Do you guys reckon the fan will be enough to pull air through the 125mm odor sock in an enclosure roughly 60x50x120cm? The fan is an Ezi air inline fan.. or should i go the 125mm fan?

EDIT: Ill be running 200W~ CFL in this cab..

http://maximumyield.com/article_sh_db.php?...p;issueVar=June The Digital Sun: Better Light for Better Results by Erik Biksa 2009-06-01 There has been quite a ripple in the world of hydroponics since the introduction of digital lighting systems, sometimes referred to as electronic lighting systems, since their appearance within the last decade or so. As with many emerging new technologies, some of the first generation units showed us lots of promise; and in some instances they delivered on those promises, in others reliability was an issue with a few wrinkles that needed to be ironed out.

OK, so I'm travelling a road involving CFLs but the 'technician' in me and the primary driving factor being to grow good mull has me looking into the various lighting options. Part of this is looking into the capabilities of lights, the main thing being 'useful lumens' or maybe 'PAR Watts'. The key being a question about 'SO OK what gives the best bang for buck'. Questions about heat also interest me because I'm working in confined space. I feel I have to do this m'self because I can find very little info about practical work in recent times along these lines. I'm probably going to upset some people by suggesting that they have closed their minds 10 years ago and are …

Hello all Os'ers I'm looking to start a grow in my cupboard, it is quite small in width, but I believe it will be plenty for the one plant I want to grow, the dimensions are 47cm Width 178cm Height 42 Depth (front to back) i was wondering in a small space like this and only growing one plant, would a 250w HPS suffice? or would the 400w still be the way to go, I have no issue with buying a 400w, it's just if I dont need it I dont want to put up more money than i need to spend. cheers in advance P.S What is better, white paint or panda film, mylar is out of my price range

I made sure I told em that in no way whatsoever was their to be anything hydroponic related on the boxes and the shipping invoice. Well, The boxes were fine, it was the invoice saying GROWLUSH WAREHOUSE on it. Anyway, I'm thinking to myself, thats not too bad, its only the invoice, I should be ok....... So, I stumble outa bed this morn about 8.30, open the front door to let the cat in, casually glance round rubbing the sleep from my eyes and who's sitting over the road.... in a marked car.... three of em.... LOOKING RIGHT AT ME! …
