first off, i hope i am posting this in the right spot. i am planning on installing a passive intake vent in the floor of my mobile home to the underside where all the shady cool air circulates. has any one done this before or know anything about it? i am thinking of welding two floor vent collars together face to face, buying the vent registers and screwing steel screen to the top of each register. then cut a hole in the floor through the insulation to the underside and then drop it in and before i screw the top vent register to the floor, stretch pantyhose over the hole and then screw the register down. this way i can change the panyhose easily if need be and i can make sure no pests get into my grow room. any thoughts? i'd love any information anyone has to offer silent spectator
That sounds interesting however how much insulation will you have to get through? I thought mobiles have a airspace?
not really much inulation. a few inches and then open air space underneath the trailer. we were just under there today running wires for a new breaker and installing outlets.
It's not a bad idea that you are describing. The pantyhose is a good idea so that small bugs don't get drawn into the intake, and you should have a nice supply of fresh air coming in. The only problem I see is if you plan on growing in the winter you will have a problem warming the air for the plants....otherwise than that it sounds good!!..
not sure about how to heat the air i have everything figured out except for heating the air? any thoughts,
Another thing i would suggest to keep the war against pest won, jimmythelizard pointed me in the direction of some stuff called diatomecious earth, you can get it at a nursery and it kills all types of insects and pest. I had a thrip and symphilids problem the begining of the week used this stuff and bam everthing is undercontrol. I would suggest getting some of this and sprinkling it around the floor of the grow space and also in the top of each pot every cycle. The stuff is safe for humans and animals just not insects it damages the exoskeleton and cause them to dehydrate. the food grade is what you want and is a fine powder heck you can even dust your cats and dogs with it for fleas, or feed them small amounts to fight against parasites.
hmmm sounds like a good plan on paper... my q to you would be this.. : id assume your in a park, including neighbors (living close to your site), if your cirrculating air underneath or moving it above (your trailor) the smell can become a huge security issue... this might be a good time to get a scrubber in tandum w/ your new project idea... safety 1st, sticky buds 2nd! peace ss ~Wizzle
Yeah might just live out in a rural area i grew up in a double-wide way out in the country. Wish i still had no neighbors.
the scrubber would be needed but the other advice i would give you would be watch how much electricity your using, if a trailer is drawing a shit ton of power to it then someone might look you over. but thats just a thought, im not sure how often power companies actually wonder about that stuff. sounds like a good set up though.
we are on 14 acres in the country so i am not worried about my neighbors as much as i would be in a park. we already draw a ton of electricity because we are all electric and i have a ton of large appliances. i have a 400 watt hps that i am going to use (brand new, still in the box) i am buying an 8" fan and corresponding scrubber along with an oscilating fan for circulation. i am unplugging one of my deep freezers that i am not using anymore to compensate for the electricity i will be using, i have even been still running this freezer at half full even though it costs more that way because it works so much harder. maybe this way if the bill goes up it will only be a little. i am also going to paint my roof this spring to help keep the inside cooler and reflect the heat, so that will save me on the electric bill some too. i have done significant reading on this subject here on the site and i have several books as well. :qgaraduate: i feel very good about our plan so far but i am a little baffled about this passive intake stuff. anyone want to point me in the right direction. i want to have the option to use my room (a walk-in closet) year round if i want to.:new_smilie_colors1: thanks guys! silent spectator
I'd think you need to plan the air flow. In and out while keeping a negative pressure in the room. I'd pull over the tops of the plants to draw out. Passive is passive. Air can flow both ways through a hole in the floor. Into the house and out the house depending on air pressure in the house. I've grown with cold mountain winter inlet air. Worked fine. I'm not sure what help that post is.. but... I do work the air.
yeah, looks like all your ducks are in a row. as far as a passive intake is concerned, if you couldnt understand tech. mumbo jumbo, it means that no fan is connected to the intake pulling air in. an active intake with a passive exhaust pulls more air into the room than is pushed through the exhaust causing air that hasnt been put through a carbon filter to leak out of cracks and alert neighbors. using a carbon scrubber to filter mj smelling air requires an active exhaust, passive intake so that air is being pulled through the filter faster than it could leak out of any cracks, or whatever in the room, creating a negative airflow like randy said. this means a fan connected to the exhaust. i hope i didnt lose you there, but a negative airflow is basically for making sure smell gets filtered before leaving your room, (unless there might be another reason im forgetting about.) thanx for the props skunky! you guys teach me what you learn, and im happy to return the favor!
Heating issues!!! Yes i have one idea here my friend, Just after reading your interesting and profound way of making a vent for your MJ....sounds really good, though for your HEATING plans, i would, as simple as your puttng everything else into good use as you explain, i would(in the WINTER) use some mylar, and tape it up round the hole thats letting too much coldness get in, so its easily removed with the taping for any reason needed, and that will stop any , or too much air flow getting in, especially when it gets COLD!!! Just an idea, but it sounds logical to do so, expecially for the way your planning the rest!!! Some mylar around the hole for fresh air, or even, a low fan heater inside, in the winter would/could do the trick, and that's without having putting mylar over the air vent in the winter too, as its underside of the van, no-where else!!!(Always great to get FRESH AIR, as FRESH AIR is your friend!!!) Sounds all good to me my man, Keep growing, n keep up the good idea's to, UrBigBuddie..........:sign13: P.S, As easy and as effective as your plans for the rest will be(And that sounds a great plan for your set-up!!!)

thanks thanks for the help guys. i am going o look into a fan heater if we decide that we are going to need it. right now we are going to just grow in the spring and the fall. i think where we are that will be plenty for me and be possible for our temps. silent spectator
Just how cold does it get? I grew in an outdoor shed last winter here where it got into the 40s or a little below. It's definately not freezing but it wasn't warm either. I just used the lights (roughly 700 watts including a 400hps) at night and off during the day so the temps stayed a little mored stable. If it's crazy cold then you will need a heater like ur planning.....but if not then you can just do what I did. My plant (i focused on one and she was huge) gave me a ton of good bud with no ill effects from the cold.
