UVB BULBS

This was off my bulb. 24" 20W Floro. 30%UVa 5%UVb. I didn't go with the 10% cause I've been reading about the potential harm to you and your plants. I'll start with this 5%, and if it goes well I might move up.

Couple things to think about:
1- UVB is harmful; don't enter the room with that light on, and if you do, be certain to use eye protection.
2- You are making more resins, so provide more available carbon for the plant to use. This is the ideal moment to start giving molasses at a couple tbsp per gallon as a safe carbon source.

Yeah take precautions but that is excellent that it works.
Any particulars on bulbs your using?

I tried to find the bulb online it look likes a cfl and it says gives 10% uvb and i have it slowly moving around the plants on a light mover I rigged up. The light is designed for reptiles and I got it at petsmart. It is only on about 4 hours a day.

Thnx Stinky I did set it up so that I turn it on and off after exiting the room.

Stinky I have been giving them only 1 tbs per gal of molasses I should up it then?

Well you know me stinky, molasses is already part of my regimen. As I have read though, it would seem that the Glandular trichomes concentrate the UVb to synthesize more CBD into THC.
I'm using a repti-glo 5.0. I chose that because the 10.0 seemed too intense. On the box it read "for use when a screen is on top of your terrarium blocking some of the UVb from your reptiles". Plus then there is the abundant warnings about potential danger of UVb.
I have my light "door triggered". When my door opens, The UVb light goes out.

ooh. triggers sound technical....awsome!

any noticable difference withy the uvb?

all the bulbs in stores are like 40-50 and only like 10 less on ebay.....

we should merge this w/ the other uvb thread

merge it if you must....but as far as i know about these bulbs they supposedly produce more resin glands in the plant(s) in which produces more crystal on your bud and leaves....i went out and got 4 of em little buggers and the effects on my blueberryxbubblegum are amazing!crystals growing everywhere and every new leaf is even more packed than the older bigger leaves.....thanks for the help guys....

I can't say anything about the results until I smoke them. I do notice my girls packing on more crystals and smelling pretty pungent, but its due to note that this is normal for 7 weeks into flower with this strain.
On the plus side, The one I'm harvesting in the next 5-6 weeks is a sativa dom. then about 4-6 weeks after that, I'll harvest my indica dom. This will give me a good idea about which type reacts best to the added UVb.
edit: The trigger is very simple, they sell them for home security systems. its a very simple pressure activated switch. a hole must be drilled into the door jam, the switch goes in the hole. When you shut the door the switch is depressed. then just wire in and your done. Be sure to use proper electrical safety when attempting this.

I got mine for 15 at petsmart I didn't see it online but in the store they have them and those screw into a regular socket
