I had access to the 3x3 table for free was never used or even drilled out, using 3/4" fittings and a 320ghp pump to fill the table. 4 12" airstones in a 35 gal res (rubbermaid tote) & will be adding a secondary 15 gal res for topping off. Was thinking of upping to a 600w light setup but i think it might be overkill for such a small area, and i think it may cause heat issues.
Nice setup
So a question.... Is 4 inch ducting able to move enough air to substantially cool a 400w light? could it cool a 600w?
I know that as long as u have a good enough air flow and low temps durring the lights on u can easyly cool that 400w light. The 600w does get real hot and could be a problem if the temp out side the op get hot for any reason. IMO
To answer ur ????? with a 4" duct line and at least 200cfm will cool the 400, so yes it will, easyly with the temp bing as low as 70 at all times.
The 600 w is another story and should use a 6" line with a cool tube with at least a 200cfm fan to cool the light. I think that if u step up the size of ur duct line u can easyly cool that light.
I have a 600w light with a 450cgm fan, out side temp 70-77, and my temps stay around 77-83 whitch is not bad since im in a 4x4 tent. If i where u i wood get the 600w since u have low temps out side the room but i wood up size the ducting to 6" and a 200cfm axial fan.IMO U dont need a big huge fan but just enough to push cool air thru the light an d ou the op in to the attic or out side the room. Make sure ur ducting to the light is in a closed loop so u dont raise the temp out side the room or in the grow space,
temps right outside the outside the op rarely go over 70 even in summer
That is a great ting if the temp never goes up or down. Hopefully up can get rid of the heat from the light to the attic or othere room. If u are sending the hot air to another room in ur house ur AC will be fighting the heat from the light. Ive my ligh dumping the hot air in another room and my AC has to fight it even in the winter.
I hope this helped even a lil cuz i just rambleing now cuz Im
I Love Wake 'n bake
Yes i wood get the 600w, ur plants will tank u later..........
