    ive got 4 80mm psu fans all connected up together in a row using the 3pin - 4 pin molex (4 of em) then got a 240v-12v cctv adapter joined at one of the ends of the molex'es all seems to work fine, didnt have it on for too long but i didnt think it would be a safety concern, think ill bring my box into the front room 2moz and leave them on all day, but tbh as long as you have the correct parts (the ones monkeyboi showed us) with all the correct ratings surely there wont be a problem?

    New placement for fan. Lobbed some holes in the back of wardobe and a square chunk for now (will expand if needed). I found some old speaker wire very thin but should do the job it works i just hope its rated for 12v i think it should tho i aint a expert. Hopefully this will cool things down somewhat. Already felt lots of warm air coming out the back.
    Everything that i say is a work of fiction i.e made up, this forum is full of fiction i.e made up stories. All pics are found on the internet to show a visual identification to go with our stories we write for fun.

    No need. If your intake is bottom-oriented and outtake top-oriented you're fine with any lighting setup, honestly. If you use HPS, expect a drop in yield, if you use MH expect a similar yield with my LED panels for the *SAME* room using 30% of the power of the 1000w MH bulbs. Proven with NASA.

    Enjoy. Do your research, please.

    when i put the thermometer facing the bulb it gets to 40c but when i place the thermometer vertical against the plant it goes to 33c which is still too hot..I have got a inline fan sucking air through the filter and a large standing up fan on full blast blowing at the bulb and now this pc fan which is sucking air out and its only a 400w hps

    i have the flaps open as well but nothing more really I can do..in the shade it only says 26c near the plants but when in full direct light it goes to 40c..anyway,there is really no hint they are stressing apart from a few leaves turning yellow,think thats down to me using too much nutes anyway,but not going to get autos again,too damn feking small..the 2 in my tent only got about 3 weeks or so to finish,may add a week to it but have just put 2 fem lemon stinkys in the tent that was in my closet..got 2 more autos from the same batch of seeds in my closet with a 300w cfl,doing ok..think one is male so pulled its feking bollocks off,how dare this plant grew balls lol..
