Cheers man,
I 'am trying to keep noise minimal as well cos of nosey next door neighbours also the grow cupboard is in our bedroom and the loft is bog standard except wood panel flooring, so fan in the loft isnt out of the question but I would prefer to find another way
however the way the system is setup at the moment when the cooltubes big 6" fan is sucking the air out it is also helping the CPU fan pull air in, and when attempting to open the cupboards doors there is a good vacume , I am honestly contemplating changing my giant cooltube for a smaller air-cooled hood and that should allow less of a bend on the left sides insulated ducting, if that still doesn't work then I'll replace the Prima-Klima 6" fan for a really hardcore fan .. I'll have to do some research though as to keep noise output to a minimal! and then finally if still no success then I'll temperally drop the 600 and use a 400 or 250 until next time when I go crazy and build my Ultra Cabinet from scratch, (with this one I really just wanted to get experience and knowledge under my belt..as with HPS etc Am still learning... its very different to CFLs which in all honesty I had mastered! Well as you can see there is a lot of tweeking to do but I will get there in the end, I am not too concerned about cost cos I know in the long run I can make it back
but cooling these lamps is a fucker!! anyhow.. I bought some plastic number stickers and just mounted them in the 420 order on the Mylar.. the numbers had sticky backs so I just had to present them correctly, very nice and effective look I thought, still gotta plod on
