Grow Vlog – How to FLUSH Your Cannabis Plant Before Harvest



Yes, I’m posting a controversial video. I realize some growers don’t flush because there isn’t any scientific evidence to support it, but I flush because I can tell a …

  1. Could you run a load of none ph'd water until ppms come down and then do a regular feed if you have a lockout? Instead of ph ing all the water, I'm thinking of just running a bucket full of water through it in 1 lot to really push out the nutes, and at the end just a regular ph'd feed. Would this be an issue?

  2. i hammer em before the flush i always burn the tips just a little bit, but it always seems to work out being on the bleeding edge of nute burn, i can always dial back and its always at around HALF of what the Mfr recommends

  3. I happen to be doing a first flush of my plants this morning. I'm growing in 3 gal cloth pots with Fox Farm Ocean Forest. I've been trying Advanced Nutrients with this grow and have been getting good results. The way I flush is to put a pot in my bar sink. I start with a gal of ph filtered water mixed with some Flawless Finish. Because the cloth pot stops up the drain, the water fills up in the sink. I'm able to check ppm at this point. I lift the pot to drain and then use a gal of ph plain water. I keep alternating the flush until I get the desired ppm read. I didn't properly flush on my last grow and I could taste and see the difference. I'm a believer in flushing.

  4. 😆…when 🤔 u dumped tht run off 💧 water into the tub 😒…i was like noooo!…😆…my soul says feed tht to some other plants…like okra…cabbage…etc….😆..great vid and great job though….1

  5. I think 190 ppm is too much on the low side here considering water from the tap will be at least 100ppm anyway. You still want to leave some level of nutrients in there about 500 to 600 so over that two week period the plant can eat up what's left in the medium, otherwise you can really starve it far too early. Just keep checking the water run offs if unsure with a decent ppm reader

  6. Great advice bro…i used to do this back in the day when i grew smaller less stinky plants…these days there's no way i could move each plant into the bathroom, it would simply stink out the whole street..saying that i still use this method, somewhat adapted as i grow in my attic…i still drown the crap out of em but my pump does all the work in removing the runoff via a hose to the bathroom downstairs..works for me and more importantly works for the plants….keep up the good work, happy growing
