where did you get those computer fans from?

Hi Stilzz,

Got my computer fans from my local computer shop.
They are fans pulled from dismantelled computers.
going to get 3 more this weekend. Only £3 each so nice and cheap.
going to make a box for my light ballast with the fans keeping it cool and
also going to hook the box upto the exhust duct.
The ballast is heating my grow room up to much and messing up my temps
so going to vent all that heat out of there.
my computer shop just has a box full these fans so it was a good find

ive heard a lot of good things about flying dutchman.. looks like you have some great things to play with.. good luck .. + rep posted..

Cool,
I am working right along with you. I have one of the larger tents and I just started running a 400mh on them and noticed it got pretty warm with no ventilation. I am going to check again to see if the temp leveled off or if it keeps rising. I have a g force still sprouting, a White Diesel Fem and about to dew a few Afghan Kush. If you ran the CFMs inside the tent and had one on the light and the other on the scrubber and you had the larger tent running a 1000hps with the ballast outside the tent do you think that will be all I need for the heat issue? Or do you think I should run a third fan pulling air inside like your PC fans? My setup really would not have any hot items in the tent. I also plan to run a 437cfm through my light The scrubber I think is about 250cfm?

Thanks

My tent is in a room which is about twice the size of the tent so it gets really warm in there
when it is all on. the light ballast is outside my tent but in the same room and after a few hours
it quickly warms the room up. The computer fans are pully a good amount of air into the tent but
once the whole room gets warm they are only pulling in warm air.

I am going to transplant my plants on saturday into there larger 11 litre pots and hook up the auto
feeder. Im also going to vent the heat from the light ballast through the exhaust duct to further cool the room.

I have a vibration free silent running water pump coming on friday and also 10 metres of insulated 5" duct.
this should help get rid of whats left of the inline fan noise vibration coming down the shitty standard 5" duct.
I am also going to run 2 lenths of duct from the bottom of my window in the room connected to the 2 fans
at the bottom of my tent to bring fresh cool air into the tent. all hot air will be vented up into the loft space
which is heavily insulated so will keep the whole room nice and cool. This should all be done by saturday night
and then will soon move upto the 400w MH lamp on 18 on 6 off probably in a weeks time. Im just running the 250w MH
for now till the transplant is finished and to build them upto the 400w lamp so I dont shock em too much.

There are only 9 left from the 13 seeds now. some of them didnt make it but I only need 8 of em so its worked out nicely.
Its nice and cool outside now its around 11c/51f so my temps should balance out to around 26-27c/80f so will be a nice temp to grow at
if it all works.

My last resort would be to buy a cool tube for around £50 and connect that upto the exhaust duct as well. but when it comes to flower
I would need to get another carbon filter for the loft due to the cool tube not first venting through the carbon filter in the tent. keep the smells down!

smells wont rise away as quick as the air is getting cooler around here at night. I recon when it comes to flower the temp outside will be around -1 to 3c/30 to 37f so need to eliminate as much smell as possible. a carbon filter at each end of the exhaust system should do the trick.

also another problem is my flat gets very cold in the winter so they will probably need a heater on in that room on the 12 off cycle. my temps will be ok when the lights on though. will have the 600w HPS on by then. that is still at least a month away though.

Just want to make sure I get my set up right for very good ventilation and tempreture control without making alot of noise or smells. there is a night heater in the grow room right next to the tent which comes on at midnight and goes off at 7 in the morning and then stays warm till about mid day which is perfect timing as i want them to sleep at night during flower.

so temps should work out very well during each switch over. my window in the room is only open about 5mm but will draw in a good amount of cool air during the day when the HPS is on keeping the tent cool. my first harvest is planned for the christmas holiday so its going to be a very merry christmas for me this year if my grow goes smooth after the final tweeks this weekend.

Infact im just going to get a cool tube as well. pay day next week so will have enough for all the extra kit.

iv already spent about a £850 on this set up and it will be about £950 after the weekend is out and then about
£1100 after the next 2 weeks and hopefully it will be done for at least this first and a second grow.

im hoping to make my money back on the kit after the first grow off 8 plants and then second grow make a little profit to help pay bills and shit.

just see how it goes.

Any way thats just a little background on my grow situation.

This is my first and I want to make it as best if possible so I can run it for a few years undetected. lol I plan on 4 to 5 harvests a year. 8 plants on every grow. aiming for at least 2 ounce a plant.

any way im mega stoned right now. Iv just finish my £10 bag of weed and iv been typing for what seems a long time.

some more pics on the further improved set up will follow probably on sunday. the girls are about 6 inches tall now. I will gets some pics up of them transplanted into the auto feeder as well.

right im off to go play war games on my 360 for a bit

take it easy stilzz

so iv got some more stuff turning up tomorrow. Got 10 metres on insulated duct. One vibration free silent running water pump. one silent running air pump with some air tubing and an air stone for the bottom of the res under the pots.

Iv also got a heat shield up to 600W to go under the light so I can have it closer to my plants after the transplant this saturday and another timer switch for the water pump in the res for the auto feeder.

got a nice wooden box im going to cut 4 holes into. 3 for the 3 120mm computer fans im getting on saturday and one for the exhaust duct. My light ballast will live in this box and should keep it nice and cool!

your creating your very own russian space station..

lol. Thats the plan.
See but not be seen!
Iv spent a £1000 in a week on this set up.
should finaly be complete by saturday lunch time

yeah this stuff can be pricey.. security is worth every penny. keep a couple steps ahead of the rest.
