Intersting to say the least.

I used 80w of 10.0 fluoro tubes in my grows and had some real dank herbs but I'm not using it this time so I'll see if it makes a real difference I donno... I know that hortilux makes a difference, and an additional 80w would probably be real good for the girls but the 4 ft tubes are too big for my setup... if I can get my hands on some cheap 2 footers I might throw em in for the last month or so.

Hey man ... there some good info compiled here. Good luck and Walking On!!~~~~~

"A House Full of Gratitude Has No Place for Fear To Hide"

I'm about to start my first grow and found a thread that posted a published scientific study on UVB effects on cannibus. (atleast it reads like a published scientific study) Effects of UVB radiation on THC and Trichrome Production

I've been searching for info on UVB since I still have a day or two before my 400w lights arrive. (I just found out about UVB this morning) I ran into a guy that warned against using Reptile Aquarium lights because of the ammount of UVA radiation which according to him can harm your plants. Is there any truth to this and if so, is CFL the only other alternative?

Also, I heard that MH gives off UVB radiation. If it's true, does anyone know their output? To me, mixing an MH or two in with your flower lights seems like a better choice if you can get the same UVB exposure.

Also I read about something else you can do to increase resin production. I got it from the book marijuana Home Growers Guide. It reads like a text book, is very thorough, and I've yet to find a mistake in the book. The book claims that if you pinch the tip off of every leaf as soon as the new leaf appears starting with with the very first leaf, the leaf damage will cause the plant to produce enough resin to carmalize the entire plant in resin. The plant will not get as big of course because you are removing leaf material, but only about 1/32 of an inch per leaf so the loss of yeild shouldn't be too bad.

I'm going to have to start flowering my first set of plants after only a month due to a money flow problem, but I was planning on experimenting with this on my second grow. If anyone else wants to experiment first, please do. I can't wait to see if it works.

If I'm going to keep a journal on any of UVB info am I going to need a special camera or is there a microsope out there that incorporates a camera?

Forgot to ask another question, I read somewhere (I think in that sudy) that when you use UVB the trics can come out clear instead of being colored. Supposedly it's because the UVB somehow allows for a more pure something or other. My question is if the trics are clear, how do you know when the plants ready to harvest?

Tahoe, love the avitar. My girl told me she doesnt want everybody seein her behind but I assured her I would not show anyone.

I'm excited, ReptileUV.com is selling UV Metal Halides. I'm thinking this may be the cadillac of UV lights, but I can't read the diagrams.

Can anyone tell me if these have a better UVB output than the reptile or CFL lights?

UVA & UVC also, can you tell the outputs of these two from the UV Diagram?
