H E L P !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!- I have an office cupboard that is 6ft high, 2.5ft wide and 1.5ft deep, after taking into account my fans and grow shelf my total growing space is 3ft high, 2.5ft wide and 1.5ft deep I bought a LUMATEK 400w hps with cooltube and already have an in-line fan (5" systemair in-line), and insulated ducting but thought mambe I could do a 600w instaed and promptly changed it for a 600w LUMATEK setup. BUT!!!!!!! temps were a little higher with the 400 but the 600 is mega hot like 55oC degrees and am having trouble cooling it, oh I have a small IKON filter on the end... should I A) change the fan to a faster slightly larger one? B) change the fan to a faster slightly larger one and get a bigger filter, or c) this is overkill for the space do steps A+B and keep my fingers crossed or d) change it back to a 400w hps and still upgrade the fan and filter PLEASE HELP ME ASAP ( as I need to sort this at the hydro shop tommoz asap) MANY MANY THANKS - STELTHY
