All good advise, especially the room temp water that Gazoo pointed out.
I have found it beneficial, to hang light hangers over my dunk buckets, and set it to a good height, dunk and top pour water, or drench, wait till the percolating bubbles stop, (about 1 min) and then pull the plant out of the dunk water/drench and hang on the hook to drain the perched water. Then I move on to other garden duties, and come back in 5 mins to the next plant to be dunked. Obviously this really helps if you have a bunch of plants to dunk, and most of the time I have two dunk buckets going. I find plants I do this too get the most from this wet/dry cycle and just as important, a fresh air exchange in the soil. I observe the best results when the dunk bucket is full so the drench comes up to almost the top of the pot I’m dunking, really forcing out all the air from the soil. Then conversely, when the pot is pulled from the drench, the rush of draining drench water sucks fresh air in from the top. Hanging drains most of the excess, and the plants seem to love this.
However, for those who need to conserve products, this tech does have some leftover. I just feed my compost pile the leftovers , and the garden has never been so good.

) is that some pots have their drainage holes in the sides of the containers, or in an "indent" in the bottom that places them above the very bottom of the container which is why it's important to tilt & drain. Depending on the container, just letting them sit may not drain all the water from the bottom.
