King these are in 5 gallon bags that have about 4 gal of dirt.  The roots have grown through the bags on bottom and sides ( not sure if that's a good thing), feels like the whole dirt ball has roots.  I poured the flush water fairly slow.  Would get a small puddle and let it soak in, then repeat.  Once i had a good amount in each pan I stopped pouring, and very well could have had some water run down the side of the bag.  I'm interested to see what the root ball looks like after harvest
