Sure thing! can't see why not!.............there is several sizes of candle glass at walmart and other stores like K-mart (Martha Stewart section) I got my glass tube @ walmart for only $6.78 and my wife was at zellers and picked me up a small glass tube that would fit a 250w hps no problem,she picked up the small glass tube not knowing the 1000w HPS bulb is huge! lol but you know you got a good wife when she is out shopping around for her self and at the sametime keeping her eye open for things for my grow room lol....

but ya you could pick up a smaller glass tube to fit the 250 w hps bulb or you could use a big ass glass tube I used for my 1000w for the 250w still would serve the 250w hps bulb anyhow.....as for the mh bulb a small mh bulb could fit into the large glass tube I used, no problem,but now I have to go out and get a bigger glass tube for my 1000w mh sunmaster cool deluxe bulb! because the glass tube I used for my 1000w HPS bulb is too small at the entry point of the glass tube for the 1000w mh bulb.......but should go right over a smaller mh bulb no problem!..............so to your question yes /yes and yes! exact same principal of putting together a 1000w cool tube! as it would be for a 250w,or 400w,0r 600w bulbs..........................

I know where to get a bigger glass tube for my 1000w sunmaster mh bulb I'll probably pick that up tomorrow and post a pic of it here!..............to behonest if I really wanted to I could get a glass cutter at canadian tire and run the glass cutter around the glass tube I already have,just etch into the glass ever so slightly a couple of times and once thats done a couple of times tap the glass slightly and it result in a clean break! which then would allow the hump on the 1000W MH bulb to enter into the glass tube therefore fitting!....either way I'll get the job done........here are a few pics to show different size glass tubes the small one was the one my wife picked up for me lol...perfect for a 250w bulb for sure!....but for a mh bulb youl'l have to go wider with the tube!...........
Mellow Man Reviewed by Mellow Man on . Homemade 1000w cool tube! First off let me say! that I asked around this forum several months ago about cool tubes for lights,we all know how exspensive those cool tube's with fans can be!...............by the time you buy the hood with glass $200 then you have to buy the fan and the duct work another $160 or so,it can get exspensive and odds are you will have to order most of it through the mail,which has a shipping and handling rate of another $50 to $80 bucks depending on where you live!.........
