Vertical aero racks

Hi Dirthawker.
that looks amazing,

1, do you think the plants can be set up like this growing in soil too.
2, is this a great way to save on space or does conventional growing just save the same space.
3, when the lamps are hanging like this is there any risk of say bulb explosion or fire, as i had a sealed metal unit go on fire last year inside and i noticed that at the screw end of the bulb when i took the toughened glass screen off to inspect it that the connection at the very end of the bulb the solder part in the middle was totally melted and the connecting wires to the holder were all burned totally black and crispy, but with me having a sealed room with internal and external 8" fans it just extracted any smoke outside when i was not in. when i returned the lamp was off and thats when i noticed the burning inside it when i went to change the bulb.
i changed the bulb and wiring and the same thing happened to the second bulb and wiring so i dont know if the ballast is making it too hot or if it is the bulb holder/connector that was damaged.
but what would have happened in the case of the bulb and holder being in the open air instead of inside the steel unit.

thats a pretty sweet set up i think you may have inspired me to make a mini version out of coffee cans( i think i will do, 30 sites 1/4hp pump, gonna be tuff figuring out how to make the rack to hold everything) can on a side wall in my tent in addition to my horizontal plants.

thats a well designed fairly affordable system. doesnt get much better than that
