Serious Heat Issues

[bubblegumkings]

Im currently running 2 400 watters with a carbon scrubber n 4 in vortex fan for exhaust. also a 6 in vortex running from the outside of the room through a hepa filter then through the lights to cool them. Also runnin a 4 inch intake vent through the floor into in air conditioned room which is usually at 68 degrees all the time. 1 circular fan and 1 box fan. its summer and the temps are in the high 80's everyday and at 70 at night. i have lights on in the day and off at night. problem is I cant get the temps down at all. the room is at top level of the house and I cant fig out what to do. We cannot install an air conditioner in the room due to stealth. any suggestions? we first had the intake going from right outside the room but currently switched through the floor to suck up the cold air from the air conditioned room. It seems it only helped about 2 degrees. I also flowered out for about 7 weeks and my strains should be finishing up but they look like they just started to flower. im assuming this is due to the deadly heat issues and the barely if any drop in degrees in the dark period. i would like to have my crop saved but not even sure if they will keep growing or if it is alright to keep flowering them out for longer if the growth got stunted if i can get the enviroment corrceted? or should i just pull everything and make hash and try again?
Please help. Im losing big time here!!!!

Sounds to me like your fan is underpowered and your intakes insufficient. Ventilation for dummies says, 3 equal sized holes per fan. I'd get a six inch hole saw, enlarge the two ports you have and add a third at the bottom. Switch the fans so the 6 inch goes to the scrubber and the 4 inch to the lamp.

i dont understand what u mean by 3 holes for 1 fan? I should cut out 3 4inch holes for my intake? but then 2 holes would be open and only 1 used with the vortex. or do i need 3 more fans for that?
as off right now there is a a a 4 inch hole for the carbon filter going out. a 4 inch hole for the light going out. and a 4 inch hole for the intake. and 1 more 4 inch for the intake on the lights? i am confused. i had this setup exactly in a basement and no problems at all. please explain.
also i wouldnt be able to cut out the intake and exhaust ports bigger to 6 inch unless i was going to use a 6 inch fan or should i put a reducer on the end of the fan going into the 6 inch hole in the wall.

You can't suck out more than you suck in. One 4" intake simply can't feed a 4" fan. Because you've choked off the air supply, your cab has turned into an Easy Bake oven. If you want exact numbers, go here Ventilation 101 If you want the easy fix, Ventilation for Dummies requires intake area to be twice the size of exhaust or, 3 equal sized holes per fan. Two passive intakes at the bottom, one for exhaust fan at the top.

Cooling 800 watts takes 300-400 cfm. I don't know that your 6" will do that but, I'm pretty sure the 4" wont. Put the bigger fan on the problem which is heat inside the cab. Enlarge the exhaust and intake ports to 6" and add a third 6" hole so you have 3 holes per fan. Two intakes one exhaust.

While you've got double lamps the illo covers the theory. Green is cab ventilation (3 equal sized holes per fan), red is lamp ventilation. Note fans are not drawn to scale. You want the big fan on the cab.

Hey, bgk what up bro?
Freezerboy is right sounds like your ventilation is not helping you, is not just about lots of air blowing but FRESH air coming in and bad used air OUT.
Living near the Equator,gives me lots of unnecesary heat,so i started working nights, for ones power is cheaper at night so i save a bunch with my A/C unit is not blasting all day only if thermostat says so and that way i have more control so my girls can get what they want when they want it.
Another option is to get a larger A/C unit might as well.remenber that the h2O from these is destilled so is great for growing.neutral ph and 0 ppm. Easy to manipulate.

i live in the mohave desert my flower erea runs 6pm-6am 365 days a yr i run duel 400w lights.
400w mh in air cooled hood
400w hps in cooltube
i have a modified stanely blower fan pulls air through 4inch carbon scrubber into ducting to Y adaptor then off to hood and cooltube back to Y adaptor upto the stanely and exhausted into attick. my temps run low 70's lights off what my house is lights on max 85 degres
both lights side by side


colors in 85 degree temps
read the link FB gave ya on ventilation 101
sometimes i find that just by moving a fan just a tad 1 way or another can drop temps 2-3 degrees

hopefully you havent scrapped it yet

as i read this from you it sounds like your pushing and pulling air through your carbon scrubber and lights to cool them ???. i have this carbon scrubber the 4in unit http://www.nationalgardenwholesale.com/ngw/gardening_supplies.aspx?request=ECO_PLUS_CARBONAIRE_FILTERS&title=Air%20Purification&type=product attached to 4inch ducting i should use 6inch. the ducting is attached to a 4in Y adaptor http://www.nationalgardenwholesale....G&title=Fans / Blowers / Ducting&type=product. carbon filter attached to the stright end of the Y shoots off to my cooltube and air cooled hood in the above pic.
i have this cooltube 6in model http://www.nationalgardenwholesale....HORT_LIGHT_PIPE&title=Reflectors&type=product and 400w HPS inside the MH bulb is to large.
i have this air cooled hood http://www.nationalgardenwholesale....est=SUPER-SUN-2&title=Reflectors&type=product and 400w MH inside then again 4in ducting going to another Y adaptor upto a modded stanely blower fan which is rated at approx 250cfm http://www.icmag.com/ic/showthread.php?t=29341 and exhausted into my attick

i'll add 6inch ducting and adaptors would have been a much wiser choice but 4inch is what i bought at 1st just havent changed upto 6inch. my temps inside flower both lights on max at 85 degrees this still grows some dank dense ass nugs for me. my outdoor temps can be 115 during july and aug but in flower is max 85 during lights on. i run my flower chamber 6pm-6am year round i flower in a corner of my master bedroom closet just large enough to house both lights lol. both ballasts are on top shelf of closet my veg erea is in closet also it runs 6am-12am midnight. i have 1 4inch hole for intake air to flower it has this fan forcing air into chamber http://www.nationalgardenwholesale....S&title=Fans / Blowers / Ducting&type=product yes passive fresh air intake is better but again when a idea is throwen together on a whim lol ya just finish project when ya get around to it. my little chamber works produces nice nugs every 50 days so why fix what isnt broken just improve it when funds allow lol. a few members here at icmag have seen it and can vouch an say yes it operates very effectively

my master bedroom closet is 5ft deep 7ft wide 8ft tall 15 sqft floor space

i boxed in a corner with 2x4's and black n white poly white facen in outside dems are 30in deep 52in wide 73in tall.

in the desert its best to run the flower department at night when its cooler i've found 6pm-6am very effective. espically in july-aug when it can and dose get above 110 degrees every day.

if your growen in the garage move into the house in the garage in summer in desert = hot temps even with a/c unit for the grow.

if your in the house and venting your lights into the room which serves as fresh air intake exhaust lights heat into attick

if i can do it so can you

don't give up.. It's never to late, plants are great at making comebacks

good luck and my the force be with you

So let me get this right (yes i am a dumy) one fan from out to out just for the lamp and one fun on top for an exaust right???
Can u tell me what kind of fans would you use for a 400 watt hps and what kind of fan for an exaust?
i have simmilar problems

 

[bubblegumkings]

problem with the whole temp thing is because its all the way at the top of the garage like in an attic where it gets the most heat. n for now i shutdown the room and told my bud to deal with it and moved em all inside his house right in the fuckin living room. they are in a heaven enviroment now so they should turn out better. But they are already in the 9th week and the strains are 8 weekers. Also the buds are barely even there. Even if they get bigger wont thc degredation began after the 8 or 10 weeks or since they got stunted the whole time flowering they will pick up and still give same potency? this has been a complete nightmare. Thanks for all the help guys. very appriciated.

You don't need two fans, that was an example for someone who wanted to go that way. Here's one for an aircooled hood without it's own duct. Note it has no scrubber (bad idea but, that's what he wanted). Scrubber can go inside or outside but it MUST be at the end of the line. Either end will do but it can't go in the middle.



How much CFM for a 400? How cool you wanna run? Nothing will out pull a Vortex style centrifugal but, they're scary screaming loud. If stealth is part of your plans, check S&P and Whisperfans. Can't speak for Whisperfans but with S&P, use the chart to find your desired temp and go for the next stronger model as they don't handle back pressure as well as the Vortex but, they wont blow out your eardrums either. Every things a trade off.

Well I waited a couple weeks and still no change. I completely tore down the crop which was very depressing and hung it up to dry. Some of the bubble gum was frosty but after dryed it still smelled like shit. N this is very unusual for this strain(bubblegum) From previous runs that shit smelled dank the whole way through. Now its different and I Know it was same genetics cause i took the cut from my mommy. Otherr than that maybe ill post some pics up of the disaster and maybe I could make some bubble? Im not settin up again till summer is over cause it is just plain to hot and know way to cool without a/c. but we decided to flower out 4 huge mothers under 1 400 in the bathroom. Temps are great. 75 n humidity at 54 nite time 68 n humidity 55. ill post pics soon.
O and would anyone know if i would be able to use the whole plants for some bubble. would it be worth the time to make or would it just be crap. like i said before the nugs are frosty but just puny and weak.

Sorry for your loss..

Convection! Cool in hot out..

Hey I don't know if you know that there are AC units that are duct vented..

The answer is a better location for a room!

Jack!

 

[bubblegumkings]
