Insulated ducting ? Heat and sound problems ! !

[puckuck]

4' x 2' x 5' tent
400 w DIMMABLE cool tube 6''
160 cfm 4" inline fan
LOOK AT PIC

so I'm not growing any cucumbers right now, but I tested my gardens environment, and after 45 minutes in a closed tent, the temp rose from 76 F to 85 F. The fan is also quite loud because the garden is in my 4' x 5' x 10' walk-in closet, connected to my room. The exhaust is just going to the outside of the tent, into the sealed closet.

A lot of the time, this won't be an issue as long as I keep the closet door open and open the window.
But every now and then, if I need to close the closet, I can't risk that temp going past 85 F if I left it closed for 6 hours or more.

So, researching on duct, I came across insulated ducting.
HMMM.....thought I.

So I researched it, and I saw someone comment that the insulation in the ducting would actually absorb the HEAT and the SOUND??

What's your input on this,
and how can I fight the Cali summer?

i have a 1mx1mx2m tent with a 600 w cooltube .i to was haveing heat problems was advised to buy.a bigger fan of some guys on here.so bought a 6inch rhino filter fan.no more heat problems.mine is set up like this carbon filter-fan-cooltube-ducting to out side tent. the fan is a little noisy thats my next thing to fix.

if you cover where say's (other side of y open ) you should have a better flow through the cool tube so their should be less heat from bulb that should help some at least

I also think you should vent outside of the closet your tent is in

Simple 5000BTU A.C. my friend placd in pan on floor and set it and forget it condensation is little and work's...little work to attach to your passive vent...then add Co2 and watch yiels' soar..never realized the damage froom heat stress.....It was almost 100 degrees my plant's never knew 77 degree's allway's (unless I want lower!) see result's....had issue's with 420cfm on cooltube only remove's 90% of heat but does nothing when ambient temp's hit 100...fan's only remove heat no cooling! same size grow mounted ac in tent for friend and yield doubled! this ghetto grow work's the proof's in the pudding! yield last grow same pheno yielded 33 oz's in 16 sq ft! avg 4-6 main cola's per planr avd weight dried each 4+oz's...Run duct w/fan to vent heat from ac outside if necessary...I have no need! insulated best and get speed controll to get rid of noise from fan!basment smells awesome but use inlet filter on light so no smell's exit house! only last three weeks.totally automatic grow sometime's a week between visit's...have verry ill wife and spend much time at hospital...Has to work! have temp power shut off and smoke and fire alarm's mounted...small camer's outside of grow and inside so I can check on line! and make sure nothing is going on..has infrared so 24/7 like me...Plan Plan Plan! go over every senario!

I wish it were that easy, but that's not an option when I'm under high-stealth, hence the closet is boxed-in.

Remove your adapter, put an axial fan at the end of your tube and duct it.

Or

Buy an additional duct, connect it to your passive intake and into the other side of your Y adapter.

What would recycling the already-hot air do to pass through the tent again?

I like your thinking, but unfortunately running ducting off an AC into the closet is not an option when I'm under high stealth, but I will definitely consider getting an AC to cool the exterior bedroom.

Whats a good way to add Co2 to the room? Can I run it through the ducting?

Amazing yield, I hope mine will be as successive.

I hope your wife recovers man, sorry to hear. Keep her medicated!

Thanks for the input everyone, but I haven't had much feedback on the actual topic of the insulated ducting (with the insulation fuzzy stuff inside?) for heat and sound absorption.

 

[sandiegojack2]

Co2 boost bucket's work awesome need by secound week flower..I use all the time vege/flower..jack ac in room is awesome idea!!! and thank's about the wife no recovery just time,. the genetic's in this plant is special have grown two pheno's and both were steller! flower when 2/3 size you want to finish! Easy grow Enjoy brother! P.S. insulated ducting is the ball's but heavy!! Use if possible! jack.

the insulating ducting will help a little with sound but not much heat absorbsion. it will keep the heat inside the duct as it exits and will not be absorbed back into the room on the way out. i use insulating ducting but i already had some laying around.

where is the passive air coming from? the closet where your exhausting to?

what kind of fan? an actual inline or a booster fan?

what kind of filter? a can filter or a home made filter?

i think it should filter/light/fan/and out the tent.

4" 160 CFM inline fan
Yes, the passive intake is coming from the closet I'm exhausting into, but only when I'm on high-stealth.
And I also don't have room for the filter in my tent, if you look at my pic, you can see the whole layout.

 

[sandiegojack2]

Smoke>>>not talking booster fan's...fan's should be putting positive pressure through light so if any leak's will not send out smell..Should be FILTER-FAN-LIGHT-OUT!!wITH NO SOFT ELBO'S USE 90 HARD ELBO'S OR LOOSE 1/2 DIA AT EACH BEND! YOUR DUCTING IS THE BEST!! ALL THE FAN MFG'S TELL YOU TO PUSH WITH FAN NOT SUCK...THEY SHOULD ALLWAY'S BLOW POSITIVE PRESSURE AND NOT TRY TO MAKE NEGATIVE (OR SUCKING) FOR BEST PERFORMANCE! jack inline fan's are booster fan's can fan's and squirlcage fan's over 300cfm do the job throttled down with speed controll so it doesn't sound like jet taking off!

I don't think exhaust out of the tent is much of a problem if it's just exhausting into a room that is the same temp.
