heres a thought
why even use glass tube............... (i know,,, there round)
but what if you get a sheet of flat glass and have it cut into 4 - 1ft by 5in slabs then find some way to put all for pieces together that will be heat resistant , something like a cool square shaped tube this will still alow you to grow on all sides for those vert. grower and grow flat out like in hor. growing

but i could be over thinking it

Thats actually not a bad idea. You could get glass pane much cheaper than tube. the corners would create lines of less lumens though, but in a pinch it could work. Also if were willing to do squares then why not triangles. Less corners.

Thanks for the idea bro I've been looking for diy cool tubes and that may just be the cheapest way yet.

what if you build a wooden box and for the top use some glass, like a glass square coffie table then on top of that place your lights , now you have the lights in differant room then the grow , keeping your grow the right temp - so put simply, you have 2 rooms, top & bottom devided by a sheet of glass in the top room you have ballast and lights in the bottom room (under the glass) you have the grow - you would'n have to move the lights just the grow start it at the ceiling then move it down - now , idk about large grows, but for small ones maybe in a diy 2 level box like maybe 5ft tall by 3 to 5 ft wide and just as deep, it could work- how much is a 3x3 or 5x5 sheet of glass-- and then you could just cool the top room or compartment

actually, that was my first grow box design. A cabinet with another small compartment above the main chamber for the lights and a sheet of pane glass that the lamps just rested on.

Good design for a stealth small grow but the spac limitations being fixed cause problems if you want to grow bigger plants.

But it is a good notion to seperate the lamps from the plants. You just exhaust the lamp chamber and dont olose your CO2 in the grow chamber. Also not being able to move my plants was not great, if you had a pulley system where you could move the floor of the grow chamber and plants up when theyre small and lower it as the y grow that would be slick.

Back to the tubes...I just went strolling around my local Walmart and saw a glass vase that would be perfect, for $10!!!!

slight taper at the rim but about 12 in tall and 5.5 in wide and pretty thin glass too.

The only obstacle is cutting off the bottom of it. Any thoughts?

I am thinking a band saw and water to keep the dust out of the air and just slowly cut thru it. For $10 bucks tho that can't be beat really

i bought a candle holder that cost 8 bucks, 6" diameter and works like a charm.
i just fix the tubing with zip ties and put some astrofoil (mylar-like) over it inside the zip ties.

you could also get a vase and crack the bottom off using a string and some nail polish remover. Just soak the string in the nail polish remover, put it around the place you wanna cut, light it up until its about to go off and put the thing in a cold water bath. It should crack it where you want it to crack. Someone around here did it and posted a vid on youtube.

I've paid my extra money on a cooltube from the hydro shop. 120 bucks on a 5" cooltube and a reflector. My 8 bucks candle holder works much better.

This is how you cut the bottom off! http://www.youtube.com/watch?v=Y9etHD9F90E I did this with a $10 piece of glass, but only after lots of practice on beer bottles first. The edge came out perfectly smooth, amazingly. That is me in the video

Thanks man! This was just something I did to avoid paying for a pyrex bake a round at the time, but to be honest, I often look for a good deal on them and am going to upgrade soon. Heat is not an issue, as I have a fan blowing air over mine, but I can clearly see that this glass does not let as much light through as a pyrex likely would. That actually requires a bit more research, I suppose

duke, using a cool tube lets you get the light much closer to the tops which makes for MUCH more light available for the plant.
Its not only about keeping the room temps at bay.
