Things to Know About Lighting

[ganjagoddess]

Many people throw in UV-B lights in addition to hps lighting once the plant goes into flowering.

That is also why they came out with HPS with more intense UV-B spectrums.

Personally I dont think it is super needed unless your going for the cup.

If your super paranoid just spend $100 for the light bulb with the added UV-B

But also remeber only UV-B is good uva and uvc are BAD!!!

dude just get a 400w hps and a mh conversion bulb best of both worlds. anyone know anything about lps lighting?

when do i put the lights on full on plants that have just got there first leves thay are in a propagator and i have had to take the seed shell off i dont no when to take the lid off the prop and give them 24 hours of flouro stips i have done
plants before but done them from full cuttings

Dude! Thank you so much for this! I'm trying my first grow soon and this information is perfect for me! Thanks a lot, ++Rep

Hi all-

First post, did a lot of reading and have a few questions. My buddy and I built a nice grow box that has inside dimensions of 3'1 high, 1'6 deep and 2'4 wide. It contains 1" reflective insulation and weather tight with a door a fan that brings in fresh air and an exhaust that takes air out into a HVAC duct with fabric softner to help dull the smell. I will be using the Aerogarden Deluxe. I am still to get extra lights, and an air pump with airstone. This will be my first grow and I want to do this right. My first question is Lights

I have a 160W Wonderlite is a wide spectrum light designed for orchids and other tropical plants that tend to perform poorly in standard home or office environments, Its unique spectral distribution has an excellent balance of blue, red and far-red wavelengths in the visible light spectrum (440, 660 and 740 nanometers)
---Is this a good light to use?
---And will I need other lights?

If I do need another light, I would prefer to get 2 of the same to put on both sides. I dont want to use lights that produce heat to the point of burning the plants...
---Is it better to have a HPS bulb or a full spectrum CFL?
---At which wattage would I need?
---Which are good brads to pick up at a home depot or so.

I have plenty other question but I am tkaing this one step at a time thanks

Yup yup...I'm a general contractor...they are in fact all over large construction sites.

HOWEVER I HIGHLY DISCOURAGE STEALING FROM CONSTRUCTION SITES...IT'S DARK, THERE'S NO ONE AROUND...THEIVES THAT ARE CAUGHT ARE GENERALLY DEALT WITH SEVERLY WHEN CAUGHT IN DARK PLACES WITH NO WITNESSES.

BESIDES IT'S JUST FAWKING WRONG TO STEAL AND ALMOST AS WRONG TO CONDONE OR SUGGEST IT. BAD FORM MY FRIEND, BAD FORM!!!!!!

and on a more personal note...thanks, it's people like you that cost me hundreds of thousands of dollars a year replacing crap I find stolen, you know we can't work when you steal our stuff?!!?!?! Oh and those lights, that's called EGRESS LIGHTING, it's sole purpose is so we don't trip and kill ourselves at 5am when the fawking sun isn't even up yet. And when it's not in place OSHA comes and shuts down our job site because we are then in violation of federally mandated construction safety laws!!! Makes me sick when I have to be woken up by my Foreman because someone stole from our job site!!!!

YOU WANNA GROW POT FINE...DON'T STEAL FROM HARDWORKING PEOPLE TO DO IT!!!!!!!!!!!!!!

BCENVY, sometimes i like to "relax" and go on here cause i'm REAL interested in joining the club. lol You took the words right out of my FAWKING mouth when you replied. I'm not a contractor but when i was about 15 I had a mentor that took me to his buildings when he was getting them ready for new tennets, and he hated when people stole his sh!t. lol and if the lighting wasnt right and i hurt myself, he would've got his ass in deep sh!t if i would've gotten hurt. But are those lights really expensive? I got a concert to goto tonight, but Imma check on that shit when i get back.

Thanks for the awesome info! You all just saved me hours of running around!

I believe a wobble MH light goes for around $200 wholesale.

the above Graph

im kinda thick when it comes too this tech stuff. can someone explain too me if this graph for a fluro tube is good for flowering or vegetive growth.

please and thank you.

sorry if this is a realy dumb question, but i realy need help. the tubbes i buy dont have rates, they just have this graph and i dont undertand it one bit. these lighst are too add sidelighting in a flowercab

[drynroasty]

I believe that that spectum analysis shows the red wavelengths being higher than the blue, resulting in more vigorous flower/bloom than veg.

I think that is how it works. Take some time and read these threads man, I think all our answers are already posted somewhere.

 

[drynroasty]

Also, I believe the usable range of light is between 400-700, and that bulb is within.

Lol just to chuck a spanner in to the works about light (don’t get me wrong im as dumb as homer simpson) but I watch on tv men of since struggling to explain light you have 1 group saying that light is a wave form and others saying no it is in a practical form so they agree to disagree and call it a wave practical form,
Lets all have a big spliff and think about it all LIGHT HAS NO COLOR I just had a spliff and realised that light also doesn’t move far it just passes the energy to the next electron it is the energy that moves,the color is emitted then the chain of electrons strike the surface of different electrons the collision for a fraction of a sec changes the frequency of the stactc electrons. this thermal scale every one kees seeing it as not light but it is that’s why it is used it tells u the frequency of the excited electrons in the steel the only thing is that the light is traped (as heat) in the steel (if u put it in a vacume the light would escape quicker like in a light bulb) all this about 1 light for this and 1 light for that don’t u get it it iss all the same just different frequencies ie 2700k and that the frequency can be changed in more ways than a pot head like me IE WHIT LIGHT IS WHITE NO WE ONLY SEE WHITE IF IT IS SHINED ON TO WHITE IF SHINE IT ON SOME THING ELSE THAT IS BLUE IT SHINES BLUE,PUT T THIN PICE OF READ PLASTIC OVER A WHITE LIGHT AND WHAT LIGHT IS EMMITED ??
MY THINKING IS GET GOOD WHITE LIGHT AND SURROUND THE WALLS IN THE RED REFLETIVE RAPPING PAPER SO THE LIGHT BOUNCED BACK WILL HAVE RED IN IT ,AND IN THE GREEN ROOM MAKE IT A BLUE ROOM IM SHORE IV SEEN THE WAPPING PAPER IN REFLETIVE RED AND BLUE AND SILVER,
Just a quick add on leds are the way to go they have just got to get the right frequencies
Don’t forget big business will do things the expensive way to get more cash from u im wondering if the cheap nasty leds would be better as u will have a wider band of frequencies
light is a electron but what frequency it is vibrating depends on what it will do to its surroundings gamma and x-rays ect all light but on the frequency that can damage living matter (I here some one who hasn’t had enough splifs thinking light must have colour look at rainbows or prisms but as the electrons are passing though glass or water the collision is at a different angle and will change the frequency.
One more dimension if u put a small plastic sheaf over the elment in a light bulb what would it do(so long as the power wasn’t to high) nothing the electrons would carry on round the cable till it got used if u stripped all the plastic from all your cables in ur home and turn on power all the electrons will excape from the wire all the cables would go like fuse wire or light bulb element ,your pc is powered by light excited light electrons running through ur processor wanting to get out but has to go throught a maze some get to escape as heat.
That’s my little stone head rant and I cant even spell so im not trying to look clever (did this in word to sort spelling a bit)

homer simpson.. red walls would be bad. when light hits a colored surface, every color of light is absorbed "except" the color of the surface, which is reflected. red walls would only reflect red light, all other colors would be absorbed. this is a bad thing because we want more light to reflect back to the plants.

thought the idear was to increas the red u have main light in plant the reflected light will be the extra red u want for flowering it will only reflect what missed the plant first time round

here is some thing else i see program years a go where they noticed pine trees growing 1rd quicker then the rest turnd out was the overhead power cables giveing off electromagnettic radeation (getting my plants in cella this week i want to rap a ext lead cable round the pot of pne and see if there is a difference)might be why 1 light works better tan others is the emf from the large ballist
just a smokeing thought

while I agree that more red light could only help the plant, adding red walls to a room wouldn't really add more red light, but only seem that way. the walls would reflect red light and absorb all the rest, while walls painted flat white will reflect the same red light with the addition of all other colors. you're not really adding red light, but removing other light that would otherwise be reflected. A for affort!

interesting. you wouldn't happen to have the article, would you? sounds like a strange phenomenon.

 

[sinsemilla666]

hahaha dude steeling lights and using them to grow bud is bad karma.. go buy some they're not that $$$ I got mine used for $150. thats with a brand new bulb.

just kiding dude i would hardly steal some light ballast from someone, i just got mine from ebay and i love it, cheap and realy works.

no sorry cant remember what the program was about,but they did show u the rows of pine trees under the power cables and u could see they were a 3rd taller and thicker branches, following the lines of over head power cables.also can cause cancers to us so dont have a to big emf ner ur plants (when i get my plants in cella this week i will try and take reg pic of it and others in cella and compair,only got my new cuttings down thwere right now today is there 2nd day lol i might be a dady again soon

my babys for cella will take pic of my cuttings if they take and follow there progress iv got a few leds on cables for cars i want to put over 1 cutting and see if there is a difference to others,

put a bunch of cell phones around your plants to give them a little electro magnetic radiation. I've heard of power lines causing stronger paranormal activity. the last thing you want is cancer and haunted plants.
