Hey thanks peat. That is helpful
I just put some clones from rapid rooters into dixie cups with botanicare coco and using this formula, the cups dont seem to dry out after a day or two should I be watering them anyway? they seem pretty weighted still
If your cup has drain holes, then the coco will not hold enough water to keep the roots saturated.thats interesting you say that h3ad. even with an underdeveloped root system? seems when ive tried repeated waterings,--say when the beer cups are still nice and heavy--plants always seemed water logged, slow growth follows.
can you help me to understand how a plant, whose roots are submerged in water, can breathe? i know in a solo cup, an underdeveloped cutting isnt submerged in water, but its roots are completely saturated.
The additional waterings are the air supply. As the new water drains through, it forces existing air out of the root zone and pulls new air into the root zone. It is this exchange of air which allows for enough oxygenation, in addition to the fact that the new nutrient that you water with should have a higher dissolved oxygen content than the stagnant solution suspended in the coco.if that saturation, still exists, for whatever reason, why would you push more water? dont we need some sort avenue for the supply of oxygen? (i wanted to write air supply)
I mentioned always having runoff, that necessitates holes in the cups. You are not so much "adding" water as you are "exchanging" water.lets use your dwc example as an example. how would a plant continue to carry out all of its functions in a dwc setting if we removed the oxygen supply? it seems thats what were doing by adding more water on top of an already full cup.
again, im not talking about a plant in a big pot with a developed root system, were talking new cuttings. thanks for the help, h3ad.

i follow you exactly, and i have a pretty firm grasp of the mechanics of coco, but i guess what im suggesting is this:
say you have a cutting in a solo cup (with holes ) that for whatever reason (conditional factors, plants not taking up a lot of water, etc) the cup is still saturated. at this point, no air has been able to rush into those spaces left by evaporating liquid. basically soggy coco.
what were presupposing is that the coco, and this is crucial to what im saying, has had an opportunity to dry (even a little). in your scenario, when you water multiple times a day in a solo, with, im assuming a underdeveloped root system, that the time between irrigations affords the coco an opportunity to dry (ever so slightly), and allow for air to come rushing into those spaces.
i can just see a kid growing with cfls (or floros) in his closet,-- temps at 64* rh 60, and no ventilation,-- is gonna have some serious issues if he keeps dumping water on underdeveloped roots in solos.
everything you say (and have said) makes perfect sense to me, h3ad, i guess what im positing is more contextual. or, a better way to say that is conditional. not trying to debate a gray area with you, just hoping to gain a little insight into becoming a better gardener. again, thanks for the feedback.
