AFTER ASKING A QUESTION A MEMBER BASICALLY TOLD ME i WAS STUPID

Yes that is exactly what I was talking about sir but if you look at the DIY venturi videos all over youtube you'll see that the intake hole you said at your shop had compressed air creates a vaccum and pulls air in automatically. The reason your shop had a compressor hooked up was probably because your shop was using that venture point to add a chemical possibly or to mix massive amounts of air with whatever you guys needed it for. So if you make a venture ( check out youtube vids ) and this top hole has a vaccum like suction, if you routed a very small air hose from inside a freezer or from outside when it's suoer cold would that vaccum created by your DIY venturi which is now sucking freezing air cool your water in your system since it would in theory be mixing freezing air with your systems water.

So now that you know exactly what simple question I was originally asking is or what I was getting at if I didn't explain it very well (my bad) this is what I was thinking in my mind.

I only have four 9 gallon modules and a 35 gallon res. In case I decided to expand in the future I bought a 1350 GPH pump. I'm going to be running a pair of 1/4" feed lines to each module. I was wondering if on one of the feed lines I was to put a venturi that's fresh air or vaccum tube / hole was sucking in ice cold air from outside (winter) or from inside a mini freezer. And I had one of these cold air venturi injectors on each of the 4 modules, do you think or does anyone know if this would cool the overall system water temperature.

Question for all: I have a couple of those 12 outlet stainless steel air manifolds. Would it be a good idea to run a fresh air hose into the root chamber since I'm going to be going out of my way to block out any light from getting to my water?? Just wondering, thanks

well i didn't think it was a stupid question.........we should form a group of troll hunters and stop this madness !!

please link me to the thread where this happened and i will kick his ass ....... Like a true gentleman;)


Ps ...... Clever idea useing the snowy wether to your advantage :) now gimmi that link !!

The answer to your question is yes. You can setup the venturi air line to suck up the cold air from an outside source and will keep your water in your reservoir cold. You can also silence the venturi line by simply getting a old vitamin container and poking a hole in the bottom and on the top and feed the main air line from the bottom to the venturi and a short air line to the top and fill the vitamin container with cotton balls, instant silencer and no more gurgling. The plus for venturi in your reservoir is you do not need any air diffusers or any air lines running to any bucket for your DWC as the venturi mixes oxygen with the water at the highest rate available and therefore no air pumps necessary.

Thank you very much. Look what the dude wrote to me when I asked the same question along with his buddy.

https://www.rollitup.org/t/asking-for-answers-to-new-grow-room-design-questions-for-rdwc.859868/page-4

Thank you so much to for that SWEET ASS method to build a silencer for the venture!! Because I'd like to report that after assembling most of my new system I did what you said to test out the idea and just like you said, I WAS GETTING MORE MICRO BUBBLES (after adjusting all the venturi's to the perfect size & perfect cut angle) THAN WHEN I HAD FOUR 4' air stones going in my reservoir!! I have two 2' air stones going in each module totaling 8 air stones altogether. The 1375 GPH Element air pump I'm running after it’s on for a few minutes its blowing warm air just like I thought it would. So before I tried the venture idea because I didn't read your response until a little while ago I did this and it worked awesome.

I repair computers, electronics for a living & have a shed full of old towers. I went through and puled 7 cup heat sinks with their fans out of them. Cleaned the heat sinks with orange peel oil, little 2000 grit sand paper & they looked new. Next cleaned out the fans with Q-tips & rubbing alcohol until looked new. Fit 4 of the CPU heat sinks to places on the air pump where they laid the flattest. Then hooked up the fans to an old power supply, kicked it on, air was coming out of the pump at 71' compared to the 85' it was before. I did the same thing with the other three heat sinks to my water pump connecting all of them to the same power supply. I used JB WELD and put 4 small dots worth on each corner of the flat side of the heat sink then multiple rubber bands to hold them flat and tight with probably 85% of the heat sink sitting flat with no jb weld in between.

After reading your response I did exactly what you said and it worked very good. Between the waterfall effect + the venture injection sucking 30"F air from outside it's def dropping the water temperature very well. After I add a few more heat sinks to my water pump getting it to almost no heat, I think with the venture cold air injection, the two misting heads creating the waterfall effect I'm pretty confident I'll be able to get rid of all the air stones. Plus since I am using such a much larger than I needed pump (1300 GPH) with only maybe 40 gallons of water tops, I'm also confident that if I put venturi air injectors on both of my 1/4" feed lines there will still be enough pressure to make the misters run at full blast still & this will also be a fresh air injection right into where my roots hang in their 7 gallon space. I've read fresh air for roots = monster healthier roots. Well I'll let you know how it goes after my clones get into the modules. Thanks again for the help everyone!!!

Oh and if anyone else is wondering, after making the silencer twisted described, the venturi was absolutely silent and you couldn't even tell it was there. If I would have known about this I could have kept my entire systems water cool without any kind of chilling and also saved power not using the air pump. Thanks again for the venturi silencer idea!

iS THIS A RETARTED QUESTION?

In a recirculating system or DWC or any system using air in hydroponics, if you were to fashion a venture valve onto your res would it cool the water at all if the venture was set up top suck the air from an ice cold place like outside in the winter or from say a freezer. Would this air injection while making bubbles cool your water? Seems like an innocent question... According to another member I need to stay on my meds...

he wasn't being too hard on you buddy, you should see some of the abuse that @mainliner receives

im glad it all worked out for you :)

next time youll know not to ask a stupid question lol

haha yup. If I would have taken the answer they gave me I would have never even tried it. I guess I forgot how some people on the internet are such know it alls and tough guys. It would be funny if dude called me stupid and then had to say it to my face before he could post it. A lot less keyboard killers online if they had to talk trash to my face. I'm 6'4 270 and never have anyone talk shit to me. It's not like I think I'm some tough guy, but it's crazy how there are so many people online, even in these forums where we are all supposed to be helping each other that are just straight up jerks.

But like dude above said, they are probably explaining their mythical grow rooms, live with their mom, and buy dime bags of dirt weed. So they get on here because their profile portrays them as someone there not. I feel sorry for them. Thanks again for everything man! When I finally get all my Mylar on the walls and ventilation ran, I'll fire up these lights and start a grow journal. Got my Heisenberg tea bubbling in the other room getting ready for beginning of next week. Just trying to figure out how I can hide these intake vents and exhaust vents on the outside walls of my place without them being noticeable.

Flir is illegal for the cops to use here in Michigan and I have killer carbon filters for smell. Just trying to think how I could disguise these fresh air vents. I have a couple bird houses attached to the house outside on the walls in a few spots to hide all 4 of my cameras. I built them with a piece of one way glassd and air tight / weather proof to make them last longer. But it would look kind of funny if I had an extra dryer vent or 4 more of these bird houses which would have to be much bigger than the ones hiding the cameras. Any ideas? lol My room is only 3 feet above the ground level outside so the air ducts will be only 10ft above the ground from outside and air moving through these vents is probably going to be noticeable unless I can disguise it. Was thinking of venting the hot / warm exhaust air from my lights under my place than running a 20 ft ;piece of PVC along my water main with holes to help keep mainline warm in the winter. Winters are cold here in Michigan.
