If you're a baller-on-a-budget like myself, then you know what it's like scavenging your area for anything that can be put to use for your grow room. Cooling your room to lower temps also gets the purple to be more vibrant during the flower cycle 'nuff bullshitin, lets get this party started Supplies: -$4 styrofoam cooler (mine was $7 because i chose the big box, cuz you know, im a tough guy, toughin around toughtown with my big ass dick) -$4 6" fan -something to vent the outflow of air such as dryer vent or you grow room vent ducts -water bottles you can even put this cooler in series with your pre-existing inlet ducts to cool the incoming air. hot shit right? The Build: https://www.youtube.com/watch?v=FaC0dlRENk0 Step 1:We need vents for the cooler, so trace out 1 hole for inflow the same size as your fan (keeping in mind that you should cut a little bit on the inside so fan can rest on top of the hole). As for the outflow, you want it to be a snug fit, for ultimate satisfaction. Step 2: position the fan (or vent line) on top of the air inlet, and the insert your outflow positioning device a.k.a. dryer vent/ air duct (I was about to use a paper towel because obamacare) WARNING: CLEAN OUT STYROFOAM THOROUGHLY BEFORE INSTALLING IN YOUR GROW ROOM. Step 3: Ice to meet you Freeze some aqua bottles or gallon jugs (water bottles work colder but don't last as long) Step 4: ??? Step 5: profit Some notes before get started: -I use 3 jugs of water that lasts the whole day, using water bottles might need to be switched out -make sure you remove as much as the styrofoam as you can before running it, Then run it in a kithen or sweepabale area to blow away the last bits and pieces. THEN you can move it to your grow room.
Nice job I saw these being built out of those 5 gallon coolers as well. The big ones that u get at home depot. The styrofoam coolers are much cheaper though.
might give this a shot might need the added cool air once i throw up my 600w B) got my 400w within a foot of my canopy atm at 75F, gonna try to get the 600w just as close
Dry ice produces a shit ton of C02 unless im mistaken... could be extremely useful to us man! I would love to see someone experiment with this! About the OP: maybe we could use like one of those slim gatorade coolers like you see at football games with blue-ice packs to save space buds, bitches and bandos
not if you close the bottles up. As for the dry ice, i've been looking around for some cheap dry ice but i can't find any. I've wanted to try it for quite some time. And yes, it will produce a lot of CO2 because thats exactly what it is: frozen CO2
Dry ice would melt way too fast and is expensive as can be... but a good thought and yes it would inject a lot of CO2 but at a rate much higher than 2000 PPM Nice design, good bang for your buck no doubt!
Just a heads up, if you put Salt in the bottles before you freeze them, the Ice will be colder and take longer to melt. I use a variation of this, but I put water in the cooler along with the bottles of water. I also salt the water in the base of the cooler. This serves the purpose of lowering the freezing point of water so the water in the basin can get much cooler without freezing and give a much larger surface area than just the ice jugs alone. I put a couple 1 gallon ice jugs in mine and it lasts about a day and a half, and is super cold. As for adding humidity to the room, when you have water in the basin like I do yes it adds humidity to the room. However if you are properly venting the grow area it doesn't become an issue. (I operate hydro system anyways.) Dry ice is not a very cost effective way to cool a room, however it would produce a lot of CO2, I have seen people use it in CO2 generators.
i figured the condensation from the bottles unfreezing might be something to worry about, especially when your fighting already high humidity as i am.
on a side note, my humidity raises with temps throughout the 18 hours on usually 86 degrees and 80 percent humidity.. but when my lights switch off around 1am, my temps will get down to about 72 and my humidity is almost always 50 even. i figured keeping the room in the 70s will help me control humidity. my idea was to adopt this diy and instead use the negative pressure to draw the air though the cooler instead of a fan. cut and put a floor or door vent on the top and cut a hole in the bottom to sit over my intake. use a piece of wire screen in between the intake hole and bottom cooler hole so the bottles dont fall down the intake run.
i'm not tracking and humidity changes myself. theoretically the condensation is from the air inside the room, not the from in the bottle. my guess is that if your inflow air is getting cooled by the poormans AC, the humidity might linger a little bit because of the denser air.
You put the > sign the wrong way. It should say <8$ implying that the quantity you pay will be less than the 8$.
I was thinking about using this outside of my grow tent and having a duct leading into my tent, that way I dont waste any grow space. Also, with regards to the dry ice thing: since it produces a lot of CO2, would it be a good idea (and cost effective) to put a little bit of dry ice in with all of the water bottles/jugs to get some CO2 but not a ton
