If not i'm thinking about taking it to a friend (who happens to be a police officer, haha) and getting him to use a refratrometer (sp?) they use it to check car window tent to see how much light passes though. FOOD FOR THOUGHT!


DO NOT DO THIS! What are you planning on telling him for your reasoning??? I do not like this idea one bit! Cops and growing DO NOT MIX!

I thought he said he was going to take the tube over to his buddy. I don't see any good way of asking to see what the light penetration of a round tube is. Sounded like a bad idea.

Oh don't worry, it probably still is a bad idea, lol, you gave good advice. Depends on the specifics I 'spose. Childhood bonds can be pretty strong, so maybe they grew up together or something. Some cops do smoke, as well.

This thread reminded me of an old design idea I had. I drew it up, maybe someone can get an idea from it. It's a version of a stealth vertical cfl with partial cooltube.



The original idea was a way to utilize a single cfl or other very small wattage bulb in 360 degrees for maximum potential. Then later I had an idea for the lamp with a bulb at the top of the inside, months later I realized the two could be combined. I hope the pictures explain it well enough :abduct:

The original design was inspired by Tpyn btw, had to go "remember" his name.

Hey Stealth, your picture isn't working. But it sounds so great i would love to see it.

Grouchy - Hey don't worry about the "police friends" it's more or less like "Police family" and he wouldn't think twice or even question me being involved with anything. Being weird in life has it's advantages he'd probably think it would be normal of me, i've acted for some pretty weird things sometimes. Like if he would run radar on me when i was trying to see if the 3 angle valve job i did when i rebuild my motor actually made it run faster (i knew my top speed was 135 before, was 140 afterwards). Was way cool, felt like i was doing something i shouldn't. Long and short of it he wouldn't ask. Could just stick some tint on one side and tell him i wasn't sure if it was legal or not :)

Back to the tubes i found a couple companys where i can get a 6 foot cast acrylic for about 20 - 30 dollars, Now what i'm interested in is UV blocking properties that some of these acrylic have. The real question would be how does UV effect the plant? I tried looking into it breifly but didn't get way too far, more information on UV-b effect on humans. I'm think, and this is on a random speculation, but if i can get the lumens / light spectrem just right, uv shouldn't matter any. But i'm just guessing

Doesn't help much but since I have it at hand:



Have you seen the video that was in DIGITALHIPPY's sig about uv? I just found the link but it's been removed from the youtubes. I sent him a PM to see if it's hosted anywhere else. It was great.

Hey guys,

UV-A spectrum damages plants and is not healthy.
UV-B spectrum encourages the plant to start up natural defense mechanisms and seems to have increased trichrome development for some ICMAG users.
Red and Purple Christmas lights also help with the light spectrum, i have read that they increase the far-red light which makes the plant focus its energies on growing taller and pushing out foliage to seek light.

Another tip i read is to give your plants blue only spectrum for the last week or two of their lives, which further encourages trichrome growth and natural defenses.

In my own experiments, i have some CFL's and flouro tubes and a HPS, the spectrums i use are 2100k 2700k 5000k 6500k and the end result is a very golden colored light and the plants seem to love it. buds that grow closer to some of my daylight CFLs but still under HPS light seem to have increased density and structure. I cant say about trichrome growth increases because im always running new strains and haven't got my head around how a particular plant reacts in all situations, so if there were more trichs i don't think i'd have realized.

Hope this helps
 
No i didn't get to see DIGITALHIPPY'S sig. Wish i did, but according to the chart UVA does nothing, and that every other visible color helps the plant. I don't think a CFL have any UV emitions anyway.
Anyway, yeah clear cast arcylic will probably be where it's at. Now to figure out the exact ID i need for my tube, incase anyone else is looking at this, these tubes come in two messurments ID (inside diameter) OD (outside diameter). Depending on what my messurement is, i'm going to want the OD to be .125 to .250 bigger then your ID, and i'm guessing the smaller of the two numbers would probably be better.

So objectives for this week.
Measure my biggest CFL,
Find the right tube,
Order, wait, recieve
-we'll see about putting it together once the tube comes in :)

I've seen a lot that A is no good but I'm pretty sure the video discussed A being useful in some small way. But I may have misunderstood. Dude was tokin' on a doobie in the vid and so was I. :smoke:

CFLs have a lot of uv as far as I'm aware. I just looked at an 8 or 11w daylight cfl and there was a definite hint of violet. I noticed this on a 23w daylight too.



Go check for yourself with a cd, it's hella interesting. Doesn't seem to show on camera but it's near the writing. Just make sure no other light is messing with it.

or get a small UV-B flouro tube and stick it up somewhere, it doesnt have to be strong amount of light, just its presence will increase trich growth apparently.

i wouldnt trust the CD spectrograph too much, human eyes have certain limits to what they can see. some bulbs come with detailed light spectrum information, maybe they'd indicate if their daylight bulbs have UV-B in on that information?

I would trust the cd thing. That's the whole point of it - so we can see the real colours that we can't actually make out in the light via naked eye. Granted you should make a spectrometer to get a better picture but it definitely gives you a good idea what spectrums you're dealing with.

Great link here, I think StealthDragon posted it on the ccfl thread.

 
According to this chart from Green Pine Lane plants use all the spectrum from UVC to IR.

any colors that your eye is looking at will be in the visible light spectrum. plants can use colors that the eye cannot see, but industrial spectrograph machines can detect all kinds of light depending what they are made for. ie. gamma ray, x- ray, ultraviolet, visible light, infrared, microwave, radiowave. those are all types of light. plants dont use them all but they do use ones that we cant see with our eyes. thats why i say rather use the manufacturers light spectrum info if they have it than use a cd.

in experiments with rice plants Navin Kumar Ambasht and Madhoolika Agrawal found that increased UV-B produced more complex flavanoids and decreased plants abilities to break down hydrogen peroxide into water and oxygen. it also decreased the total biomass of the plants. If this holds true for cannabis, then we can assume the pro's as better flavors and potency with the cons being decreased yield and ability to metabolize h2o2. interesting stuff.

Im absolutely sure you can grow the shit out of pot by using large CFLs that shine through acrylic tubing :) The rest is just talk. Im glad you found a cheaper source than I know about, get it and do it, it'll be fun.
 
Ohh yes, fun will be had. I think for right now, i'm not going to care about details like UV or no UV, i think i'm going to start focusing on how i'm going to set the bulbs in the tube, and get some mesurements of my box, maybe check up on the soil i got set up like a week ago. You know do to thinks that are usually put off for awhile. Maybe even drawl a paint-a-gram or two. But untill all that i guess i have to spend some time down at my garage taking to my stickfigure friend Leo, Leo is a dick btw he never talks back...
