DIY cool tube made from 2L glass beer bottle

o.p. What size bulb are you using? Will this work for a 400 watt HPS?

Just make sure that the tape and all the materials you use can handle the heat of a 400w bulb, but definatly.

You want that, you need either a liquor bottle (3.75L), or a large Jaritos bottle (4L) and do the same thing...and monitor it for the first few days as it is untested...

Actually you have to be very precious on rolling the string. you must roll it in very tight line then the cut will be more precious. I had quite uneven top cut and there has appeared crack in one place. So the idea is straighter the cut - more durable the cool tube.

That is a great way to cut glass, plus rep to you! I have been looking at different methods of cutting the bottom off a glass jar I have and couldn't figure out the easiest way, but this lighting the thread is so simple I was trying to score it and all with a stain glass cutter. Great job!

I have been wanting to post some of my DIY stuff cause I too am also all about the Macgivering, but have been to paranoid to post pics on here especially with the photo meta data and serial numbers attached to the pics. I wouldn't want to have to get rid of my only camera for whatever reason, but great job on the project as a whole.

if you want to make a DIY cooltube with a bigger light.. (up to 600w hps) you can buy a pyrex bread baking tube on ebay for $10-20. no glass cutting required

Love the light, I'm kicking a 600w. cool tube in a 2x3x4' area and thought I was just about on par.
Thoughts?

You can buy disposable digital cameras for between $12. and $20. that would work great for this!

All you have to do is load the picture up into MS paint...save it as a BMP, then save it back as a jpg and all the information gets stripped out of it

Lol this is true so that is why I tried the slight scoring of the glass with the hot water /cold water treatment and worked great, I am now the proud owner of a glass tube .

You can go buy a bake round tube for 20$ or less, but I just got my tube for 2$ from the dollar store. Besides Macgiver didn't always have a store nearby supplying paperclips and bubble gum, he would never cave into just buying a tube, he'd be ashamed lol now get out there and Macgiver shit!! not go out a buy what you need that's just not exciting lol

i run a 600w in a 4x3x5 and its fine your space might be more suited for a 400w but if you're on top of your temps than i dont see why not.

if you're unsure of what your temps are gonna be like i'd opt for the 400w. just my opinion based on my experience

 

[smokey de bear]

Do you run your cool tube ventilation separate or inline with your room exhaust? This is what i'm debating right now
