so i learned this here but when i searce i cant find the post.

any way i have been using a 10.0 uvb light it runs in the middle of the day for 6 hrs, i have been useing it for 4 weeks now in my bud room with 400 hps wow. i have seen a diffrence allready.

it is virtical grow so hps is in the middle and my uvb it to the right. 6 plants on the floor and 8 plants on the second shlef about a foot and a half. 2 plants on each 4 walls.

so the plants that are on the shelf to the right have a ton more thcromes then the plants on the left and thefloor.

now i am going to move the uvb to the other side of the room, but i might need more then one. i am going to do some more trial and error.

is any one else useing this yet?

not yet, but was planning on it after I read that it tricks the plant into producing more THC as a type of 'sunscreen'. When did you start the UVB?

lets see some pics

do you wear lots of sunscreen when you are around the UVB light? you should be VERY CAREFUL because you can get burns and skin cancer. but i have heard great things about UVB. how hot does UVB get?

It gets pretty hot. What I do is I use one 200w reptile sun lamp and rotate it over a new plant every day so they each get a little coverage. Yes UVB rays are dangerous but as long as you are not hanging out in the room for hours and/or staring at the lamp directly you do not have to worry any negative side effects.

Right now I'm using a UVB reptile lamp with my other two t8 fluorscents (waiting on 400 MH). While I haven't noticed any major differences yet the plants do seem to be bushing out more; however, the real change, I expect will occur in flowering...I'll tell you all the details when I start in about 2 or 3 days
