UV B to increase THC

Puffin Afatty · May 7, 2008

Howdy Grow Folks!!!

:hubba: I have been interested in trying UV B to increase the conversion of thc in the resin heads. Have any of you tried this, and if so, what regimens??

Have to plead ignorance on this one Puffin. Care to elaborate a little bit?

:hubba: I saw a video on youtube. [youtube.com/watch?v=IPcpt3Be28o] discussing the merits of UV B on pot plants indoors. I had been previously reading about it on OG for a while and even got a couple exo terra reptiglo 10.0 UVB Bulbs. I am gonna start dosing SnowWhite with them again.

I've read about this too. I think it had something to do with the speculated reason why MH produces a higher potency bud. Can't recall. But it looks sound.

I hadnt recalled the MH issue, but it seems that added UV B increases the conversion of cbd's to thc. I am gonna try it on SnowWhite and see if I can get the trichs to go amber earlier than 14 weeks:hubba:

Puffin this was a very good little documentary. It all seems to make sense to me. I love how Mr.Green goes into the scientific aspect of THC production.

Yes, I thought it good as well. HippyinEngland was the one who tipped me to it 1st.

:farm: I know the UV B will kill the mildew, and I kinda think it would also distress the mites, thrips, knats, etc., eh?? perhaps there is more to this UV B than meets the eye, eh? :rofl:

agreeeed UVB stop's mold, and helps THC i have a little talk witm my friend in Amsterdam and and they all use UVB bubs in addition to HPS .

Caution:
UVB can couse skin cancer ,always turn lights off when u enter just for safety. (u just spending there few minutes would not harm u but in a long run it may)

:hubba: Thanks Brouli!!!

I know the mold is killed by UV B, and It would be nice to get rid of the NSP's.

You should make a UV B/HPS Grow journel.

How is UV A for growing compared to UV B?

Cole · May 11, 2008

Whats the difference?

IllusionalFate · May 11, 2008

Different Kelvin spectrums. I think UV A is around 10k.

Be careful with the UV-B, it can "burn" your girls. At least that is my experience. I need to find a way to moderate the amount of UV-B as my grow area is very small.

bombbudpuffa · May 13, 2008

UVA 400 nm - 320 nm
UVB 320 nm - 290 nm
UVC 290 nm - 100 nm

liermam · May 14, 2008

As far as I know, the progression in trichomes goes from THC-> CBD as the harvest window passes. I really don't understand how the exact opposite could happen...

Brouli · May 14, 2008

Everyone i've talked to says "get UVB in there" - There's a lot of evidence that UVB helps plants, working on the variance in UVB concentration in different parts of the world. Those reptiglo bulbs seem to me to be a good idea, they shouldn't be too harsh being designed for lizards - going to use one myself from day 1 in flowering

Brouli · Aug 19, 2009

puffin im curies have u had any good results ???
