Reptile UV-B lamps to increase THC production...

Hi,

I have been reading Ed Rosenthal's new book that came out this spring, the Marijuana Grower's Handbook (official Oaksterdam course book..heh).

http://www.amazon.com/gp/product/B003ZUY16G/ref=pd_lpo_k2_dp_sr_2?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=0932551319&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0E3EH1T9K2RHYBQ9KZ7B

My question is, he mentions how during the flowering period that THC can be increased substantially in direct relation to the amount of UV-B light the plants receive. This stimulates and increases THC production...at least thats what he claims.

I looked into Reptilian UV-B heat lamps used to heat and assist reptiles. They make these in T-5 lamps or CFL lamps. I was thinking about putting up a side lighting panel of T-5 lamps...one of the 4' long ones, 8 lamp ones. Go half UV-B reptile lamps, half 6500k cool flouro tubes (to supplement lighting in flower). What do you think? Is this a good idea?

Has anyone heard of using UV-B lamps or had direct experience with them? Do they really work?

Ed claims you should supplement 1/10 of your flowering wattage with UV-B lamps. ie if your using 1-1000w HID light for flower, you should also use 1-100w Reptile UV-B lamp.

Thoughts, comments?

Thanks!

sounds like it should work, i have also herd of the uvb inc thc production, but havent done much research. Ill just suggest to get a uvb lamp with the highest rating, which is ten, i know this bc i had a chameleon and they needed high uvb to absorb calcium or they get bone diseases. Ide like to see if this works

There's someone doing a test right now. Here's the link- https://www.rollitup.org/grow-journals/372218-frigidare-2-indicas-infrared-spectrum.html

You guys rock! Thanks RIU! Greeat responses. Now I just gotta get some money saved to get this side lighting project rolling. Ideally I want 3 of the 4' 8 lamp flouro panels. Run them all alongside my flowering chamber. Gonna cost about $900 or $1000... But it should be fucking badass side lighting when I'm done!

Edit -- here's an interesting short read from the US Skin Cancer Foundation regarding UV-A and UV-B lights..

Nice read. +REP

Ok apparently Daniels is already trying this...was reading his thread. Riddle says to use only Reptisun 5.0 lamps as the 10.0's are too strong...and to only run them about 15-20 mins 2x/day and keep the lights 30" from the plant canopy. Soooo...I probably don't need to flouro panels. Can probably just dangle 1 CFL lamp above the canopy for every HID light I have...so 3 total should do me I think. Trying to figure out the best way to do this..
