The only place I can find good, stack-able 66qt clear tubs is Big Lots. I don't know if you have one of those around you, but there selection of storage tubs is awesome. Target has them too, but there aren't any of those around here. Here's the tote.

I feel dumb that I didn't know that humid air is less dense than dry air.

Thanks for the replies. A pattern you may notice in my teks is that they are as simple as I can make them. I try to stay focused on one particular area so the noob doesn't get overwhelmed with info and get lost. This one is just about how the tub works, the thought and principles behind it.

In my humble opinion, talking about too many aspects of growing on one thread makes for a long and confusing thread and many noobs will just not read it and miss out on good info.

I prefer to make multiple short teks so you can key in on the main points they are missing.

Abshroom, as far as your situation goes, I don't know what else to tell you, sorry. I just don't know the best way to do things differently than the way I do them. That's why I do what I do. If that makes any sense. This thread is about set and forget monotubs.

All I can really tell you is to fan it out, keep an eye on that potential contam, see what happens. You may be wise to make a post asking your question in the main forum. Good luck to you




Thanks, that's what I love about your teks. Not only are they very clear and get straight to the point, but also explain concisely why you're doing what you're doing.

Just out of curiousity, anyone here who has made a Monotub before - have you soaked the grains, a'la Franks Tek?
Thanks

Yeah i have. I get good results but I usually get pretty good results anyway. I use MS most the time..

It can only benefit you so you may as well make a habit out of soaking your grains before spawning. I do occasionally forget :rolleyes:

@Dos Ounce
Thank you for your response! I just shook my grains so I got a wait a few more days I think, before I spawn - good to know :smile:

With regard to the humid air being lighter, I didn't realize this either. It's somewhat non-intuitive...

H20 has a molecular weight of only 18, while diatomic oxygen, O2, has a molecular weight of 32, and N2 has a molecular weight of 28. So nitrogen and oxygen, the main components of air, are much, much heavier than water.

When air gets humid, the water molecules actually displace the oxygen and nitrogen, so the average density of the air goes down.

I was originally thinking of the water molecules as joining the party and making the whole thing heavier, but they actually push oxygen and nitrogen out of the way, generating buoyancy in the process.

CO2 is also at play here, and it's heavier than all of the aforementioned molecules, with a weight of 44.

http://en.wikipedia.org/wiki/Humidity#Air_density_and_volume

Humid air is less dense than dry air because a molecule of water (M ≈ 18 u ) is less massive than either a molecule of nitrogen (M ≈ 28) or a molecule of oxygen (M ≈ 32). About 78% of the molecules in dry air are nitrogen (N2). Another 21% of the molecules in dry air are oxygen (O2). The final 1% of dry air is a mixture of other gases.

dude molecular weights don't make a difference if you have decent FAE, it will all be mixed up evenly.

It depends on the concentration. CO2 is only present in very small concentrations so it diffuses quickly and has little effect on air currents. Water vapor can play a dominant role in the way air currents move especially since it's evaporating so it creates temperature differences as well as differences in density.

:whathesaid:

I think tiltajoel  was just pointing out that humid air rising is counter intuitive (and commonly so because, in part, we mistakenly associate condensed water like fog and dew with water vapor).

Then, he is pointing out the science that shows why he was mistaken and his new understanding.

But, you are correct, Dos. The molecular weights are not important, unless you want to understand the fluid dynamics.

Without realizing humid air rises, someone may not see the need for a fan in the room and then may need to set up their monotub differently.

I learned a lot from them. This is how I do pretty much all my prep (except I follow PastyWhyte's mini mono tek).
