Handy little cab ya got there. Are you going to paint it/line it for light reflection. You could get two 50-80L plastic bins and stack them on top of eachother? they are like 15 dollars each.. would be taller give you more room for flowering? Then you could have a veg and flowering "room" lol good on ya for growing man.. it's soo much fun!! What lights did you have in mind?
