If your growing in organic soil you don't want any runoff, a couple drops if anything. If your using living soil the run off is taking some of the food away from your soil.I’ve been letting them sit and reabsorb the runoff but I read this morning that that’s bad for bottled nutes. Is it bad when you’re growing 100% organic?
Or use the SIP method.You also might want to consider bottom-watering, like putting the water in the tray first and letting the plants suck up what they need. Then remove excess water after 10-15 mins
By runoff I am assuming you mean water that has drained out of pots into a suspended tray.. If the plant is sitting IN the runoff as long as its not flooded out you can let the plant drink it back up no problem in Soil.You always want to get rid of runoff unless you're growing hydroponically. It can attract and breed bugs, disease etc..

I’m in three gallon pots and when watering with 8 to 10 cups of water there is about a half inch to an inch of water which reabsorbs within 30 to 90 minutes.How long does it take to suck up the runoff? I usually give like 10-15 minutes and anything still left in the tray after that I get rid of, or use to water a houseplant...
Exactly. If you don't plan to add food to the plants later you do not want the nutrients leaching out of the pot through irrigation. If you planned to fertilize it later or add more nutrition then this is less of a concern. There are many variables.So what I understand is if you’re growing organic you just want to water and feed without much runoff but if there is a lot of runoff it’s ok to let it reabsorb into the plant.
Thanks to all who responded.
Yeah. If I use 8 cups it reabsorbs within 30 minutes but if I go with 10 cups it takes much longer. Thank you, but why would it make a difference.90 minutes is a bit too long imo. 15-20 min tops
Technically, you could manage to find the perfect balance where your essentially using your media as a rez. But this would be very difficult and would likely result in failure.If you feed once a week with organic nutes at 1100 ppm with no runoff or very little runoff, watering with plain water once in between feedings, also with no runoff, will the nutes build up in the soil and cause a toxic environment?
