Advice needed for adding humidifier to monotub grow room (not GH)
    #21698563 - 05/19/15 02:09 PM (8 years, 8 months ago)

I'm in a very dry environment.  I think adding a humidifier to my grow room would help.  If it doesn't, I'll use it for my bedroom.  I'm running monotubs btw, not a GH.  So I don't need anything with pipes or tubes.

Any advice? I've researched it a tiny bit and there's a dozen different types... cool mist, warm mist, ultrasonic, top mist, nuclear, etc.

Anyone else have success with their monotubs after adding a humidifier to their room?

The RH outside of a monotub means nothing.....the humidity inside the tub at substrate level is all that matters...and monotubs create their own humidity.

My situation right now is that I'm getting fuzzy feet.  When I loosen the holes too much, it gets too dry.  And yea I'm in a super dry climate.

Quoted for fuckin truth. I live in a dry ass environment. Ever since I introduced casings I rarely mist if ever and can have no top holes filled. Even without casing if you can keep up misting like once a day you don't need top holes filled.

I disagree with that quote.....if we pack our top holes looser than the bottom holes, and have a fan running in the room, air is going to enter the tub thru the path of least resistance, which would be the top holes....the old stale air would then get pushed out the bottom holes.

Backwards logic.. The old stale air is more dense because of a higher CO2 concentration so it leaves naturally by gravity through the bottom holes. The pressure difference here causes fresh air to be sucked in the top.

Your logic is backwards.....the co2 mixes with the air and rises with the heat and humidity currents....

If the substrate is constantly generating heat, there is no way co2 sinks to the bottom......

Co2 has never, nor will it ever sink to the bottom of a fruiting chamber....it is not a sealed vessel.

Even in a sealed vessel it CO2 would mix and not settle to the bottom.
So what would you say the density of the air in the tub is then?

I have no idea, nor do I care honestly....(no offense).

All I know is packing the top holes lightly and the bottom holes tightly works like a charm lol.

Air will enter the tub thru the path f least resistance...the top holes......IMO the pressure difference pushes the old air out the bottom.....

So you're saying the air in the tub rises here.

and here you're saying old air goes out the bottom..

Which is what I was saying. But air coming in freely wouldn't push the air out the bottom, that makes no sense. Air going out the bottom draws air in through the top. It might in fact be less dense in the tub though even with the extra carbon dioxide in which case the air in the tub would naturally flow out the top holes and fresh air would be drawn in through the bottom.

So in a tub with enough water to have constant evaporation and high rH could have air flowing out upwards while a dry tub with low rH and high CO2 could have heavier air and the flow could go the opposite direction.

Op, I've battled with my tubs drying out as well.  I also wanted to weigh in and say that I personally have had way better results with loosely stuffing poly than franks reversed principles tub.  I was either getting not enough FAE with it or my tubs were drying out.  I know it definitely works well for lots of people, but my fuzzy feet disappeared when I started loosely stuffing all my holes.  I don't even run a fan in my grow area.  I took 13's and Citric's advice and just leave my poly loose as shit now.  I basically have it falling out.  I let a humidifier run in the room too so I don't have to mist much.  I just keep an eye on them and give them a mist if they look dry.  Once I started doing this I was able to adequately meet my cubes needs for humidity and FAE.  My yields improved. 

I'm not knocking franks tek at all.  I was just unable to make it work well enough for me to be satisfied :shrug:

I disagree with this.  Lower RH will cause tubs to dry out quicker.  Running a humidifier in my grow area (i also live in dry climate) solved that problem for me personally.  Casing also solves the problem, but I usually run my tubs in batches and don't like having to go back and do it on all of them.  Dry air is dry air.  If you are pushing dry air in, it will evaporate quicker.  Polyfil isn't perfect for holding humidity.

Thanks guys.  I'll look for a cool mist ultrasonic humidifier somewhere.  I'm sure if I spent countless hours and attempts dialing it in and misting regularly, I could probably get it to work.  But spending a little bit of money will probably make it a lot easier.  Besides, even if it doesn't work, it would still be nice to use in my bedroom.
