Definitely not a great idea to do. You will run into salt buildup no doubt. You can however use some run off water to water any other house plants you may have but I would only do that like once a month depending on the plants. I just pump it right into the drain.Hello growers !
are you throwing away the run off water from your pots or you feed it back to the plants ?
I have been sucking it up ( not by mouth) and pouring it back into the plant, until recently when I realized the big difference in EC/PPM of this water that passed through the soil vs the same water before watering the plants.
I recently purchased a pH and EC pen and was surprised by some of the measurements that came out....
I filter my tap water before drinking and for the plants too with a Berkey carbon filter system and the pH ranges from 7.1 to 7.6, ppm500 readings are very low with a value of 10 and the corresponding EC value on the pen shows 0 ( both bluelab pens ).
I was surprised by the EC/ppm level being so low so that I thought the pen was out of calibration, so I did calibrated it just to make sure and the reading came out as wrote above.
I did some other test with water that has some dissolved salts in it and the ppm/EC measurement was way higher....so it seems like the pen is telling the truth.
I thought the low ppm value came from the effect of the carbon filters but after doing a cross check with unfiltered water the results are pretty much the same.
So it seems like water here is very "soft", in fact all my appliances that use water ( kettle, dishwasher etc ) has no traces of salt build up.
Now back to the run off question...I did another pH and EC test on the run off water and realized that the ppm/EC values are waaaay higher. Of course water dissolve minerals as it passes through the soil but I was surprised to see that the EC value went up to 4.6 and ppm500 around 2300.
pH stayed fairly stable to what I feed with ( I lower the pH before watering using earth juice pH down to a 6.7/6.8 value ).
I'm trying to grow organic and it seems like the pH is not so crucial as in other grow styles but I still try to feed with a more correct pH as 7.5 ( as average for my tap water ) is a bit on the alkaline side for what ganja needs.
So after all these discoveries I then thought that pouring the run off water back into the pot is maybe not a good idea considering the amount of salts dissolved in it.....
I'm going to do a slurry test soon just to see where I'm at with the soil itself.
thanks for confirming this..I'm not sure if I rememebr correctly but in the book True Living Organics by The Rev I thought I read something about pouring that water back into the pot. I may have mixed up my memories of that. In fact using the pH and EC pen really helped to get a better idea of the whole system I'm dealing withDefinitely not a great idea to do.

yes you right, it just happens that I always pour a little bit to much...I should just learn to be more patient and add little by little. I water concentrically from the stem outward, the water that hit the internal pot's wall runs down faster along the wall. With fabric pots this happen less, which is why I may switch to those on the next indoor runIf you’re growing organic, you shouldn’t want water runoff.
How big are the pots?yes you right, it just happens that I always pour a little bit to much...I should just learn to be more patient and add little by little.

5 gallons , plasticHow big are the pots?
I reuse it for next wateringHello growers !
