flouro reptile lights with UVB.

i bought two 40watt flouroescent repti glow bulbs. they put off uva rays and uvb rays. do you think these would be beneficial to the plants? Plants create thc to protect it from the light.. more specifically the UVB. they also have these in those flouro spiral type screw in bulbs. Hagen® Exo Terra® Repti Glo 10.0 48" 40W in Pet Supplies - BizRate
you can get these bulbs at pet stores and i would be interested in seeing someone use these with their other lights and see if the plants grown with the UVB actually gives better buds with more trichnome production.

:leaf::leaf: Those light's arent effective for growing plants. There is a reason they labeled those for reptiles. If they were any good for growing then alot of people would use them.:leaf::leaf:

why so are they not effective? they are high in the blue and red spectrum but also have UVB which is one of the big reasons marijuana creates THC. right? maybe people just dont know about them and have not experimented with them enough to know if it would be beneficial or not.

I've seen quite a few videos/threads/reports/stuff that say adding one of those reptile lights can increase THC production in your plant. I've also heard some from the other point of view, that it's a waste of time and doesn't work. I think the general concensus is that UV lights PROBABLY help to some extent, but aren't worth the cost for a lot of people, since nobody really knows for sure. I definitely would like to try one, and as long as you have the cash for it, I recommend you try it to.

If you're trying to use the bulbs as the primary grow lights, stop it. These shouldn't be used as the main source of light, only as a little side light to experiment with and try to increase potency.

:leaf::leaf: Alot of those fluorescent's are T8 bulbs. The majority of fluorescent uses that i have encountered found T5 bulbs to be more effective for growing. :leaf::leaf:

Yeah, I'm a guru...look at all the posts I've got. :smile: I've on my first grow, a white widow. I planted 5 seeds and this one survived (lights not close enough I'm guessin'). I had an orgasm when I saw her first pistols.:weed:
She's in her 6th week of flowering, and I recently remembered an incident where someone tried the UV lights with a reflector and it nearly killed some of his plants; yet the theory of adding UV makes sense. I bought a couple 26w Repti Glo 10.0 UVB bulbs, and figured if I didn't use a reflector it'd be OK, as the guy who lost his plants said only the plants the reflector was aimed at seemed to be affected. BTW, they come in 5 and 10 ratings; I don't know if that refers to the percentage or ?
I had the UVBs on near my girl the first day and came home after the lights had been on about 10 hours. My girl was drooping; not the leaves, her stalk and branches were drooping. I had turned the UVBs off as soon as I entered her area as those rays aren't good for us. I put some long wood dowels in to hold her branches up. She came out of it, and I'm afraid to use them again until I learn more. I think you'd want the smaller strength lamp, and possibly have the UVBs on for only a short period, perhaps a few 15-minute periods or? It's going to take time to find how much UVB could be beneficial and how much is dangerous.
On a side note, I'm a complete noob, so this is a straight grow. Before UVB a lot of the buds couldn't get much light. Now she's "spread her legs" enough so that most of her buds are getting good light. It's become an interesting journey.

How old was your plant when you tried this? I would guess it would be most beneficial during flowering because thats when the most thc is created. you should test it out again. but maybe check on your plant while its on to see if its hurting it. i wonder if it started drooping due to the light or somethin else that could have gone wrong. I know that the lights have to be at least one foot away from the plant for the UV rays to reach. Good luck on your first grow! your a lucky ass to be starting out with white widow seeds

Chronic your a fool shutup.

UVB catalyzes a reaction to form certian enantiomers and synthesize THC. They would be great to use during flowering although slightly detrimental they may increase the potency.

I would say small periods through out the day. It will be like tanning as only so much THC can be made as the reaction will run out of reactants and will need to be replinished.

Im pretty sure that no one asked you what you were thinking but im going to respond because posts like this are not only funny but they really shed light on one's ignorance. Those lights are NOT for designed for growing. Im not even going to insult everyone else's intelligence by explaining what those lights are for because am Dr. Chronic, not Dr.StateTheFuckingObvious. Any experienced fluorescent-using grower would toss those pieces of shit REPTILIAN LIGHTS, for some T5's. But if you don't then have fun growing with shitty lizard lights idiot.

well you have not yet stated why reptile lights are "shitty" you just said T5' s are better but they are also more expensive plus that does not have anything to do with using UVB to increase trichnome production. the reptile lights put off a certain percent of UV rays and the rest of the light is exactly like other fluorescents

In ADDITION to CFL or HID lights they help the plants produce more THC. Only should be on for about 30 mins twice a day.

:leaf::leaf: It is true that marijuana produces THC to protect itself from ultra violet rays. It is also true that ALL fluorescent lights emit ultra violet rays. Reptile lights are just more concentrated in UV rays because it is important for the reptile you have. It would take a MASSIVE amount of any fluorescent lighting to emulate the sun in the least bit. So yeah you might get a little more THC production but nothing significant enough for it to be cost efficient or practical in the grow. People use T5's because they are much higher output than most fluorescents making them much more logical choice for the grow room. Don't be fooled by cheap gimmicks and "specialty" lighting. :leaf::leaf:

dr. chronic, have you tried this?

danky doodle, what I would do is get proven lights, and then during flower add your reptile light, as supplemental lighting. but I'd start with them pretty far away, and experiment with how close they should be.

:leaf::leaf: Even then you wouldn't be able to tell the difference. The only way is if you flower two plants at the same time in the same conditions. One plant with just regular lights and then the other with added reptiles lights. And even then if you aren't careful with replicating the exact same conditions the results may not indicate much. There are plenty of fluorescent options that are alot easier, cheap, and most importantly PROVEN EFFECTIVE. If you really want some UV rays then sit your plant out in the sun for a couple of hours every day and that will give you more UV protecting THC production than any of those reptile lights can give you. Nothing beats the sun! :leaf::leaf:

I have seen lots of people use these lights and love them, but they are only supplemental, 10min at a time 3 times a day. They produce more resin glands to protect itself from UV. This is the first time ive seen somebody say they did not work. Check out ICMag and CannabisCulture. You will find lots of people using them

then it is settled dammit i will supplement with one and we shall find out once and foar all as i have the disposable income and newly flowering plants

Here's the way I see it. There have been reports that when the reptile light is suddenly used it shocks the plant, makes it droop or whatever. Well, if take an indoor plant that is not hardened up and put it outside for a day it will probably shock it the same way right? So, maybe the reptile light does have an effect, you just need to harden the plant up like you would if you were moving it outdoors?

heres a little insight for yeah dr.chronic

anyways heres another thread for you guys to read up on that are interested in uvb lighting id deff watch the video too just click the link above.

i just started my uvb for supplemental lighting with my 400w
ill let you know the difference once i notice change.

check out these pics on page 3 topfuels post shows massive improvement

Hempbucquet over at ICMAG did a test with a UVB Reptile CFL and putting it on for 2 or 4 hours a day increased his resin by 15% or so it was worth getting IMO and I'm going to get on and try it out and let you guys know what it does for me..
