HPS LIGHT FOR VEGGING????

[smokinbuds21]

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!!!!

[SpaceNeedle]

yea that will work

[smokinbuds21]

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!

[jamstigator]

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.

[stinkyattic]

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.

[psteve]

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.

[twoguysupnorth]

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.

[HippyInIreland]

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:

[smokinbuds21]

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

[smokinbuds21]

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

[HippyInIreland]

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:

[bongerstonerd00d]

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.

[psteve]

b0ngerExcept that 6500k bulbs are 'daylight' not 'cool white' (cool white are generally around 5000K)

[highallthetime]

The HPS will stretch the plants and make them grow fast and tall , Metal Halide will make them grow slower and bushier.

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.

I said "cool 6500K", NOT Cool White 6500K. Tryin to split hairs with me or what ?


Color temperature is a quantitative measure. The higher the number in kelvin, the â??coolerâ?�, i.e., bluer, the shade.

Cool White 4000 kelvin
Daylight >5000 Kelvin

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.
I go by what's on the bulb's packaging.
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.

You nerds.... lol.
I love you guys!

[HippyInIreland]

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:

[smokinbuds21]

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!!!!

[smokinbuds21]

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?

[psteve]

No, you can get a conversion bulb, I don't think they make one in 50 watt though.

[smokinbuds21]

PSTEVE

whats your opinion on using hps and fluro's together for vegging and flowering i have read on diffrent grow guides you can use hps for both fases and will still work

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!!!??????????

[bejay]

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.

[jamstigator]

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.

[psteve]

But if all you have is an HPS light, and you can't afford ten bucks for some cool CFLs,...Then good luck paying your electric bill!

[smokinbuds21]

nobodys been really reading what ive been saying then because im not trying to choose between hps and cool white fluro's im using both!!!!!!

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!!!!!!!!!!!

[romdog11]

i dont know if anyone has said this but he has way to few lumens. i grew a crop with 250 watt lights one mh for the veg and one hps for the flowering and the flowers were way too fluffy. I recommend he takes the hps light back and invest in some real grow equipment so he is happy with the results. thats just me.

[Suspectelite]

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.

[smokinbuds21]

?????? p steve doesnt make any scence

[smokinbuds21]

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!!!

[smokinbuds21]

why is a mv light used for flowering wouldnt you use that for vegging if any???

what does it do to benifit the actual plant it self??

please inlighten me!

(except when you say 'warm kalvin'. The word is Kelvin, and what you want are 'warm white', or low kelvin rated bulbs.)


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!!!Of course they are. When did I say they weren't?
I was questioning romdog11's confusing and incorrect post which wrongly stated that you should return the HPS in favor of 'real grow equipment'.

[romdog11]

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.

[smokinbuds21]

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 likely
coming from a commercail grower just like trying to use mv bulbs just way to hot you just cant but all in all you make sence not with the grow equipment butt the hps 400 - 600 you do!!!!

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.
just a thought!

[smokinbuds21]

i could but dont want to redu all exuast fans!!!!!!!!!!!!!

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"

[stinkyattic]

The day I see a successful HID grow in a rubbermaid tote.... WOW. That would be pretty sweet. Good luck on that....

[psteve]

HID grow in a rubbermaid tote....

no hid's way to hot for me!

[stinkyattic]

tee hee... I appreciate that you saw the sarcasm in that pee "are we STILL arguing? WTF!" steve... :D
yeah that's what I'm laying down. CFL=microgrow. HID=space to do your thing.

[smokinbuds21]

EXACKLY

[Suspectelite]

what does it do to benifit the actual plant it self??

please inlighten me!
apparantly uvb ray aid in the production of more resin glands, is that not benificial?

[orangeman]

Check my log, I did the whole grow with a 250 watt HPS from seed to harvest. I hear it's not as efficient as a light with more of a blue spectrum to it but nevertheless it still works.

[Opie Yutts]

You can use ANYTHING for veg, but of course we all prefer metal halide. Pretty much any kind of light will make the plants grow. However for best results use both spectrums of light for both veg and bloom. Something like 80% blue and 20 red for veg, and the opposite for bloom.

However you MUST use a red spectrum during bloom or you will be very dissapointed. You can use one HPS bulb or many fluorescents. If you use fluoros, you will need the good expensive ones from the hydro shops, not the ones from a hardware store.

[smokinbuds21]

yes you can use the ones at the hardware store you just have to get the ones that are warm white!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !

and yes i new i could youse both light's for both makes sence but now im just using fluro's for vegging and will be using hps and warm fluro's for the flowering!!!!!!!!!

orenge man where is your log theres no link would like to check it out!!!

[bl4mm0]

I'm 2-3 months into my first hydro grow. I use one 400 watt HPS for veg in a 4X4X8 box and it worked fine for 4 plants. I'm 5 weeks into bloom now and the buds are puffing up nicely.

Heat is the main problem I faced. You definitely want to vent the heat through a tube light if you are going to go with higher wattage.

[psteve]

Once again, I will step in here and clear up a couple misconceptions.
Misconception #1 "If you use fluorescents for flower, you must use the expensive 'red' grow bulbs from the hydro store"...
Bullshit. You can grow just as well using compact fluorescent bulbs from MallWart or Home DePot.
Misconception #1-a "You must use warm white bulbs for flowering in a CFL grow".
Not necessarily. Your plant prefers a particular spectrum of light, but many combinations of colors from within that spectrum will make your plant grow. Ideally, you want as many colors as possible represented in your bulb choice. This is why so many of us use HPS, fluorescents, and MH together during flower.
So, if spectrum was the only consideration, you would want several bulbs of each color temperature (warm white, soft white, cool white, and daylight).
But spectrum isn't the only consideration. MUCH more important, is 'LUX'.
I won't bore you with math, but basically, LUX measures the intensity of lumens.
CFL's are low lux.
If you are using CFL's, you are already compromising many things. In the compromise between lux and spectrum, your plant will much prefer getting more lumens over more red in the spectrum it receives.
The CFL's that give the most LUX, are daylight bulbs.
The CFL's that give the widest spectrum, are daylight bulbs.
The CFL's that give the least LUX, are the expensive ones from the grow store.

If I was going to flower with less than 300W (actual) of CFL's, I would use daylight bulbs all the way through.
I would use as many as possible (ie. more lower wattage bulbs, vs. less higher wattage bulbs), and I would keep them as close to the plant as possible.
If I was using more than 300W, I might start thinking about adding one or two warm white bulbs.

[ismokealldaylong420]

well my friend is using a 400 watt hps for vegging 10 black dominas right now and there bushy as ive ever seen that strain so yes you can veg with hps go to hightimes they have some good answers also and all those people are pros at growing gardens indoor and outdoor that were i got my info for a small outdoor garden i did year or two ago i should mention the space he is using is 8 square feet and 6 foot tall and his plants like i said are good and growing viguoresly ill try and putt up some pics if he doesnt mind

[psteve]

400w is ideal for that space. And again, the plant cares more about light levels than about spectrum.
If you vent your hoods, and put your light close enough to the plants, HPS can veg just as well as MH or fluorescent.

[smokinbuds21]

thankyou this is why i started this thread is so i can hear everyone opinion on hps for vegging

and i guess using daylight bulbs should be better in flowering then warm bulbs i could also use both justa make sure

my box does have great airflow for its size!!! so heat will not be an issue my box dont even see past 80 degreese and at night it goes to atleast 60! its 78 in the day and 65 at night to be exact

[smokinbuds21]

really dosent matter what light i use now its all fucking useless

well just ran into a BIG problem where we have are grow box whitch is my friends house he cant have it there anymore hes got someone moving in has to get rid of the box should we just put these babies out side really have no choice!!! so im probley gonna just let nature take its corse!!!!!!!!! sorry and thanx for all the info i guess ill have to take up outdoor growing!!!

it kinda sucks though i think growing indoors gives better bud and safer but outdoors is fine if you know a good place!

[twoguysupnorth]

sorry about that. you cant use your own place?

[smokinbuds21]

wel i have kids 2 of them and i get to paranoid to have anything here but i have good news my friend called me and told me the person isnt moving in so that GREAT life saver!!!!

i dont like growing out side i have done one plant in the last two summers and only used fert stcks aint that some shit?

anyways two guys up north havent seen you in a while what you been up to? still have any grows going on? thats funny cause were to guys up north also!

i finally started a new grow after i got attacked by hermi's! we are doing scrog 3 plants just to see how it works and hoping for god for a female!!!!

if no females and get hermi again ill probley keep going with it ill just do sog next time!!!

[Opie Yutts]

it kinda sucks though i think growing indoors gives better bud

Not true. It's just easier to control, and get bigger buds and more resin (the good stuff). But the high will be the same on the same strain, indoors or out.

[Opie Yutts]

Once again, I will step in here and clear up a couple misconceptions.
Misconception #1 "If you use fluorescents for flower, you must use the expensive 'red' grow bulbs from the hydro store"...
Bullshit. You can grow just as well using compact fluorescent bulbs from MallWart or Home DePot.


OK, OK, you are technically right. When yield is concerned, you can get whatever yield you want (to the plant's capability) on whatever light you want, provided you use enough of them. You would need a shitload of the cheapo bulbs to equal the yield of a couple of the expensive bulbs. As far as total cost after considering electricity for both the bulbs and the ventilation required for each, I don't know for sure which is better, but I have to assume it would be the one with the fewer bulbs.

Is watts watts? Does 400 watts of the good bulbs equal 400 watts of the cheapo ones? Not sure, but I think the good ones are geared to flowering and have more of the proper light spectrums.

Not sure, not sure. I'm an HID guy, especially for flowering.

[smokinbuds21]

like i said before no hids hear to hot for me!!!!!!!!!!!!!!

yes and no if it says 100 watts or 400 watts its true they cant sell false info makes sence dont it!!!!!!

and outdoor takes to long for me!

[ismokealldaylong420]

outdoor growing is not good indoor is way easier outdoor you have to worry about people ciming by and telling on you or taking you shit and then telling on you rofl and bugs or horribale outside also so just stick to indoor growing if youve got the time and money to put into it

[smokinbuds21]

thats how i fell!

[twoguysupnorth]

hey smokinbuds, we arent doing to bad. i am getting myself ready for winter and fall. one mom i cut up and used for clones, ill flower whats left of her along with the other 3 clones i already have. im trying the perpetual thing and it looks like it could work. i am pretty happy, i just need to get some better supplies soon. ph tester, rooting hormone, just some of the basic things i havnt had any money for. and someplace to get some good cheap soil, the store i like only carries dirt seasonally and they are already out of my favorite. good luck with yours. good news about your friends place.

[twoguysupnorth]

hehe, i never caught that smokinbuds. i guess you are arent you? 2 guys up north!

[smokinbuds21]

yea well all that sounds good! we are now trying to attempt three scrog grows right now hopefully it happens great ill keep ya posted wit pics!

[blackdomina]

my brothers sisters cousins uncles grandmas neighbour knows a guy.. that has had no problems getting 1.5- 2 lbs per 1000w hps , with plants that were veged under only hps, personally .. i know mh are better for veg.. but certainly not essential, especially for sogs that only have a short veg.

Same goes for mh for flowering .. swim has seen side by side rooms .. one room 2 k mhs .. one room hps ... same strain .. with little difference in yield.

[the image reaper]

I grow with HPS from 'cradle to grave' ... :jointsmile:

[stinkyattic]

outdoor growing is not good indoor is way easier

lol I know some dudes up north who would disagree with ya. They think I'm NUTS for growing inside, while year after year after year they bring down STUNNING outdoor crops with almost no losses to wildlife, thieves, or cops. But that's with about 20 years' combined experience.

[smokinbuds21]

yea but then again you can grow inside during the winter and you control your own climate and or lighting/flowering cant do that outside!!!:thumbsup::thumbsup::stoned::stoned::hip py::rasta::rastasmoke::pimp::jointsmile:

[jamstigator]

I'd love to grow some outside plants, see if I could get some of those 18- or 20-footers that I've seen pics of. But A) no place nearby even remotely usable; B) paranoid; and C) lazy. ;)

[twoguysupnorth]

sorry smokinbuds for being ignorant but what is se goetaland? are you a diplomat from some far off place? lol.

[smokinbuds21]

nooo nooo diplomats here just love reading about everything lol

[smokinbuds21]

the personal prfoile wanted to no where i was from i put anything and thats what poped up

[Villui]

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!!!!

add a handfull of cfls for added blue spec

[smokinbuds21]

i have plunny cfl's and i also dont think the person that left the last reply didnt read the hole thread just the first page! lol
