I just know you will love the Tangi Frank she's forgiving and a winner . Perpetual is forever .

This will be my third time growing the Tangi....and I agree! It is some top shelf smoke, and easy to grow!

I hear ya...I had it set up for a perpetual grow a few months back...I went through 3 cycles or so. I got a wild hair and decided to finish up the whole thing and do a photo period grow. I think I'll just head down the perpetual path again....it kind of gives me a little more freedom, in my opinion.

I want to run a few photos soon. Might stick a few in with autos and just veg them til the autos are done and have like 2 monsters left to bloom out. And have been thinking of ways to run both in 1 tent. Maybe half scrog the tent for the photo side? Lol "future planning"

I agree. I don't think the way to increase THC or other cannabinoids is by way of lighting. The plant cannabinoid system is not that well understood to my knowledge. I'm still reading on it though. This link has few sources, but he mentions the same thing. Lot's of cool notes after the first paragraph too. scarring, and such to initiate flower, etc.

"Resin heads may serve to break up the rays of the sun so that fewer of them strike the leaf surface and raise the temperature."

this, is how I suspect that UV light would react. It may pass the resin heads easier, but that assumes there is some receptor pigment. I don't know of one.

ok so i read the full article ( damn what a work if english isnt your main language ) but this guy mentioned something i also came across. he mentioned the light sensitive pigment phytochrome.

since it is mostly about the wavelength-absorption of different parts of the plant that put manufacturers to ending up with a mix of blues and red you can mostly see wavelengths between [XXX] like u can see here on the pics, this matches of cause ( i hope everybody knows that, if not look at it now. i need it for the rest of this answer hahaha ) the absorption of chlorophyll a and b.

chlorophyll a: peaks 429nm, 616nm & 664nm. ( but take a look at the UV side down to 350 nm. sadly these graphics dont go further down the wavelength )

chlorophyll b: peaks at 466nm, 601nm & 650nm. ( but again take a look at the UV side down to 350 nm. sadly these graphics dont go further down the wavelength )

another example is chlorophyll c: mostly found in marine algae. peaks at 447nm, 581nm & 631nm. ( but again take a look at the UV side down to 350 nm. sadly these graphics dont go further down the wavelength )

another example is chlorophyll d: mostly found in marine red algae and cyanobacteria. peaks at 400nm, 455nm, 655nm & 699nm. ( but again take a look at the UV side down to 350 nm. sadly these graphics dont go further down the wavelength )

i just go on here cause it makes su much fun for me:

karotin peaks 445nm & 474nm ( look at UV ).

peridinin peaks 439nm 482nm ( look at UV ).

phycoerythrin peaks 412nm & 539nm ( look at UV )

phycocyanin peaks 409nm & 613nm ( look at UV )

zooxanthellen peaks 434nm, 635nm & 675nm ( look at UV )

a better pic i found here: ( very nice view into the UV )

and now the mentioned phytochrome in both of its forms: ( also a good view into the UV )

better one from a study i just found:

so you can see, depending on which wavelengths get the most energy into the plant via absorbing it ( the energy they need to grow ) the more u try to go these peak wavelengths.
thats why u end up with a blue and red shape light for growing plants that grow on air ( not under water ) that when mixxed, looks purple.

the interesting fact is, that a huge amount of wavelengths in the UV sector get absorbed. so in my opinion there has to be an impact of UV-A-B-C radiation.

sorry for the long post, i dont got a potato ( maybe some 9gag ppl here haha )

maybe @AMARE-TECH-Vic can bring some light in this

I thought about doing this! My plan would be to start the auto's....wait a month and start the photo's. That way the autos would finish without the photo's getting so massive that you can't grow them out.

To tell you the truth though...after doing a crop of photo's (I grew photo's before I discovered auto's) I remembered why I like auto's so much. I'm not saying I won't grow photo's again, maybe outdoors or something, but I feel like the room in my tent (and electricity for the light) is better used for auto's. Just my opinion.....

maybe i should start an extra thread for that UV thing? what u ppl think ?
