question, how great is the difference between insulated ducting and the aluminum ducting? there is quite a big difference in price. I just wonder how worth it is. Maybe not for my spare bedroom grow but at least for future reference. See alot of people on YouTube use just normal ducting. I can imagine the ducting for the hood has some warm air going threw it, it could be escaping into the room on the way out?

Hey wheels i tried to msg you but your full, just wanted to thank you for all your help. Question, if i want to do a passive setup. how do i setup a passive intake if im using an ac so that the ac isnt always running. It seems like all the air im cooling would be getting sucked out threw the ducting going outside threw the carbon filter? Is that just how it has to be or is there something i missing?

well your trying to eliminate two problems at the same time. the heat from the bulb and the heat from the room. ultimately making the ac work 10 times harder the way you have it setup. the ideal way to setup your room would be to closed loop the lights and have a single fan on a timer sucking the wasted air out of the room once every hour for about 5 minutes or so. that way the room stays somewhat sealed and cool. can i ask you this? do you have free open space in the window? or does the ac take up the whole space? can you fit another 6 inch hole somewhere into the window with the ac if you sealed and mounted the ac with plywood instead? kind like you did the floor for the exhaust with the metal grommet? sorry the inboxes suck on here. lol. its always full. a lot of people needing help with stuff. sometimes its hard to keep track of deleting them.

ya the window unit doesnt take up the whole window so there is plywood sealing the space and securing the window unit from break ins. As for putting a a whole in the plywood its at the front of the house and would look even more suspicious. I dont have timers or speed controllers for my fans...
I guess this was just a poorly planned grow op, ill finish it out and move it to a back room or start working on my building during the summer for the next grow op when summer rolls threw.

I dont want to butcher the floor with 2 more holes, i like the closed loop idea for the lights,maybe once im done with the plants i have going ill try in the back room which has 2 windows i can modify for ventilation that wont be able to be seen from the street..

you wouldnt need to butcher the floor. and to be honest it would be sucking air in from the window and not blowing. so you wont have any heat coming from the front of your house or smell for that matter. it would draw fresh air in from the window thru the lights thru a fan then thru the existing hole in the floor. it wouldnt be loud since the fan you would be using would be at the floor end. also who really knows why a hole is in the plywood. and do you really think people will care and take a look? if so 86 the idea. ill keep thinking. ill come up with something that should work for you. also the fan would only be on cooling the lights when the lights are on.

how hot were your temps when you have the ac going and just the lights with no exhaust?or have you tried with the 2 lights going and ac with no exhaust? try to vent the hood just into the room with the 6 inch fan so it has passive airflow for the tent which cools the air a bit while it pulls it. cover the exhaust hole and vent the tent into the room instead of out the floor. see what your temps add up to? your ac will still run all the time it should just be a lot more effective and hopefully wont kick on as much. hopefully the temps stay decent. the hole in the floor was not a waste my friend becuz if the temps stay ok the hole will be used for exhaust once an hour for 5 min or so. u will need a timer. but they are relatively cheap at walmart.

ordered me a 45 pint dehumidifier with pump out, for future use. Im sure it will come in handy for my year round grow!

Also took some advice and turned off the 400 mh that i was using for veg and put my komee sun god 125w duel spectrum cfl for the veg area to reduce heat. Going to go ahead and order 2 more air cooled hood for the remaining 400w ballast.

As soon as i get the 3 girl done flowering another 30-45 days and ill do some major remodeling.

sounds good. sorry the major remodeling gonna occur. but once its done you shouldnt have to worry about a thing that has to do with temps once its all hooked up. doing things right the first time is always better to do than piecing it together as you go. i did that with my first grow setup and to be honest it was a freakin nightmare. always having to stress out about something temps, humidity, light leaks, and pests since it was a shed i built outside specifically for that purpose. also having to find the funds to take care of the problem sucks. lol. but you shouldnt have to worry about that if you do it up right the first time.

also buying things before you need them is smart. i should have baught a 35000 btu ac before the move to the new spot but money and power is an issue. gotta get an electrician to bring in a new 50 amp 220 outlet first. becuz having the ac and being able to power it are two different things.

that brings me to my next question. how much available power do you have to your op?

i have popped a 15 amp breaker a few times when everything was on the same breaker. Using an extension cord on the 400w and it stopped. Figure it would be better to put a light on an extension on the light and not the ac.
I have 3 ballast 2 400w and 1 600
i want to get all threw running but i dont think that will be possible in the room right now.
will have to think about that when i build my grow shed.
so i want to get 2 air cooled hoods in the flowering and veg with a few cfls.

trying to find the best way to do the passive intake.

I am going to put 2 more holes in the floor, one in the closet and one on the other side of the room from where i put the other. Going to cool my lights with a closed loop with the cooler air from under my house. pushing it out into the open, then i want to run the carbon filter out the other hole in the closet and vented out threw the skirting of my house.

Just dont know if those booster fan are enough for the carbon filter...
still got to get some digital timers that i can set up for 5mins an hour for exhaust
got to put the inline fan on a timer that goes off with the light.
and fan controllers
lots of addition tweeks and accessory's im going to need anyway.

i just dont know if im going to build a new grow tent with 2x2s and panda film or if im just going to keep the 4x4x8 grow tent, sorry i purchased it cause they are not light tight and have cause nothing but problems keeping light out while vegging in the same room.

i cant find any passive intake videos that i like. Just need to find out how long it will take to get my building going so i know if im just wasting my time just to start over. If i grow for like a year in the room it will be worth it in my book.

question can i skip the 3rd hole in the closet by putting a T at the exhuast and add the carbon filter to the T
Example

Floor intake to light then another light then 440cfm fan to T and out threw the floor, Then put the carbon filter at the top of the room and put the 2 240 cfm booster fans in ducting to the T, will these booster fans cause enough suction to cause negative pressure for passive intake?

Or will the t cause constant suction on the carbon filter, even when the booster fans arent running.
Will i need the two booster fans on a timer or since they arent very good leave them running?

Attitude delivered, i went to pick up my souvenir's today from the po box and it was super stealthy. Really like the shirt!!
USPS tracking followed it all the way to my po box and I am super satisfied with my purchase :)
Probably going to start with the mystery mix and a auto cheese candy.

i think a y might work better for your situation. a y has less of a chance to suck the air out without the fans on and without blowing the hot air back thru the filter.

also i order a shirt with every order. i love all the ones they send plus they guarantee shipping that way.

well right now i have a 1 600 on a room outlet,with all the fans the ac and any other gadgets pumps ext. the one 400 on 25ft extention cord, decent gauge cord. Havent tripped a breaker since and the cord doesnt get warm at all no signs of burning on either end. I think the ac is what pops the breaker when the compressor kicks on and off.

Ya i really liked the shit, definitely going to use them again down the road.
