Rain is not expected for one week and getting water to my plants will be challenging, so I was wondering how old plants have to be before they develop the ability to pull moisture from the air?
How old do plants need to be to pull moisture from the air?

Uhm.. Unless I am misunderstanding your question, they don't ... Water goes in thru the roots and out thru the leaves. High moisture in the air slows down the plants' ability to transpire (release water) but I don't know of any circumstance where the (weed) plant absorbs needed moisture strictly from the air.
All that said tho, those plants should probably be able to handle a week by now. I would start out on the slightly too much water side and you might get a few yellow leaves, but it will be longer before they become completely dry that way.

They won't develop that no matter how old they get. They do have a very minor ability to take in small amounts of water through the stomata openings, most of which are on the underside of the leaf.
In emergencies some gardeners can use foliage (foliar) feeding as a way to get nutrients or minerals to a plant when the roots are not able to absorb as much as they should. In the long run though, this is not as effective as the root system itself.
If your young plants are already in the ground then a good watering should be enough to keep the soil moist for a week and allow the plant to take up the water it needs plus continue to increase root growth.

Ah, I see.
They got a drink but some of the plants went into some pretty dry soil and they got to wait a week for rain. Hopefully they hold out till then.

In previous grows my plants went into relatively moist soil with rain only 2-3 days away, this time however most of my plants are in dry soil with rain one week away. I guess I'll get to see how tough these plants are.
Let us know and maybe a photo as long as the picture does not give away the location.
