This is my goto techno writeup for clone theory.

In a nutshell, high humidity air prevents moisture from being sucked out of the plant.
Snippet…

What the logic behind this step? Is it a sanitation thing?

Yes. I admit…its me assuming the chlorine in my tap water can be of some disinfectant help.
Also found that misting fresh tap on dry plastic dome leaves a nice fine even mist. Vs drippy unwiped.
Air exchange once or twice a day can’t hurt.

That was a very informative write up.
What you say about humidity and absorption makes sense to me.
Just out of curiosity, what lighting do you guys run over your clones?

I use a couple of these for rooting small groups…

, thanks for sharing anyway … 
Sweet this is pretty much what I am running them under just a little different aesthetically.
I had some in the garage that were above a former workbench that I repurposed.
They seem to be doing well under it.

That’s weird, It worked for me and I’m in Canada…
Somebody just being a ‘dick’ and arbitrarily restricting access.

What’s weirder is that now the Chinese are the only defensors of the worldwide free markets and commerce against American protectionism! 
OP: sorry for the offtopic

I guess if you’re on the market for a high quality product like mars hydro 
totally agree about the second part Uncle Sam sure does like to export “freedom” I think maybe they believe it should come with the Walmart/McDonald’s third world starter set
@Zenki I use a t5 with only two bulbs in it for a 120 site cloner so it doesn’t take much light at all I really wish I would’ve seen something like what @GramTorino suggested it looks perfect for cloning
