CFLs clear PVC hung vertical *concept*

Scrubs - Good call with those lamps. I think i'm going to do some scrounging around today, i couldn't find anyone locally that sells clear tubes in the specs that i want.

Sneakinman13 - Yeah If you can't get your CFLs to fit in your hood you could also build a box of sorts with a plexi glass shield and shoot some air though it via computer fans or duct work to a single blower. You can get bulb cleets from hardware stores and they are pretty easy to wire up

Tilt - Dude that awesome, picture aren't workin the the thread, but i followed your link, thats pretty much my idea but with out the PL-L bulbs. Good job on the set up too, really clean. Where did you find your tubes from BTW?

Oldbootz - Yeah your probably right about that, most PVC is thermally rated to around 260F, most CFLs wont get above 170 - 180F. But it also depends on the thickness of the tubing as well as, As for soft plasics they can melt around that temp. It was more of a warning / observation then a "DON'T DO IT YOUR LIFE WILL END",

So now comes the day to searching, i'm going to go to some of my usually places and then also search around Wacky Wallies for a glass vase as well. I wasn't quite able to track down the to clear PVC tubing, but their is a couple other stores out there for food for thought, i was also thinking that a exotic pet store maby carry acrylic tubes i think i saw some awhile back ago, but i don't quite remember (hehe pot head memory) Everyone else good luck to your search!

they are cut down safety tubes for T12 8 foot lamps. They are acrylic. You can find them in home depot, lowes by the lamps. $3.50 each. Check at micheals crafts they might have what you need for cfl

i still think that glass, perspex, pvc clear tubes, if they are thick enough will be able to have 26w cfl resting on its surface and wont melt. im going to try find a tube like this and try it !!! will post results if i can track this down.

Not to discourage you at all, OB, because I love it when someone does a controlled safe test like that - it often settles confusion very quickly. But similar to St8's experience - I had the circulation fan's supply die in my tent once and the plastic where the CFL's glass coil meets the base started melting. Good brands and cheap brand CFLs. Granted they're not made out of the same stuff we're talking about, but surely it would be pretty heat resistant as far as plastics go. (assumption)
 
When you assume you make an ASS out of U and ME :) Yeah, thats why i had a bit of concern with the bulb being snuggled up to the glass like that, atleast if it was like a little bit of distance between the bulb and the tube you would have some wiggle room for error. Those plastic things i was taking about were like ON the bulb (think one broke or something and slid down), it was the only thing that did melt and everything else was cool, plus it was in a sealed enviroment, and i think the tube is made out of PVC or of such material. And incase anyone wanted to know the bulb temp was 168 F, measure with IR temp gun, from the out side pointed at the tube with the light freshly turned off the tube was 105 F. hehe anyway i didn't get a go around today, ended up going to a green festable, where i ended up finding me self in the middle of a gay rights protest of sorts while trying to get in. So the down side is i didn't find what i was looking for, but i didn't go look either. The up side is i got some good connections for some local organic farm / plant stores hoorah. Michaels might be a good place too. The bad part is i remember seeing these damn things some where before, and it stick out in the back of my mind because they had different lenghts and diameters but for the love of me i can't quite figure it out. I did call around pet stores and places of the suchs, but they didn't have quite what i was looking for, they did have it in some neat colors though (don't know why and it was at one place). Guess it might be time to rip apart my set up to recover one of dem spiral light makers and carry it into a couple artie fartie stores, yah know, test fit!

Oh yeah, and i've been lucky with being able to acess the interwebs here lately. Might not be the case soon though, so i'll try to give a warning before dipping out. But i should be able to get some pictures up tomorrow if i can find what i'm looking for.
 
Hehe, make a friend in the auto repair field (i'm a full tine mechanic), or go to a shop and herass the service manager for the tool trucks guys name and when they come by. I got mine in a kit with my DMM and test leads, and i see them for bout 50 - 60 bucks here with a +/- 1.4% tolerance. And remember it's not cool to point it at a chick and say her temperature is "too hot" she will usally give you a pissed off look b/c you have a lazer in her eye ball
Lol and i was looking at that the other night, stoned out of my mind trying to comprehend what i was looking at, i couldn't read anything, i had the attention span of a teetsy fly. But man that was cool as hell looking at until the laptop fried. lol
How well does your cathodes work?

Hey cheers man. I noticed that Scythe make one of the temp things, I will see how their specs compare. Got a lot of mechanic types here, I can ask around :)

Well, the cathode thing is a bit up in the air. They're technically "a bit crap", heh. But one dude that I know of has grown under them (flowered at least) and for me, the results were a little inconclusive, and enough worth it to give it a shot. As you can see I'm interested in vertical lighting theories and if I pull this off, I should achieve all those benefits and have buds growing through, and around the bulbs. It's like some spider on acid went nuts inside there. It's a web/spiral of light. So I hope that makes up for the things that most percieve as the downpoints of these lights.

We'll see how it goes :D A couple of people are trying it with me but I'm careful not to "sell" the idea. Just put it out there. I soaked some seeds last night and I think the others are close or even ahead.

hope you guys like!
 
Looks good sneakinman, once they get going make sure you have that light just about kissing them. If you have too (not saying that you haven't already, just haven't seen it) strap a computer fan too the side of it and get a little air flow up and out, thats if you have some heat issues.

Scrubs i like it, looks solid hopefully it works out for you, i would be extremely interested with the out come with those lights.

Thanks st8! One thing I thought I'd mention since it concerns the general subject - cutting glass! When I were just a lad, my mum got into making stained glass. Being a kid I was very interested and I learnt how to cut glass. As far as cutting a rectangular piece for a hood, it's very easy. Just buy a glass cutter on ebay cheap, and type glass cutting into youtube, and behold the ease. There is one particular video with a woman demonstrating and it's great. They cut the film so it's rapid fire cut after cut after cut and there's no way you could screw up after having it drilled into your brain like that.

Also, it's surprisingly easy to cut glass bottles for mini tubes, or something like cork's idea earlier. You can set up a little rig so you rotate the bottle and the cutter does it's thing in a straight line, but shit, bottles are not exactly hard to come by, so if you explore youtube you'll see the demonstrations of tieing string around the bottle and setting it alight. Might take you a few goes, but you'll get there. No cutting tool needed. This was a common old trick out in the bush in days gone by.

Anytime the glass is cut, as long as you didn't F it up, it can be sanded down with sandpaper to a smooth round edge, just be careful of any extra jagged bits.

So drink up boys. :friends:

Sneakinman13 - Have you thought of starting your own thread? I am sure we could give you a hand getting that dialed in. I am interested in seeing what you got going.

ya i got a thread... its called sneaky sneaky in the indoor soil forum.
all are welcome!!!
ima add it to my sig here in a min also.
 
Well in my venture today i turned up empty handed. Nothing at any of the arties farties stores, nothing at wacky wallies, so i have up on that route and started looking online. I found Acrylics, PVC, glass tube in all diameters and lengths. So thats going to be my route once i do some more research on the pros / cons on the materials.
In the mean time i started getting some soil ready for my rubbermaids, i use a product called epsoma bio-starter which has fungi and happy bacteria, but it should cure for a week or so before dropping seeds in. Thats where i'm at right now, hope others are having better luck

I like to get stoned and walk through the local antique stores. I get all kinds of cool glass jars for storing bud in and found some perfect 4" cool tubes for my cab. I get a kick out of walking around and thinking....could I grow in that?

not exactly what you are planning, but maybe you can get some ideas. The clear tubing is acrylic not pvc, it also comes in lexan, diameter 6" with 120w cfls and the white painted wire screen cylinders are 8 inch diameter with 85 watter (24 of them :) ). Cfls can touch the acrylic or the lexan and not make it soft at all or affect it, but I tried not to let them touch. The temperature tolerances of acrylic are pretty high. The clear tubing is expensive.

Hi all,

I have also been planning a grow with vert. CFLs. I use 4 x 24w PLL CFS in my grow cab (15"w x 15"d x 20"h) and although I got 1oz from my first grow, I am ultimately aiming for a 2 oz yield and I think switching the lights from horiz. to vert. is going to be the best way to get there/ maximize the yield from my cab.
Until I happened on this thread I was planning to sandwich the lights between the plants using lexan or glass. E.g (Top view of cab):



but I am liking your tube idea ST8 and I reckon I can adapt it to my needs by using a clear protective sleeve for a T12 lamp to shield the plants from the PLLs :

http://www.formatt.co.uk/cocoon-lighting/clear-safety/cocoon-lighting.aspx
I realize that plastic will block some of the lumens, but the plants should still get more of the light from the lamps than they would with a horiz. setup with a reflector as there is no restrike.



I currently have 2 bagseed plants that I switched over to 12/12 a week ago. Fingers crossed they are both females, and if so I plan to re-jig my lights and post a few pics.

The potential issue I can see is that the plants will grow lop-sided as they will lean towards the lights, but turning each plant end to end periodically should fix that......anyone else see any issues with this plan?
