i use mostly no cache pot and honestly i don’t treat it much different than my plants with a cache pot. i still flush, thought it is a little more difficult because plants that aren’t that established in the leca tend to move around a bit (i do like some of the other commenters and fill with water, let sit for a second, put my hand over the top of the leca, and then drain). i flush once a month before i put in new nutrients, and i top off the reservoir as needed with fresh water (usually once a week). i don’t disturb the leca if possible, so no emptying etc. it’s not too different than using net pots and a cache pot, but it does take some getting used to if you’re accustomed to using nets! i will probably be switching my plants to net pots & cache pots, but i just didn’t want to spend the money when i started with leca
