Use a drinking glass as a cooltube?

[manphredd]

Hi, i´m new here on icmag, and the micro growers forum. Seems very nice. Good source of info. I want to ask you guys something.

Today i had an idea when i flipped through the pages in the pc growers section here on icmag. I have been thinking lately that i would going to buy a 70 w HPS, and with the ventilation i got now doesn´t hold for that.
So i thought i could use a drinking glass to cover the bulb as some kind of cooltube.
I don´t know if someone has ever done this before. I saw something that looked like it. That´s how i came up with it.

My question is if this would work? I won´t push air through, it will just pull air out of the glass.

Maybe i could use something else then a glass. Maybe plexiglass, or a regular ½ liter plastic coke bottle or something.

Feedback is appreciated

Look for hurricane lamp replacement glass. Should be thin enough and wide enough for a 70w.

There are also some wide glass tubes that are made for placing on bases around candles... look in the places that high end candles are sold or the materials for them like an arts and crafts shop. (Dick Blick?)

There's also online?? Custom Pyrex Glass Tubes

Stay Safe!

Thanx mate. I apprecieate taking your time. I think i will persue this idea. Maybe not in the near future as i first planned, but in these next couple of months i am going to try to get a hold of some cash so i can get the stuff that i need in order to make it happen.

/H.

for that you've gotta get into glass cutting. I was on youtube the other night and found some vids on cutting wine bottles in half

theres a specific tool that's used and is pretty nifty, theres also vids on how to cut the glass with string. . . I know it sounds off but go look at the vids and youll understand, it makes a rough cut but as long as you can keep that string straight around whatever your cutting, you can get a good enough cut to use something as a cooltube.

I would suggest you get a bake-a-round tube, but ive been searching for one of them for so long im starting to think that its a myth and a lot of folks on here like to assume that just because an item is stocked at their local walmart/store that it should be stocked at yours too and its simply never the case. certain things they sell in certain areas and that's that.

you'll find something to use though. put on your "grow room goggles" and go looking in your local homegoods of tjamxx type of stores where they sell that sort of candle tube or really tall vases. I saw a vase in micheals one day that was 2' tall and 8" around for $15. I tell you no lie when I say I literally started to drool in the store right infront of it. alas no money at the time.

that's my advice for anything for growroom construction, get your "grow room goggles" on and go hunting around in those types of stores. bongs/pipes/grow room stuff/incense burners trust me its all there in one way or another

don't look at thing for what they are, look at them for what they can be

I actually had one... bought it off of e-bay... never got a chance to use it. *sigh*

I'm seeing one Pyrex Bake A Round tube (used) at amazon for $20 shipped. Plus several at ebay.

If you have a Michael's or craft store nearby they have plenty of glass tubes. The Pyrex ones are nice because they're acrylic I think.

no theyre not acrylic. pyrex is soda lime glass. unfortunately most people think its borosilicate.

Pyrex bakeware made by World Kitchen is soda lime tempered. Pyrex by corning is claimed to be all boro even the bakeware and measuring cups.

All pyrex[corning] tubing/labware is boro and so is the bake-a-round.

Today i had an idea when i flipped through the pages in the pc growers section here on icmag. I have been thinking lately that i would going to buy a 70 w HPS, and with the ventilation i got now doesn´t hold for that.

Couple of years ago I scored some clear boro tubing that was random lengths but was 8" diameter.Each piece was over 58 inches long. This was off of Ebay for less than $100. Bake-a-rounds are all over Ebay and Amazon, just looked.

Look up tubing supply companies or labware wholesalers, they might sell broken pieces that you can cut to length. Glass suppliers for bongs, etc.
Hurricane glass is out there, I just lost interest in it. Especially with big pieces of clear boro tubing out there. Find a glassblower and try to be friends

Is it a 64 year old bake around tube? Or is that 1 piece excluded?

Bake-a-rounds are one piece antiques. Both ends are open. What 1 piece could be excluded ?

Only problem with bake-a-rounds is the fact that they are indeed antiques, meaning scratches (etc.) are damn near guaranteed. You be better off with ordering from the link posted up top to the custom pyrex tubes as they are brand new.

Yes im aware they are antiques as i stated in an earlier post. The 1 piece im asking about would be the tube. If you read my post, which contains an excerpt from the pyrex website, it clearly states;

"Pyrex glass bakeware has been made – first by Corning Incorporated and now by World Kitchen – using the same soda lime composition and heat-strengthening process for more than 60 years."

So again, if all pyrex bakeware is made of soda lime, and not boro, the claim that the pyrex bake around tubes are boro would be dead wrong. Thats y i asked if that 1 piece was excluded from being soda lime like pyrex says ALL of their bakeware is.

i got to hit a punch for torches for candles! gonnah give you a link http://www.google.se/imgres?imgurl=...bnw=130&ei=BM31UKetLYfp0QHLxYGADw&um=1&itbs=1

 

[ericforeman]

good for up to 100 w hps

I don't know if we are allowed to post links here, so I won't, but just go to ebay and type 250 HPS COOL TUBE METAL HALIDE +400 + SOCKET EXTERNAL WING REFLECTOR COOLTUBE into the search field.

If I were you, I would just buy one of those. It's 5" diameter and 12" long. I bought one expecting to use it for a 250w before I received it and realized it's slightly too short for a 250w bulb. But the 150's would fit in there perfectly!!! $40 and it already has the socket and cord and everything else you would need, minus the 5" ducting (or duct reducers, etc.).
