Hey guys, could use a bit of help here if folk have the time,
Basically my extraction rig seems to suck, can't get temps below 30d so i think i've made a big design flaw somewhere,
Area is a 2.4m x 1.2 x 2m tent with 2 600w HPS's in 125mm aircooled reflectors, fan is a dual speed PrimaKlima (230/360m3/hour) linked to a standard 125mm budget filter
Carbon filter in far corner, fan, ducting bend, through both lights inline then through another 2.5m odd of bendy ducting

I already know the system isn't really right, i don't think your really supposed to run air cooled lights and a filter off the one fan, i can only assume due to the length of ducting needed and possible particle damage to the bulbs *shrug* but another inline is a bit out of my budget right now, plus the tent doesn't have 3 large vents for me to run the filter/fan plus an in/out for the lights
I also have a hunch the length of ducting im using and the amount of bends isn't really practical, theres obv a big loop after the fan and first light to allow the lights to raise and lower, 2m straight through the lights, then a similar loop at the other end, then it goes out the tent roof and down round the side and through a vent in a door which is another 2.5m odd, but with the current setup thats basically as short as it can be, but at the end you only get a faint gust of warm air, as opposed to a powerful blast off the 100mm ruck i tested the other day with just a filter and 1m of ducting
Bit of a ramble but I hope you followed, in summary, am i just being unrealistic expecting this one fan to push air through all this? its starting to look more and more stupid the more i type it out in black and white, i only upgraded to aircooleds recently and so far if anything they've made things worse, i can only assume due to this problem, the glass and the space under it do heat up a fair bit, if anything its radiating near the same as a naked bulb, is this simply because its not getting air pushed over it fast enough?
As far as i know i have access to a spare 200m fan, which of course doesn't fit the filter, ducting or lights...at all, a 100m toty inline from B&Q i planned to use as an active intake (didn't even dent it) and a somewhat dodgy 150mm cheap ruckclone, was thinking that bunging the 100m inline somewhere in the system might give it a bit more pull?
I'd obv prefer not to have to dismantle the entire system, but its looking more and more likely, any help or suggestions would be much appreciated, as i cant really commit plants to this area till its fixed :)
