    Need help choosing an air conditioning unit

    as far as carbon your lucky to live in Australia where all the good carbon come from so I bet its pretty cheap. I would go with a thick 2.5 inch layer of the pelletized carbon, CAN filters use a carbon called ckv-4, i think its a 4mm pellet and they use a 2.56 inch layer. the pelletized carbon...

    Need help choosing an air conditioning unit

    yeah if your dehu is low on refrigerant is will freeze over the evap coil at a much higher temperature, like room temperature. theres nothing wrong with using a better filter with a window ac, I do so myself because the screen filters they come with are garbage and will allow all sorts of crap...

    Need help choosing an air conditioning unit

    like I said dehumidifiers have auto defrost so that they can still dehumidify down to roughly 40f ambient, at that temperature the evaporator temperature could be 20f and so moisture will freeze as it goes across the coil, therefore the dehumidifier has to be able to auto defrost the coil. like...

    Need help choosing an air conditioning unit

    dehumidifiers have auto defrost cycles because they are designed to be able to remove moisture down to lower temperatures near 40f ambient. air conditioners DO NOT have this feature and are not meant to freeze over. restricting the airflow out of the ac is absolutley not something you want to do...

    Need help choosing an air conditioning unit

    ABSOLUTLEY don't do this. your just going to cause the evaporator coil to freeze over and eventually burn up the compressor. it will also pull tons of amperage as the evap coil starts to freeze, at best that pops your breaker at worst it starts a fire. just put the ac in the window, set it to...

    Need help choosing an air conditioning unit

    yes running the ac in the window would be perfect, like others have mentioned there will be some difference between temps in the room vs temps in the cabinet but as long as the room is fairly cool and your moving a good bit of air through the cabinet (and it seems like you are) I think you will...

    New Beginnings: Tricking out a rough Grow-Room.

    sorry have been really busy the last couple days and havent been on the computer. as far as your conduit for the wiring from subpanel to outlets, you have some options. I personally like mc, also known as flex, (the metal shielded cable) because its very easy to work with and you will not need...

    Need help choosing an air conditioning unit

    your going to have a really hard time getting an air conditioner to effectively cool a space that small. an a/c with an inverter compressor would in theory work better for sure but even then its just such a small space that I think its going to have a hard time. not to mention the ac would take...

Going to rig some up and do some par testing with the phone app tomorrow to get a feel for these bad boys. he has like 30-35 more or something too so...

    building a 750w LED fixture from high bay lights

    Oh I am incorporating those, I am going to use 4 per fixture, in the corners using the part of the heatsink that is outside of the center board to attach my aluminum angle to, and using the eye bolts on the top as the hanging points for the fixture. I am also using their drivers to power both...

    building a 750w LED fixture from high bay lights

    also as far as the flex, I am fine with them moving around a little or being flexible in general/ out of the package ect, but is there anything I should worry about like the flexing breaking connections between individual diodes or anything like that? I do have oscillating fans and all that jazz

    also what distance between supports for the strips did you use for your build? It looks like somewhere around 10"or so? (25cm)?

    building a 750w LED fixture from high bay lights

    I was thinking I was going to go with 80cri just because the data sheets always seem to show 80 cri putting out more lumens, but I have noticed a lot of people going with 90cri on their builds, what is the advantage that 90 cri gives? I get the better color rendering for the human eye but...

    building a 750w LED fixture from high bay lights

    yeah the slim seems like the way to go for trying to fit several next to each other on my frame, and like you said. the diodes are the same. Will see how flexible/ sturdy the slims are and then I can decide if I want to go with those or the regulars for going across the middle. I have done a bit...

    building a 750w LED fixture from high bay lights

    sounds like ill want to buy some solid core wire then, because I dont think I have any that small, I have 1000ft spools of normal house size wiring like 12-2 14-2 etc but nothing that small. I think the local hardware store has some though, I have seen they have spools of a bunch of different...
