Aeroponik Dünger nachfüllen?

your nutes are 100% plant ready, so anyn water that goes into the plant also carries the nutrients. The plant never selects what goes in... it either physically fits or it does not. roots don't extract anything. They absorb water. There is a semipermeable membrane it'll have to cross to enter the plant. There is no 'active transport' like what happens in some proportions in our digestive systems, but not for plants. Diffusion... either it fits through or it does not. in the case of any competent hydro/soilless fertilizer, which you would have to use for aeroponics, all nutes are ready to be taken in by plant, immediately. Evaporation could cause a rise in nutrient concentration -- loss of water to evaporation and the minearls are in a smaller volume = higher concentration.. This shouldn't be an issue if the system is closed. Evaporation is occuring but if it is closed up just as much condensation is occurring and it isn't leaving your setup. Anywhere gas can escape, moisture can escape with it. Even so, it'll be minor. I'm in soilless, and whether i have 1 day between irrigation late in grow or 3-5 days between early on, evaporation is not an issue, and it is more exagerrated in my context than yours with open air pots... It should always have the same level of nutes in it when you top off reservoir. The whole idea is maintaining the ideal amount of nutrients at all times... fluctuating would defeat that purpose and cost some proportion of potential growth rate. Fine tune that EC... keep it consistent but you still have to observe and react to plant. tweak formula until you get consistent healthy plants regardless of several strains pulling off same reservoir.
