i water every day for the most part yes i do skip a day every few days, but heres the thing about coco it physically holds more air and water than any other medium that i know of,by watering everyday im putting MORE DISOLVED OXYGEN in the medium than watering less often, see the plants use the o2 pretty quickly,then theres less o2, by adding water its pulling more o2 down into the coco, i also keep a couple buckets bubbleing 24/7 , one is usually nutes&mykos, the other anything from plain water to humate tea, i rarely put plain h2o in my plants, if im using reg salt ferts i always ph everything to 5.8, so contrary to the "soil mindset" watering daily in coco keeps MORE o2 in the rootzone, it is more or less impossible to overwater using coco as long as the container is well drained, i have actually tried to drown a plant by overwatering, the result was that plant grew faster than all the others!!! (enough proof for me)
i read extensively on this and im not the first to discover this charateristic of coco.
and the other reason for this practise is when coco dries out the suspended nutrients in the water dry out and begin to crystalize this can cause the ph to rise or fall sharply, this can be very bad obviously, and with organic nutrients it can cause massive microbe die off locking nutes out completely untill the microherd is re-established, because coco "looks" so similar to soil we are easily fooled into treating it like soil, i assure you its behavior and subsequent treatment are very different, its hydro for all intensive purposes, so just like its a bad idea to let your res get to low and nute levels rise to the point the ph goes wonky and plants get nute burn, the coco is the res and the medium at the same time, , in any form of hydro the more disolved o2 in the solution the better the same concept directly applies to coco, well guys i hope that clears it up as to why i water most everyday,
bear in mind when i grow in soil i dont apply this technique, i let them dry out real good, several times during the cycles,kinda like they talk about in the green house seed co vids.
