A snippet from another site on infra red hope it helps.

The plants use red and infrared light to regulate stem growth and flowering response. Plant cells produce a chemical called a phytochrome, which has two versions. One version, PR, is sensitive to red light (660 nm). Red light converts PR into PFR. PFR signals the plant to grow short stocky stems and also helps the plant grow into specific shapes. The plants also use red and infrared light to measure uninterrupted darkness. As far as plants are concerned in terms of flowering, if there's no red light, it's dark.

PFR is sensitive to infrared light (730 nm), which converts it into PR. When PR levels build to a critical amount, scientists hypothesize that a hormone called floragen becomes active and induces the plant to flower. The reason floragen is called hypothetical is that researchers can see its effects, but they haven't found it yet.

PFR reverts to PR naturally. For PFR to be present, it must be renewed continuously by the presence of red light. When plants are shaded, they get less of the needed red light. In the absence of red light, the PR version predominates and the stem stretches to reach the light. Lower side branches shaded by leaves from above have PR and grow longer until they reach the light. Then they modify their growth in the presence of PFR.

Wow good info many thanks still confused though as it sounds like I could use it to stunt my girls growth but not shock her into protecting herself by increasing trich production.

Not just confused but more confused. Should he use it or not.

hey I did not profess to have an answer im trying to work it all out too. LOL just trying to provide a little base information. if anyone can chime in feel free im interested too.

 

[Light Addict]

Hey SWvoodoo yeah thats what I meant to get a uv bulb and got a heat one for back pain instead (infrared) lol. Just noticed the red bulb and thought yey! Would it still work though as still should anoy her and make her want to protect herself with trichs? Or am I being dumb and it would just cook her.
Many thanks carestaker your to gracious.

 

[SWvoodoo]

No ive searched heaps and cant find anything concerning benefits of IR bulbs except for heat in lizard tanks (they cant detect the red spectrum the same as MJ cant detect the green spectrum) so u want a reptile UV globe like an exoterra reptiglo. They come in different spectrums and wattages not too cheap tho and from my lil bit of research the benefits are marginal but that's just my 2c. I have some laying around from my bearded dragons but im not rushing to get em in there.
There was people quoting scientific papers about the advantages of uv on trichomes but remember all light is covered in one of the uv spectrums uv a,b and c. My head hurts lol

 

[RainStacks]

Just read your journal from the start. Very impressive training methods. You are meticulous, and clearly have a deep understanding of these beautiful plants. I am excited to see how things develop. Thank you for sharing your methods with us. I loved your BV, so I am subbed

 

[Light Addict]

Thanks SWvoodoo that is what I thought many thanks for clearing that up my friend.

Rainstacks many thanks indeed and welcome.Im loving sharing my ways and am getting great feedback. Better than id ever have guessed. Glad your on board.

Some thing I learned about PR and PfR, also from an outside source so take it with a grain of salt--- Any light during the darkness period cause the plant to revert all the PR back into PfR and the night is wasted. Thus the gas latern routine.

Good weed Sir Light Addict. Hope all is well sir.

You've deservedly acquired many fans since you started this journal. I saw that POM you grew & knew that's how I wanted to grow.
Congrats my friend & thanks for sharing your knowledge
People brand new at growing, have no idea how lucky they are that this type of info is so easily obtained nowadays.

Plants & Ultra Violet Light | eHow...dam...who did that...

 

[donpaul.p]

spimp is spot on, glr works because it gives the plants 12-12 through veg but we give an hour of light in the middle to keep it in veg, the flowering hormones build up a lot more under glr and flowers quicker and sooner when you switch to just 12-12,

with the light you got it might produce more heat than benefit the plant, i take it you was going to supliment your lights with a uv light but ended up with this ir light, from what i can remember them give off more heat than actual light so i dont think it would be of much use, even if you had it far enough away to stop the heat you might not be getting much light at all,

with the uv lighting again this can cause problems, you only really need short bursts per day and not have it on for the whole lights on period, how ever their is not much proof that uv helps increase trich production, ive dont much research and ive read both sides of the argument that plants produce trich to stop the uv damaging the plant, if this was the case then it would produce trichs in veg, the other theory is the trichs are to stop animals eating the plant and buds, so it produces trichs to make it not tasty for animals and bugs, but again no proof and most outdoor growers know that rabbits and dear eat plants in all stages of growth so im my oppinion that proves trichs are not that to make the plant taste nasty to animals else they would not keep coming back to eat the plants and we know bugs like to eat the buds so again that goes agains the trichs been their to stop it getting eaten,

now trich production is pretty much down to the strain, their is very little you can do to increase trich production, their is only 1 method that i can think of that may increase trich production, i say it may as again its not proven but this has the most truth behind it so in my oppinion i think this is the only option to increase trich production, but again if you buy a strain that dont produce much trich then you wont get much trich no matter what you do, but then if you buy something like white widow or a kush then its going to be covered in trichs no matter what you do or dont do to it,

now the only method i would say is the best to try is humidity, if you lower the humidity through the flowering process then the plant may produce more trichs, this sounds about the best method as if you look at outdoor grown plants in its natural growing places then the plants that are used for making hash come from places with high temps and low humidity, these plants produce lots and lots of trichs and its why their mainly used for making hash out of so they can then export and sell it on the black market, now in countries where humidity is higher the true landrace strains produce a lot less trich so this suggest to me that humidity plays a big part in this as uv would be about the same give or take in both environments, the only difference was humidity and i think temps but id have to check,

so their is a guide that suggests to lower the humidity 2 or 3 time during flower and this then may increase trich production,

but to be brutally honest its pretty much down to the strain, ive grown strains that produce very few trichs on the sugar leaves then ive grown strains that look white due to the amount of trichs on leaves and buds, both grown in same humidity and temps so again the only difference is the strain, if you can increase trich productio then again its going to be very slight and possibly hard to even notice even if you did a side by side grow.

so choose the right strain and im sure you will be happy with the trichs, when i get a plant that produces well i clone it and either produce fem seeds for future grows or i keep it in clone form,

if your interested in the correct humidity settings then search for strain hunters kings kush video, their it give the exact temps and humidity throughout each stage of growth, so that will give you some idea of humidity if you can control that, id have to say that i think its the only option that makes a difference, is it going to be a huge difference, well i doubt it as my humidity is pretty high during some times of the year and ive still produced plants covered in trichs and other strains with very few trichs,

the only thing i noticed that actually increased trichs on the sugar leaf is when i removed all the leaves on the plants a week or 2 before harvest, the sugar leaves then got bigger and it must of pulled the trichs out of the plant more or it must of produced more so it could coat the leaves that are having to grow to replace the leaves i removed,

Some very cool info being shared here. Very cool that one can influence how fast a plant kicks into flower. Why is this not more popular? You would think the plant had more time to flower as it uses up its stored energy. Is the benefit just minimal? Or am I wrong in my thinking?

DP, I think and Greenhouse seeds need to be paying you. You just love those strain reviews hu? Well I can't blame ya, I have watched the Chemdog one 3 times now I think.

 

[Light Addict]

Thank you all. spimp sir a pleasure as always, Cajuncelt your words are to kind my friend, many thanks. Miwa great link even led onto one about Infrared and more so thanks. Donpaul great info bombing as usual many thanks. Rainstacks great to have you popping in again and your right Im loving some of the topics on my humble little thread.

I did start a thread a while back where the humidity trick was discussed at great length. So well up on that one, but great to have it on here for new growers so thanks once more to the Don.

Sodding hell just thought I picked up a nice cheap addition of a UV lamp for little bursts during flowering. Found it in a charity shop thought yeah wicked. Get home and its Infrared. Im pretty sure this is not usable but if anyone of you guys could confirm. Its was supposed to aid in trich production.

Infra red only makes them stretch as the shaded leaves get more far-infra red than normal.

It also makes heat (duh) so don't use it

Get a T5 UV-B reptile tube or two.

I am just playing around with alternate light sources at this point. I started at this from a different angle. I was wondering why I was able to grow such good plants outdoors this year and not duplicate it indoors. I planted the same genetics outdoors and used the same basic nutrient plan. But the outdoor plants just killed my indoor ones with taste, potency, and smell. It was immediately obvious in July as they started budding that there is a major difference.

Research led me to UV-B as one of the major lighting elements missing indoors. HPS lamps generate a small amount - but if you run a vented hood with a good quality lens - it takes out 90% of the UV-A and UV-B light. You end up with essentially nothing. UV-B is deemed important for the generation of essential oils in plants... so I ran an experiment where I purchased a terrarium light (UV-B 10 bulb) and started running it on the edge of my large HPS.

It doesn't provide good coverage of the 4x4 tent - but this is perfect for my experiment. When I placed the light in the tent - the portions of the plant exposed to the light came out much more heavily coated in resin, better smell, and taste. Basically two buds off the same plant with very different levels of resin. UV-B works.

GreatLife4all uses them along with HPS and is getting close to outdoor quality, apparently

Although I think all cfls emit uv-b, that's why they shouldn't be used in table- or bedside lamps.



Has anyone ever tried a Mercury Vapour Spotlight?

Because these have a focused beam, they produce very bright light and high UVB concentrated like a patch of sunlight.

Light addict hello mate. Some interesting reading on this page just guna check back

 

[Light Addict]

OK everyone here is a little update.
As my bloody workman aint turned up for 2 weeks now, I've ended up vegging longer under CFL than I wanted too. I would have normally had her under my 400 hps by now. Also because I let her grow 2 nodes higher than normal, before topping her I've had to adjust my style slightly.
I've been tying limbs back as usual, I've been using more defol along the way. I am also now beginning to tie down some of the lesser shoots; ones that have originated from a branch.
I am still tucking leaves away especially still the two upper fans. She has so much going on with her, masses of growth sites all over her.
Soon I shall let all lower branches start to climb vertically, whilst still manipulating the higher shoots for some time.

Other news; my clone she is looking fine and dandy, so I'm well happy with that. It was my first ever go and think I did it!

My baby little Critical Sensi Star is re-potted into a bit bigger home for now. Normally I go straight from seedling pot to my big 20gal, but space is my issue for now thanks to my sodding tradesman.

Here's some pics.

A lot of reading to catch up here! Amazing to see how your plant is progressing!

+ reps

 

[Harley001]

My LEDs came with UVB

 

[Light Addict]

Cheers for the reps mono, Im glad you stopped in and caught up.Its great to have so many big names from 420 following. I feal blessed.
Harley, Ill have to save some pennies and get a reptile uv at some point soon.

 

[Mono]

Reps are well deserved for the good work you've got going on here.
