Noela started grow question 4 years ago
How many times should she be watered before harvest in order to flush properly? She has been drinking about 1L every 3-5 days. She received her last dose of nutes 9/29 and soil still felt damp this morning 10/2.

Hello ! So I heard a lot of things about flushing so here are the things that are important to me : -1st°- Flush at least 7 days before harvest , the best is 10 days to 2 weeks in soil

-2nd°- To flush you need to give the plant at least twice the volume of your pot ( fully saturate your pots : for a 10L pot use 20L of water) to wash the nutrients away -3rd°- The good moment to stop is when the runoff water is clear ( at the begenning of the flush it will be brownish ) -4th°- You can flush in 2 part if you choose a long flush (2 weeks ) -5th°- After flushing try to let the medium get fully dry before harvest ( you can have a better terpene profile thanks to that ) . I hope it will help you :grin::+1:

hey noela, just water with plain water for three weeks in soil, that's the maximum flush you need in soil - keep it simple and follow the wet dry cycle of the soil. good luck crossing the finish line :rocket:

Hey Noela, so if her last dose was basically 5 days ago now you can probably plan on not too much excess nutrients in your container. My plants too have began to drink less and stay moist longer. If youre seeing the majority of the trichs being milky id say the time has come to flush, but like i mentioned if your nutrients have been low and now none you can probably get away with doing about 3 waterings where you soak the full pot and get a mostly clear runoff water. Also the yellowing leaves there mostly going to get trimmed away so dont put too much concern over them. I think over a 3-5 day period of flushing you might see your trichs turn some amber. Also if you can manage to lower your night temp by a few degrees that can help with the sparkle. Congrats on having such a great looking end product. Now on to the fun trimming. :v:

Hi @Noela! 1L is not enough, you must have a runoff in order to flush properly. You don't want to create an over-watering situation either (unless you're having a serious nutrient lockout), so use approximately ~30-35% of your container's capacity, this should give you a slight runoff and won't be wet for too long. If you do it 4 to 6 times on a 10-14 days period, salts/nutrients should be sent out of your medium. To ensure this operation is working, you can use a TDS/ppm-meter and check the runoff values each time you flush, you should see the EC decreasing each time you water. Once this value has dropped close to zero, nutrients have effectively been washed out of the soil! Hope this will help, keep us up-to-date and enjoy your harvest :facepunch:
