screwdababylon! and grow in stealth box like this

[Rumpleforeskin]

Very clean. I agree with your decision to go with two plants rather then four. You will get more yeild and better quality in the same abount of time. My grow space is about the same size as yours. I just reduced my grow from three to two about a year ago. I get the same amount but the quality is better.

I messed with intake fans a few years ago. On paper they look like a bonus. But if they are not matched perfect to your exhaust CFM, one of the fans will be a restriction or a "coaster". I bet you would get more air flow without that intake. I have been wrong before, this could be one of them times.

looks like a nice setup
i have one large room split in two with both having 600 watt hps lights
i have a total of 16 plants with 4 a month away 8 6weeks away and 4 7 weeks away
i working on the perpetual grow and we shall see how i do with it
the 4 closest are looking great and getting slightly frosty and going to really start looking good any day

yUP

and thats a sativa setup
id prefer to grow it instead of indicas when i get some expirience

[screwdababylon!]

can anyone help me PLZ? take a look at the first pics poster in that thread -- on the second one ull see my intake 10 cm hole & 12 cm intake fan 180 cubic meters/hour -- just remindin U - my exhaust 250 cubic meters/hour 10 cm fan !!!!!!AND THE COLD AIR IS COMING !!!OUT!!! OF THE INTAKE 10 CM HOLE!!!!! THAT DOESNT MAKE SCENCE FOR ME!!!! so im losing a lot of cooling power and my absolute odor containment is fucked up !!!!!!!! any ideas??? peace

I would ditch the intake fan and make both openings the same size. Then I would put a collector on your suction. This should act to increase the velocity of the air and give you more air flow.

Wow, that is one of the best I have seen so far.

----- 1 this is a heat isolation material - on one side its kind of soft plastic foam and on the other is this foil thing u see ------ 2 im starting to think that the big exhaust fan is broken or something - anyway i think ill take out the intake fan ant connect it to my filter box as a second exhaust fan - my setup allows me to do this ------ thanks for the feedback

peace

what kind of cabinet is that a Mills Pride? how loud is your fan? and what kind of seeds are those what do you mean sativa setup is that why your lights are so far away?

thats an IKEA cabinet 250 bucks ---- the 3 fans in there make almost no NOISE----- the sound can be compared to - 10 powerful PC coolers working together---- i mean its a setup alowing to grow trees 1.5 meters----- those i grow now is a skywalker and WW-----the lights is so far becouse it doesnt matter now ---- thay grow under a luminicent lights now -----becouse thay R just babys now peace

You really want a neg. pressure in the box,why dont you just check the fans operation or switch it with another of the same to see whats up?

[demiurge714]

wow that set up looks so clean i love it

[screwdababylon!]

the idea with 2 fans connected to 1 filter box sucks becouse they conflict somehow and the airflow doesnt increase--- the most important thing about ducting is the shape of the ducting chanels --- take a look at my cooltube --- i figured out that it works at 20 % power only becouse of the ducting shape --- i think each 90 turn = -20% of fan power ---- now im working on the solution (more powerful fan + less turns + bigger diameter of ducting) --- thanks for the feedbacks

hi

here we go with some more fresh pics

1 first of all i installed 2 times more powerful exhaust fan (500 CMH, 150 mm diameter)
and increased its ducting diameter

2 the cooltube had a shitty fan thats why i instelled a 180 CMH (125 mm diameter) fan at the cooltube RIGHT BEHIND THE BULB - so it can suck air and push it with maximum power all around the bulb (the cool tube is a bit warm now)

3 i had to change the shape of the cooltube ducting to make it more streight and now
the hot air is thrown upwards to the seeling (NOT BEHIND THE CABINET - BECOUSE ITS THE PLACE WHERE THE COLD AIR FOR MY GROWBOX IS TAKEN)

HERE IS A GOOD TIP:
DONT LET YOUR EXHAUST AIR MIX WITH THE COLD AIR
BECOUSE THE EXHAUST TEMPS CAN SCREW EVERYTHING

HERE IS ANOTHER GOOD TIP:
KEEP THE CABINET FAR ENOUGH FROM THE WALL
SO THE AIR CAN GET TO THE INTAKE HALLS

4 I also increased the cooltube ducting diameter
becouse when ducting bends it reduces the diameter

5 i boght a "humidity generator" and placed it near the cabinet
the wet air it produces is 4 degrees colder then the air in the room


the result:
temprature in the room 24
temprature in the growbox 27
YES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I DID IT!!!!!!!!!

IVE BEEN THROUGH A LOT OF SHIT WITH THIS ONE
and i think i can help some ppl now

the setup did looked very nice in the begining
but not not everything that glitters is gold

peace

what'd you use to line the walls?
Looks like that foil insulation stuff from lowes/home depot?
