if added too soon, smaller more resinous more potent & healing buds...
Your Grandpa's Weed or is UV supplementation really needed?

its only unsafe if it glows green with the lights out.......its uv, not gamma radiation, bruce banner, it leaves no "residue"

Thanks guys.
I think Pure UV is too powerful for one girl in a 3' X 3'. My height is also limited to 160cm(5.25 feet), so it would be easy for me to get a less powerful one because I want to use the same timer, to run them 12/12, and not to be that dangerous to have in the house.
I decided to get a double bulb fixture, maybe LightWave 2 feet long, 2 tube
and run a pure PAR bulb and a Zoo Med Reptisun 10.0 T5-Ho Uvb, or a Arcadia T5 D3+
both in 24W, I'll get what I can find in Europe. but I noticed the UVB bulb has 22" in length, but the Agromax PurePar is listed as 2 feet in length.
Can someone tell me if I can mount them both securely in this fixture?:

the pure uv fits in the standard single t5 housing i picked from htg. the entire housing must be 22", i never measured though, just switched bulbs, and rock & rolled from there. in the 5ft tent, zip tied to the top of the frame, no reflector.

Well, it seems htgsupplys doesn't sell outside US. Too bad, I really liked the GrowBright fixture.
In Europe I found fixtures that are unnecessarily expensive.
I found on Alibaba a good quality 2ft aluminum fixture, 2X24W, a Fulham 48W solid state ballast.
They're relatively cheap, but it will take a month for them to arrive if I don't find something in Europe.
I didn't find the Pure Par bulbs anywhere. I'm sure they are, just under a different spectrum name.
Can anyone recommend a very good substitute? Or maybe we can find the genuine bulbs somewhere else?

hortilux has some t-5 power veg bulbs that do pretty well. of course the arcadia & ati aquarium bulbs work also, actinic, @RM3 & his buddy illumination(r.i.p) did more research on them than i though. i only bought a cheap 14k 400 mh from amazon, a violet colored bulb.

Looks like you prefer the single cola plants. They sure are easier to trim!
How do you like the grow bags? Do you have any problems with root spiraling?

I don't prefer single cola. There are two plants I topped in there. One with four to six tops the the other with four.
I went perpetual. Kind of a sog. Its just easier to handle the plants single cola. A couple of the taller ones are clones.
This is my first run using the grow bags. I ordered a 25 pack and they sent me 100 of them.

are you growing "autos" my friend
whitebb2727
Well-Known Member
Growing photo plants. I listed the strains. There are 6 little ones that are 3 strains by rm3. The taller 2 are c99 and special haze. Couple other strains in there.
The two smallest are autos for the current comparative grow. Growing them 12/12 from the start.

Would this T5 bulb do any good? http://arcadia-reptile.com/fluorescent-lamps/t5-d3plus-desert/
Only one I seem to find locally.

damn my brain is fucked because i read the complete thread from the start till end in one piece, now i need a break but this thread is watched and i got to show some stuff i found from searching i did about UV-radiation 
mr. childs

this bulb has 12% uvb + 30% uva
the agro pure uv has 75% uvb + 25% uva

ok so finally i found some time to write here 
in my own searching about UV-radiation ( while searching i found this thread here ) and its impacts on plant growth i tried to solve it from a different end. i was thinking about the fact that if UV-radiation has any influence then it has to be absorbed.
i alrdy knew that for example chlorophyll a and b got their absorbtion peaks in red and blue and thats the reason why lights using red and blue spectrums end up with a purple.
the proof that this works best did Theodor Wilhelm Engelmann when he measured the effects of different colors of light on photosynthetic activity. the results where that the most photosynthetic activity was seen at the colors of light that match the peak absorbtion.
so i looked up some other absorbtion spectrums:
carotene
peridinin
so what you can see there is always an amount of UV-radiation that is absorbed. sadly these grafics i found dont got further down the wavelength.
i found one grafic that goes further down for carotene:
as you can see there is even an absorbtion peak at about 285nm.
so i was sure that if you can control the amount of UV-radiation to a level where it helps more than it destroys then you would have a wavelength that also pushes some photosynthetic activity out of a plant. i would assume there is a factor between the absorbtion percentage and the radiation power that would be best at certain wavelength.
maybe this would not be such a big difference as if u would grow a plant only with blue light and then found out "hey there is red that helps my plant also, lets hang some red lights", but there has to be a positive impact in whatever way. photosynthetic activity cant be enough for the cannabis growers right?
so i tried to find more information, i found that 2 researches and after that i found a link to RIU haha. everything i read here just told me i was right in a way
so now i am here and shared my findings i hope they help. if i am wrong please tell me cause i love to learn things from the pros.

Yeah
Got any tips for C99? I got a couple of feminized beans from a buddy and I'm going to pop them this week.

C99 is a easy to grow strain. I've run them from female seeds an blimburn. They must have come from the same lineage or cuts. They are similar. I lost a good pheno
.I should've cut a clone. Most seem to smell of fruit and skunk. More of a pineapple smell. The one I lost didn't have the skunk. Pure fruit. The one I got going now smells like fruit loops.
It can handle a little heavier feeding than the more touchy sativa. Let it finish. Even a few day can make a difference.
Don't use bloom boosters on it.
This one is looking good. Putting on frost.
