Capillary action

Thanks!

So, clearly it doesn't matter that the water hangs around longer in some pots because it only takes what it needs? The whole Mother Nature thing has elements of genius about it!! I'll stop putting sneaky glugs on the top of the soil now...

Watering from the bottom should make for good roots as they grow downwards towards the moisture.

does this just apply for when plants are potted on
or would it apply at the weeny seedling stage too?

What, watering like this or capillary action?

And just to muddy the waters a bit more here's another thing to factor into the equation....osmosis!

And Moon gardening can have an effect on water uptake and availability?

Snadger behave yourself!

Don't forget that the hyroponics guy posted on his blog about how some plants like their liquid nutrients to ebb and flow !

My understanding is that some plants like the soil to dry out almost entirely between waterings, whereas others need more moisture so need either more spongy soil or more frequent watering. Soils that are quicker draining, I usually add a little water at the top as well as the bottom, then the water and/or nutrients from below percolate in faster.

I've never been too bothered about top or bottom watering. As far as I'm aware, rain only falls.

Aye, the point about rain though is that it is a very effective means of exposing a plant to fungal diseases, and that is one reason why in Nature plant seedlings have a very low survival rate. Personally, I prefer to be really unnatural on this...

i was kind of thinking watering like this
i usually water teeny weenies just sown and seedlings from the top gently where there will be no damage, but perhaps the 'bottom' approach might be better??

yes, it would.
It will also reduce the number of fungus gnats you get, and the risk of damping off disease, and the risk of over-watering your seedlings.
