Needs to be tempered glass. If it regular glass temps in the 150 range will shatter it or even easier if moisture or mist from sprays or watering touch it. It will be like a shrapnel spray of glass.

If you get glass just ask if its tempered lot of homedepots sell it and I know most hydro shops have the right glass.you might be able to add 1/4 plexiglass under the glass as protection

oh ok wiked as,well was talkin to a mate at work about how hot glass can get before it breaks,he reckons if its heated evenly it will be right,but if its in one spot (i.e mine will be) it will shatter cause it will try to expand or sum shit, but couldnt work out what temp it would handle,and yer would suck if it did shatter cause my girl is that sticky,the midgies cant get off it lol,fuk smoken glass :mrgreen: ......im still gona try it lol....... i rkn if ya put a half decent fan on there it may be ight
