Aloha,
So Ive finally finished up my first cab. She's ugly and an obvious eye sore but it looks promising to me. Also, dosent need to be ninja stealth, but I cant have ducting running every which way. Test running with cherry tomatoes, habaneros, and jalapeños. I know all require different light cycles but its all for testing cab temp and noise level.
Cab dimensions: DxWxH - 1.7ft x 2.7ft x 5.5ft = 25ish ft3. x 3 (refresh rate) = 75cfm, base.
Add 5% for light heat (3.75cfm), 50% for summer heat+humidity (when it comes, 37.5cfm), and 40% for scrubber (30).
CFM needed for cab = 146ish.
But ignoring all that info, Im simply doing temp/noise checks right now.
Passive intake with 2 Tupperware boxes stacked, taped, and holed. No light leaks as i checked thoroughly. Passive intake size is the diameter of a CD-rom. Traced it onto the wall and crudely cut it out.
Full spec led panel, 180 true watts. (doors closed, no fans, temps get to about 35c..... I dont know if thats normal for a LED grow light or not... input welcomed)
Exhaust fan - Scythe Kaze 3000rpm hooked to ac-dc adapter
ghetto ass ducting- black felt glued onto windshield sun blocker thing, then rolled twice.
Fan is fastened inline via zip ties
Ducting is fastened to a pvc elbow (zip ties) which is hella tapped to my exhaust hole.
The whole thing is held up via bunji cords BUT because the pvc is touching the cab, the vibration from the fan is also transmitting its vibration -_-.... gotta fix that somehow. Probably another set of ghetto duct.
Exhaust hole is the same diameter as a CD rom (same size as intake)
I have light leaks from the doors but Im unsuccessfully trying to fix it... latest attempt is a thin piece of foam weather stripping taped to the center strip of black duct tape. The strip covers the crack between door and wall while the tape holds it in place. It seems to work, except every time I open the door the tape looses a little more of its adhesiveness =|
***PROBLEMS:*** NEED HELP
Temperature.
Ambient room temp is about 26c (actually lowered when left thermometer out longer to about 24c), and inside the cab it gets about 30c. Exhaust temps are about 29-30c.
Because its a test run and Im not having to worry about MJs stank, there is no filter obstructing the kaze from pulling its listed 133cfm.
What can I do to drop this cab temp to the recommended 26c without running ducts everywhere outside the cab?
I have 1 more kaze fan, same type, Im not using. Will throwing that in reduce temps any?
NEXT ***
Duct Connection.
I know I went DIY with the duct so its my own fault but does anyone know how to connect ducting to a flat surface?
I attached the pic of what my filter is. It goes in the sink to catch food stuffs. The holes aren't huge but it doesn't seem to restrict any airflow from the exhaust. I checked the fans breeze before throwing it in the cab and it feels the same.
Thank you everyone for looking at my 1st cab. I appreciate all comments and/or advice you can give.
I know a grow tent would be easier but I got this cab for free so Id rather use the tent money on a good fan when the money comes in.
Ill be lurking / bumping.
