Hey Weez',

Your pot porn pics look good, finished product sounds quite tastey, you should taste the diamond I mined out of the 10 shivas skunks we grew out, got one dats goin' to be a killer. I also saw your updated albums, who says a square peg don't go into a round hole (bucket).

And Horse,

You just starting to see da boys put thier heads together here, to a few hardcore growers the science of light wavelenghts and there effects on plant growth can become a relegious experience of sorts.

I find this fascinating. LED and advanced light technology have always come off to me as an intimidating read. I feel like I wouldn't know where to start reading to understand it all. Perhaps Weezard can point me in the right direction of a thread or something that would be a friendly read for an LED noob. I'm obviously not a plant idioit, as it is my major of study, I just have not had the light experience...

Thanks to all, I'll be keeping up with this one

Maybe Weezard has a good source for this info, not sure. I got interested in it about 3 yrs ago after taking a horticulture course(s) at a community college. I was surprised that 660nm red light was heavily discussed and mentioned in the text books, plus the importance of 770nm far red. That's where I started and then searching for scientific papers that delt with the subject. A whole lot of research has been done, alot is not available tho cause it is directly related to proprietery interests by sponsoring companies.
NASAs LED stuff made me start to build (5mm diodes), use and experimernt, and I'm always still looking for more science.

I've got some clones rooting, so hopefully I'll be able to do a sort-of side by side. (top and bottom) Will have to remove some bulbs from bottom (late veg) space to make 'em even-stephen, but if Farmer Bob's advice is correct, I might not miss the missing lumens.

Kinda off-topic...but this is my latest veg closet. Half clothes, half growroom.

The drip trays are lined with aquarium gravel, so I don't need drainage rocks taking up room in the pots, and makes transplanting a breeze. Clone tray cover is a sheet of plexiglass. Holds 12 clones. The plastic tray and bulb bases (outdoor security lights) are both from WalMart, UV light is in the bottom section. The shade cloth keeps the light from glaring off my computer screen. (and no signs of the bulbs melting it at all) Has an unlighted upper level (not shown) for a tub of just-planted seeds. (versatility)

Anyway, I guess we'll see how it goes. :jointsmile:

Nice setup Rusty, I always like to see shelves with multi use areas as they are the most space effiecent for indoor home growers.

Look forward to some more experiments and I think yours could be a good one. I know that Dogznova peaked my interest with the "fast blue" concept. I may try to do a run substituting UVb bulbs with some actinic whites. I realized in the one grow I use a super actinic white (435nm peak) for clones and seedlings 'cause it really helps with root production, and if we veg under the combo of 6500K fluros and that actinic the young plantlets stay short and compact. Plus another experiment I want to try is using some UVb during the vegative growth to see if there is an improvement. Only problem with that here in my personal grow, since I grow SOG, they are only vegged for 2-3 weeks, the time it takes to transplant the clone plugs and establish them into the delta blocks.

BTW, since I started this thread in the OP I clearly state on or off topic is ok by me.:thumbsup:

All UVb free from birth.

Ummm...if they're outdoors they're getting a better UV light source than any artificial source us indoor guys could hope to provide.

The buds were grown under 660/ 470 indoors, No UVb at all
As was the front bud in the third picture.
The girl in the background is a sun grown AK-47.
The foreground is a White Widow grown under leds.

Now that I can get decent sized buds indoors, my concern is potency.
It may be that UVb affects isomerization in a positive way that balances the degradation.
O.M.s a better judge than me 'bout dat.
I get baked on one hit and objective quantification becomes very difficult.

Got some lungs visiting from the mainland soon.
I'll give them numbered samples and try to get a "1-10 scale" answer on potency.

Thanks for the myths link. LC-S knows what she's on about.

Mahalo,

Nice setup Rusty

Thanks. Necessity is the mother of invention. :thumbsup: Plus, I'm a woodworker and have the tools and stuff.

I have a dual-bulb Sunpaq ballast from coral reefing. Plant's don't do well with just the "dual actinic" bulbs at all, and the times I've tried, quickly switched back to either the dual daylight bulbs, or CFL's. (dual actinics: square 4-pin 32w bulbs, 420nm and 460nm)

Plus another experiment I want to try is using some UVb during the vegative growth to see if there is an improvement. Only problem with that here in my personal grow, since I grow SOG, they are only vegged for 2-3 weeks, the time it takes to transplant the clone plugs and establish them into the delta blocks.

I've been giving around 4-6 weeks veg. Any longer veg than that, and in flower the plants will stretch way beyond my 3' effective light range and is pretty much a waste.

I'm all set-up for UV in veg, once the clones root. I do have a couple of mom's in there right now, but way too early to expect a difference.

Weezard: Sorry. The picture of the outdoor plants threw me. :thumbsup: A nice nugget in the pocket is always a "10". :jointsmile:

Way to go Rusty, from coral reefing to coral reefer, I love it.

I found the the aquarium people have alot of cool stuff...it's where I first saw the IceCap ballasts for driving fluroescents. Plus I've been impressed with the double ended MH bulbs found in thier hoods to have a much more balanced light foot print then the mogul ended ones commonly used by growers.

And hey, LED moonlights are pretty cool.
(now if I was into lunar cycles, I might just go and try those)LOL

LMAO!
