Why are you making such a big deal over this? I learned something, never heard of the PWT before. That's all this thread was for me, and I don't see your point? That a healthy plant will suck the water out of the pot? That is knowlegde even the most stupid knows! Of course the PWT is not a problem per se - for a healthy plant.
When I find new information related to growing I'm happy, after all 99% of the posts on forums are useless in this regard. This post was not (for me).
Just because this post was old news to you, there is no need to be a dick.
Just because your plants have no water uptake problems, you cannot assume it applies to all growers. (No, I'm not saying it's BECAUSE OF the PWT).
Just because you don't find this information useful, a lot of people might.
My point is that the PWT isn't CAUSING PROBLEMS, like Beansly seems to indicate it does. I had never heard of a PWT before this thread, so I learned something as well, but In my opinion, and it's just the opinion of a dick who apparently knows nothing at all, the PWT is beneficial to indoor container plants. Without it soil would dry out much faster--I have a Sour D plant in a 3.5 gallon pot that requires water every other day...without suspending water in the medium it would probably need water a few times a day.
Which is why I said we are really just discussing water retention and saturation, not drainage. For the vast majority of people growing in containers indoors, a wick to absorb excess water is just plain silly. Growing 101: DON'T OVERWATER--this means don't water TOO OFTEN. If you wait the appropriate time between waterings, the roots wick up all moisture...even the PWT. There is really no situation where doing anything to the PWT is necessary.
The Perched Water Table is not some mysterious layer of water that no matter what will remain in your pot, requiring additional measures to remove. A plant will use it as it does the rest of the moisture trapped within the soil matrix.
If you or anyone else is having water uptake problems, you need to re-evaluate your understanding of plant culture, because wicking off excess moisture is certainly NOT going to make the plant uptake water any faster...it will just make less water available for the uptaking.
And if your plant isn't growing right indoors it is because the controlled environment you provided for it isn't acceptable--too hot, too cold, too much water, too much/little nutrients, not enough air circulation--NOT BECAUSE OF THE FUCKING PERCHED WATER TABLE.
The reason I'm being a dick about this is because people will read this thread and say "my plant is messed up because my Perched Water Table is too big, I should use a wick" which in the end doesn't help the person overcome their problems...if anything they exacerbate them.
