try putting a few drops of dawn dish soap in your water. the soap acts like a wetting agent. google it.
tried to look it up but all i found was dawn dish soap being used as pest control
what i usually do is just pour really really really slow for the first 30 seconds, let it chill for a min ya know to let it soak in, that way you can pour a little faster,but make sure you spread the water around and let it all sink it slow. be as gentle as you can to the plants, the slower you water the better. i had a couple plants where i just poured the water in real fast, you could see it pool up and sloooowly sink down, making the soil sink, increasing in rootbound problems and aeration problems.
after i water i gently but firmly place my hands on either side of the pot and squeeze together, rotating my hands around the pot. ive never heard of anyone doing this, but to me i think it helps get air to the roots, helps break up the roots a little bit for more growing room.
everything i write is my own opinion, only way to really know something is to have experience with it
