    Looks great Kg.... and somehow familiar

    With the constant fresh air input condensation isn't really an issue. When running, my setup never fully reaches saturation. The mist is dissipated a foot or so past the outlet.
    If it does then things are out of balance somehow. Tweak your airflow/moisture output, condensation is a waste product in this case. However, I do have pans at the bottom to catch the run off from watering. In addition, make sure the humidifier outlet tube maintains a degree of slope so any condensation inside the tube is allowed to run back into the humidifier and then be recycled.

    Your performance numbers look good.... and be sure to install that second fan and power supply. It's tempting to do but don't slack on that issue.... it can come back to hurt ya real bad.

    You might end up moving the humidifier output closer to the fan.... depends if the negative pressure differential developed by the inlet air velocity is sufficient enough to induce proper blending of the two from that distance

    In other words.... make sure the fan sucks the mist into the airflow

    Its a little counterintuitive but with this type of system, you don't want to see the mist sinking or collecting somewhere. We want it fully blended to get the maximum temperature drop (latent heat of vaporization)


    just for fun, a little about Bernoulli from the master


    and an old school vid on refrigeration

    thanks av. i really appreciate the help.

    The mist is instantly sucked right to the fan and then exchanged from that distance, so i am happy with that. I am still tweaking with the humidifier to avoid having it run on full power. i am also really happy with the temps. My night time temp got to right around 60 degrees, so i have a decent drop.

    I have moved many of my plants and i have the helis on the left side with the fan and such. i hope they like it =)

    that humidifier pumps out a nice mist, but it just sucks up water. ive had to fill it twice already today so i went ahead and bought a Vicks Ultrasonic Humidifier - V-5100-N. this one has a 1.7 gallon tank. it shouldnt be here for a week though.
