Flushing Cannabis Plants



Note that I do not flush very often. Better generally to simply come off the feed just for the last few days so long as you haven’t been over-feeding. Here it is …

  1. im just about to start my first grow and I was recommended by someone to flush once a week. is this wise? how often should they be flushed? or if not to be flushed much when is the best time?

  2. only when salt has built up in the soil and is detrimental to the plants.. if you use good soil and light feed with good bio products you may not need to flush at all and thats the best achievment 🙂

  3. why do people flush at all? drying for 5 or 6 more days will ensure you get the smoothness of a flushed grow, feeding up to harvest will increase yeld and potency and i have only recently learned this so i am not knocking anyone who flushes, ive done it all my growing life until i found this out, im just trying to share the information. anyhow, has to be worth a look into for any serious grower. nice plants dude. respect

  4. TRUE…….I STOPPED WATERING THIS WAY. I WAS OVER WATERING MY GIRLS AND DROWNING MY ROOTS.

    NOW I USE lEES WATER & A CATCH BASIN OR ALUMINUM PAN TO CATCH THE DRIP-OFF AND JUST EMPTY THE BASIN IT AFTER IT FILLS.

    72HRS LATER…..MY DARLINS TOPSOIL IS SEMI- DRY AND PLANTS ARE GIVING OFF A SCENT THAT WOULD LIFT YOU UP AND BRING YOU HOME FOR DINNER.

    .KEEP GROWING FOLKS…ITS A MATTER OF TIME BEFORE ITS ALL LEGAL.

  5. I don't recommend flushing much at all to be honest brother. There was a specific reason here, 110 degrees temps giving me a rare salt build up 😉 We don't use tap water, we are off grid with spring water deposits etc so it's all fine. Cheers tho for the input, seriously, it's all good PPPP

  6. Personally i wouldn't flush like that especially if thats straight tap water! You want to flush slow and steady and try not to let water go down the side of thr pot because it won't be flushing anything. Let the soil dry out in between flushings and the amount of water, well I give it at least twice the pots size eg 6 litre pots 12 litre+ flush.

  7. Flushing basically just gets rid of the 'salts' that build up in he soil from the nutes etc Some nutes, non bio will build up higher salts. Flushing means the plants use up the last remains of food in its own pathways which in turn usually means easier dry,cure, better around taste and turpines 😉

  8. i dont even use guano as are certain health risks so I would be wanting horse manure out I guess too. even so, a goodflushing to totally leach the soil should still do the job. Use 3 x as much water as soil

  9. it depends on the feed and the individual plant. a strong plant with bio products doesnt really need a flush, its just fashionable to do so as it 'can' eliminate some bad tastes from harsh chemicals. On average I am taking them off food the last week and no major flush. (These were flushed cos v high heat gave poor soil)

  10. Im a little bit of a newbbie grower but when should you stop feeding it? Because i herd giving only water once it starts flowering is a good thing and a bad thing i never hear like one direct awnser always both so it makes being a first time grower harder>.<

  11. I dont always flush,depends on the food/salts build up, but generally the flush is a once only thing to remove this excess salt and then to finish off with just water and no more food. Thus allowing the plant to use all stored food which in turn can help the taste of the plant down the line 🙂

  12. In this case it doesn't as the water is delivered to deposit. However, altho everyone seems to have a fear of chlorine, less than 140ppm won't hurt cannabis growth whatsoever. In fact, quite likely beneficial in small percentages. If your water is higher in chlorine, just let it 'sit' for a day 😉

  13. That dirty tap water happens to be natural spring water delivered here by lorry by the 5000L tho unless you have very bad water quality unfit to drink then regular tap water is fine

  14. You dont always need to flush and the water needn't be exact ph if the flush is late. i.e using good bio products you can flush during the last week straight from the tap as I did here.

  15. …………….In a typical growroom with the right temps and some airflow they will dry out naturally without a problem.
    I stress tho quality soil under the right environment will rarely lead to problems

    Dont water til it runs clear no, just water slowly til you see tiny trickle of water. Keep that brown stuff its mainly nutrients 😉

  16. Hey amigo 😉
    Nowadays over-watering isnt so much of an issue simply because most 'quality' soils are very good and are made to allow the roots to breathe etc but yes particularly in seedling stage we dont want them saturated and then not able to dry. this would be made worse if they are kept in coolish or dampish conditions………………………..

  17. im about to do my first grow and this is the only thing im unsure about. over watering them can deprive the plants of vital oxygen and kill them right? so how do i know when to stop watering? do i just keep pouring slowly until the brown water becomes clear and leave it to dry for a few hours until i put it back under the light?
