Saftey For SpaceBucket

Hi this is my first post and im very much a beginner to pot (only smoked around 20 times) and already getting ready to build a space bucket! My question right now is just how nothing bad can happen to it.. such as it catching on fire or electrical problems and so on. If any pros can help give me some tips i would very much appreciate it thank you!

What the hells a space bucket?

its a grow room made out of 5 gal buckets that house one plant and use a UFO light. heres the link for the build
