Going away for a few days, chances of fire at my grow?

Got a grow setup got 5 30w cfl's pointing down towards a plastic storage unit with my plants in the lid wedged at an angle with the fan in the space it doesnt cover blowing air against the lights and the crop.

IS it safe to have them on 24hrs a day with no fire risk?

The box is lined with mylar and the lid is lined with a windscreen reflector

Have they caught fire yet? I leave my HPS and CFL on their own for upto a week at a time without issue.

Any fire risk present will be a result of you, i.e. flammable materials lying around etc.

hmmm.. well I dont think theres anything close enough to cause a problem.

not caught fire yet lol

Only thing that worried me was the lid resting on top...

Whenever i get paranoid about fire, which i do, who wouldn't, i just check combustion temperatures for the materials i'm concerned about and that normally alleviates all of my worries
