I always let my pots sit in run off to allow them to wick up the runnoff. People above are confusing the advice that is don't leave them sitting in it for longer then 15 minutes and don't do it just before lights out on a cold day.
Since i give the plants a wet/dry cycle i want to be sure that i am soaking them when they are watered and since just top watering in pots with dryish soil allows the water to run directly through and out the bottom unless you are doing it painstakingly slow. Now thats with regular square pots, with airpots i found it a must as the holes in the side allow water to run out, i got individual trays that were a couple of inches deep, top watered a little and bottom watered, let sit for a bit then went back and done the same until pot was heavy enough. Gave up on the airpots as they are too much hassle to water.
I only use organics and short flowering strains, i wouldn't worry about salt build up unless i had 12 week strains or longer.
The bottom of the pot sits about 1cm off the bottom of your tray, the runoff has to be more than 1cm deep to touch the bottom of the soil of the airpot.

Hello, I was wondering if anyone is having problems with your airpot taking up the feed/water runoff? I have a standard plastic runoff tray that has small ridges (X) in the tray, and it isnt looking like it is taking up the runoff!! Any thoughts ???
