!!!??????????
man this thread is way to long just veg your plants under what youve got its fine, in fact would guess that alot of growers use a hps for veg without a problem. and I would think atleast a couple of people that posted in this thread should have enough growing experience to know it works fine rather than telling new growers that they gotta have a mh or use flouros when they dont, your 100 watts of cfl will cost more to run than your 50 watt hps.
I don't think anyone has said you HAVE to use fluoros or MH for veg, just that plants prefer blue light during veg and getting the primarily red spectrum of an HPS light during veg therefor results in more straggly-looking plants, with longer internode spacing and less bushiness. Doesn't mean it doesn't work; it's just not optimal for the plants. But if all you have is an HPS light, and you can't afford ten bucks for some cool CFLs, well then, can't argue with that.
...Then good luck paying your electric bill!Quote:

the plants are growing ok!!!!!
i have read enough to no that a hps is ok just would like to hear people tips and stories thats all i have 5 ten dollar bulbs and a hps light
i read that you can use a metal halide bulb and hps bulb together for vegging and flowering i read this in a growing guide so there for im using fluro's and hps for vegging and hps and warm kalvin flro's for flowering!!!
thanx for everyone help!!!!!!!!!!!
Jams, they are called DAYLIGHT not "cool"........LOL :rasta: Look a few posts back and you'll get mah joke. Peace bro.........Quote:

yo, MV bulbs are not useless, they can be introduced, midway through flowering as a good source of UV light, I may be new, but I do have knowledge to offer if you want it or not is up to you.
Peace.

well ive dessided to take out the hps light i am only using st8 cool white fluro's i added 6 100 watt 2600 lumens each that should be enough for my setup im not growing to many but enough!
when flowering does come up im gonna buy an additional 200 watt hps light added with my 50 watt hps and gonna add 4 100 watt warm kalvin bulbs and i think my grow room is now complete we just added a 4 inch fan with duck blowing all heat out with fan blowing freash air in always 79 80 and at night 69 70 so everythings all good for now
trust me PSTEVE mh and hps lights are real grow equipment i could argue the point but no worth it thanx for everybody's help on this so far!!!
why is a mv light used for flowering wouldnt you use that for vegging if any???Quote:

Now you're making some sense. (except when you say 'warm kalvin'. The word is Kelvin, and what you want are 'warm white', or low kelvin rated bulbs.)Quote:

I was questioning romdog11's confusing and incorrect post which wrongly stated that you should return the HPS in favor of 'real grow equipment'.
i say you buy a 400 watt hps no less but that is just me. on jorge cervantes's grow guide dvd he recommends a 400 or 600 watt light and i agree cause ive tried lower. sorry if i was wrong or incorrect but all i was saying was get a brighter light, more light is always better.
romdog11 all that stuff you say i also true!!! but if your only using a 32 gallon rubbermaid grow you cant just put 400 watts of hps in there your plants will fry like an egg if i had more space i would go for the gusto and get a 1000 watter but lovin the rubbermaid grows for now snd when your reading a grow guide its most likelyQuote:

sorry steve i ment rem dog and yes your also right about the "kelvin bulbs" or simply warm white thank you p steve
i should start a new thread but im a just continue on this thread with pics
you can use a 400 in a small space like that, all you have to do is overkill the exhaust.Quote:

and i deff think 4 warm white "100 watt" cfl with 250 watts of hps with flowering
and for now just using 6 100 watt 2600 lumen cool white "veg that is"
