Hey Chongman,
I have a 6" Suncort duct fan sucking air across the light and pushing it out the left side of the box, which is always on when the light is. I also have an active input/output vent system I run to maintain the environment in the box.. Currently running at 72-78 deg, 50-70% humidity, with the box sitting in a garage getting into the low 30s.
You building something similar?
Peace, Farmer Rich
Yea i got one cab for veg and another for flowering. Im trying to get ideas for ventilation in my flowering cab. I have a 400hps lamp in it hooked to a 140cfm dayton blower sucking the air out of the reflector. I dont have an inlet to the reflector its just sucking the cab air. Im looking at your cab pics and Im really impressed! I vote it grow cab of 2007! :thumbsup:
I second that movement. It definitely gets my vote. :thumbsup:Quote:

How long did it take you to build that grow cab?
Glad you like the cabinet! It ended up taking about 4 weeks to build but I gotta tell you, I get a little focused on projects like this one. So far I'm pleased with how it's working, though I was starting to worry that I over ventilated because I was drawing the humidity down to the 15% range. Currently (winter) I'm running one (of 2) exhaust fans and have the main input blower (160 cfm) running with the duct boosters off. The CAP AIR-3DN is keeping everything dialed in just perfect. I also added a small cold water mister to increase the humidity.. When I go to flower, I have a small electric heater I'll sit in the box to maintain nighttime temps. If you want more pics or anything on it let me know. I'm thinking I need a second box for dedicated veg..

I really think you should do a full construction guide for that cabinet. I think it's absolutely amazing.
I do have a couple of questions though... What is that piece of split ducting doing on the top of the cabinet? Also, what is that box and is it connected to the ducting?

P.S. You can't add images to your posts until 50 posts I believe. That's why I did my first "grow log" in the Indoor Growing section. ;)
Im not sure Norkali, but i think the ducting goes to another bathroom exhaust vent in the opposite corner. As far as the silver box in the middle is probably the ballast for the light. I looked at those photos at least 50 times in the last month! Truly an inspiration to cabinet growers! Keep up the good work Rich! :)
Possibly, I know the box in the middle is the ballast, I've got the same one. Digital Greenhouse 600w digital. :thumbsup:
I'm asking about the box on the left. :stoned:
The box on the left is another 50cfm bathroom exhaust vent he has 2 of them on top, one on each side of the ballast
Thanks again on the box, it seems to be rockin'. Today is day 1 of week 6. 4 plants - 5 weeks, and 5 plants - 4 weeks old (all from bag seed). So far it's looking like 3 sativa, and 1 indica from the first batch. All of the ones from the last batch have really broad leaves and look afghani to me.. but hey, I'm a noob and don't know squat.. learning fast though!
Ok - Ventilation; Exhaust - 2 x 50 cfm bathroom fans, with individual switches to disable/enable as necessary. That's what you're looking at on top. Input - 160 cfm eco fan (also on top) pumps air to the T at the bottom of the main grow chamber, each side of the T has a 4" Suncort duct booster pointing to the two inputs. The box is going to vented to the outside, but I'm waiting for some electrical work (18kw generator ;)) to be done before cutting the holes in the wall. I'm also going to have to use another 2x4 to add a spot to circ clamp the fan in order to raise the light to full height.
The light has a 6" suncort duct fan on the left side. It fit perfect into the 6-4" reducer. I used the reducers on either side and just capped them with vented covers on the back to keep any critters out.
I have a CAP AIR-3DN in the top which controls the intake/exhaust systems using day temp. During lighting < 24 hours, I'm going to plug a small heater in to maintain night temp. I may have to figure out some sort of shelf due to the 9 plants taking up so much room. I'm a little worried about it being too close to a pot and over heating the roots. There's only about 38 cu ft, plus the shiny material inside the box is duct wrap I put in for insulation.
I will make it a point to upload some frame pictures. I'd intended to document the build, but just ended up doing it..
Okay.. since we're supposed to be talking about growing here, I'll upload some plant pics a little later and you guys can critique the progress.. :jointsmile:
Later, Farmer Rich
