Everything is up to code, I'm using GFCI and high quality electrical components and wiring. Every connection is soldered and heat shrink shielded. Safety first bucketeers! For airflow I have 120mm fans, two intake two exhaust. Working on light traps, I've got dust screens on the intakes. My lighting is a 135w UFO LED light and 4 CFL bulbs (cool). Also using a 5630SMD LED strip for flower (warm). Should be able to get them nice and big with this setup!
