No problem bro
Ill look around .. Ide say it wouldnt be too hard to find..
Just make sure the glass is a few inches wider than the bulb so theres suffiecent air movement to keep it cool.
Ide check out a few places .. Bunnings/Hardware stores .. possibly Kmart and Copperart . .
Just ask for Tempered Glass .. That can handle hot temperatures
Lamp glass covers would work too ..
The glass would be the hardest piece to get - Everything else u can get from a hardware store ..
And within 30-45mins it would be completed
If i can find suitable glass im going to make one and put a 1000watter in my box
Aslong as u have cool air getting sucked from outside through the glass and back outside .. you could have a few 1000w in a small space and have no heat problems at all, cause the heat wont be going into the box or where your growing .. but rather straight outside
This opens up small-space growers to MASSIVE BUD potentials if done right
