I can see them quite fine. Looks nice.
i am i the only one who cant see the pictures
nice set up mate... another way to reduce your temps might be to locate the ballast outside the tent
here is a pic of our most recent set up in the tent
That extractor fan should be sucking air at the roof where the hottest air is but you need to have ducting fixed to both ends of the extractor fan so if it leads into another room or attick put the fan in the other room or attick and just have the ducting sucking from the roof like so.
(here is one i made earlier )
LUDA.
oh ok i see what ur saying. makes complete sense. imma try to relocate it. or just might get another fan.
thanks for the tip!
That fan is fine just get it mounted on or above the roof if you can and lose the filter at the suction end as its less efficient at drawing air from the grow room. With a filter on the intake side you are reducing the air suction from the fan but if you are exhausting outdoors or to another room you can fit a filter but i have no filters on my fan's ducting ends.
Just ducting at both ends giving it maximum exhaust and intake air flow.
If you aint worried about the smell throw the filters away as they are not smell proof anyway.
thats not a filter at the end. its just a 6 to 4 inch connector. so dont have anything on the end where the fan is? just leave it open?
GROWFAQ.
How do I install a duct fan to operate most efficiently?
(principles of effective ventilation).
Many growers own fans powerful enough to move air of a city block in Manhattan, but has failed to install it properly, causing greater pressure reduction. This extra pressure drop is called the system effect or system dissipation, and can cause the fan to produce a smaller volume of air than indicated in the fan diagram.
The following factors must be considered in order to avoid system dissipation:
At the Inlet.
The distance to the nearest wall must be more than 0.75 the inlet's diameter.
The inlet duct's cross section must not be greater than 112% or less than 92% of the fan inlet.
The inlet duct's length must be at least 1 x the duct diameter.
The inlet duct must no have any obstacles to the air flow (dampers, branching or similar).
At the outlet.
The angle at the reduction of the duct cross-section must be less than 15 degrees
The angle at the enlargement of the duct cross-section must be less than 7 degrees
A straight length of at least 3x duct diameter is required after a duct fan.
Avoid 90 degree bends (use 45 degree)
Bends must be shaped so that they follow the air stream after the fan.
If the connections are different from this, there could be a greater pressure reduction.
Circular duct fans for example, are propulsive, pushing the air. And should be installed so that the long duct is after the fan itself.
thanks great info. appreciate it! i need to figure out how i would hang it that high in the tent. the walls are not strong obviously and that fan isnt exactly lite.
The first one is so exciting.. You will probably not have your best crop but you have to start somewhere. Next thng you know you will be dialed in and bored and wanting to try more complicated strains.
