New Grower Bad air circulation in small tent, Help needed

[Budson420]

Hey matey, i recently had high temp problems to mid 30's was painful to watch the little girl struggle in there, i froze bottles of water usually around 4 bottles at a time, you could place those in your tent so the fan blows cool air off them, i had an intake duct running out of my cap into a 24lt plastic tub i filled with water, had the ducting running under water and filled it up with the bottles, it helped a little but i use CFls you have HPS so i dunno how that would work for you its only a short term kinda thing, adding some C02 helps the plant in high heat.. just an idea, but a cool tube for your light would be the best option, low budget and heat problems really suck its kinda the biggest pain, any other issue is usually cheap n easy fix besides heat, regaurdless in what you do best of luck keeping them temps down bro!
peace!

Cheers budson,

Growing organically and tried to get this setup nice to produce some clean tasty buds but just all useless to a degree if cant sort this lol. Yea heard to fill a bucket with ice cold water and place under a fan but does this affect humidity, plus is only a short term solution. Even have hot water bottles in there during lights off to bring temps up by a few degrees to try minimize the temp differences. Does a cool tube link up to a seperate filter or simply cool the hps and the other carbon filter draws that out? Sorry for all the Questions but I can only afford make 1 purchase,

All the best,

I think i see your extraction fan at the back to the right of your carbon filter. It looks pretty hefty.

Presuming it is pretty hefty.

I would buy a cool tube and some ducting. move the carbon filter to this side of the picture closest to our viewpoint. Attach the filter (with some ducting) to the light cool tube on this side.
on the other side attach some ducting to the out take fan which has ducting heading out of your tent to the bathroom fan.

Try and use the smallest amount of ducting you need with as few bends as possible.

Presuming the out take fan is up to the job, that should fix the problem.

Aa right so get a cool tube inbetween filter and extractor? Are cool tubes sealed off so the filtered air eventually leaving the tent is still odourless seeing as it has to pass through the light after the filter?

just replace the hps hood with a cooltube!!

or an air cooled hood

Yeah i think we're all on the same page hehe, the fan on the other side, sucks the air through this path:

Smelly air -->filter ---> thorugh cooltube/hood ----> ducting ---->fan------> out towards bathroom extraction

What's the CFM or m3/h rating of your bathroom extractor fan? And what is the CFM or m3/h rating of your scrubber?

Do you have any more ports in the tent to run duct in/out of? And how many? And what size (like 4 inch? 6 inch?)

I think you're going to want to beef up your intake and exhaust system. An actual inline fan would draw in much more air (and potentially fresher and/or cool air since now you can run it with a duct versus the clip fan.) I would say it sounds like a majority of your heat is coming from that open air HPS reflector. If you got a cool tube, you could run duct on both sides and just pipe the heat right out of the tent. You'd still need an extraction fan for this though (inline can fans work just fine for this if you're on a budget.) Ultimately, you want to be exhausting more air than you are taking in. So your exhaust should have a higher CFM or m3/h rating than your intake. This causes negative air pressure to build in your tent; which causes air (and odor causing molecules) to gravitate towards the point of exhaust, instead of trying to find other ways to escape (like through zippers, passive intakes, etc.) If you CAN, and in my opinion, I would beef up my exhaust fan on the scrubber and have that be your primary exhaust for the tent. If you got a cool tube, you could even add that in the series of duct and kill two birds with one stone (I exhaust my scrubbers through my HPS; it works just fine.)

I also agree with komach; if you're going to have the fans directly on the plants; it should be at a lower speed and would be really helpful if it oscillates. Nature doesn't blow like hurricane 24/7, ya know what I mean? Hahaha! Having the plants moving slightly helps strengthen the main stalk and branches, and moving leaves are less prone to stagnant light burn or hot spots (in my experience.)

Anyways that's just my "My 2 cents" :karma Cloud:

Sweet, that's where I was getting confused... Didn't realise cool tubes contained the smell.

I appreciate the help and will hopefully get this sorted asap so these babies can grow into something beautiful.

i didnt have a problem with humidity i live in a very hot and dry area in aus at the highest humidity might get to 23% so any added wasnt a big deal for me.. though i dont even know the actual proper humidity levels your meant to have whilst growing? fill me in if you know bud, it should all conect together nicely like lego if you get the right sizes and like blue said keep the ducting little as possible and try not to make any corners, this will just make your fan work over time and wont be enough power to get all that air out :Sharing One:

scrubber is 145 min m3/h 187 max m3/h but not sure about the small fan or bathroom extractor, anyone know a general amount these run at? Also there is another 6" hole at the back of tent that isn't being used.

Humidity is staying between 45-50 & have an oscillating fan that will be put in

Cheers for the patience so the plants have a moving breeze over them
