In Deep Water Culture (DWC) the water ph needs to be within the ranges of 5.5 to 6.5 and 5.8 will be the most optimal. The PH doesn't always stay at 5.8 though, it can drift, swing, fluctuate on a daily basis or it can literally change immediately. In the past i always chased my PH and adjust it to make sure it stayed at 5.8 but sometimes this can be tedious with having to raise or lower the PH multiple times a day in my hydroponic system. I stopped adjusting my PH and just let the plants do what the plants do. Ever since i have not had to adjust my PH or even check it because my plants remain looking healthy. You want to make sure that you stay within those range still so you may have to adjust occasionally but as long as your in range just leave it be. If your PH rises too high or goes too low then that could be a sign that something isnt right in your reservoir and it could be due to a nutrient imbalance or some sort of additive. you can try leaving the ph alone whether it rises or drops and see if it stabilizes after a couple of days. common questions in Deep Water Culture Hydroponics relating to PH levels. Do air stones affect PH? why is PH rising? why is ph dropping?
#DWC #hydroponics #garden #deepwaterculture #hydro #plants #howto #tips
I start with 5.5 and let it rise to 6.8. While keeping an eye on 6.8 because the plant won’t absorb if ph is to high so when that happens I re-adjust to 5.5 but advanced nutrients doesn’t require constant ph adjustment
I'm use advanced nutrients in soil, going too give DWC a try is the additives ok too run with the base nutes in DWC, I run the whole advanced nutrients line in my Auto pots an I have to clean the water line coming out of the res at least 5 times during the run!
I read about this..the fluctuation is actually good for the plants. As you know, certain elements are able to be absorbed by the plant at different ph levels. The flux allows your plants to get the full spectrum available to it. 5.8 is just the level where most elemental absorption happens. Great video as always Dusa.
Edit: if I had watched the video all the way through...Dusa states this ✊🏼
Exactly! And appreciate it fam
good news
Crap grows in the water. Infections... root rot... etc are a product of not lowering your ph... some tips to keep in mind.
1. Ph your water BEFORE ADDING NUTRIENTS. Wait two hours after adding nutrients, re ph down to desired level. And check ph once a day.
2. Do not use lemon or vinegar as su statutes for ph down. This is only good for a temporary solution until you get real ph down solution.
Real ph down solution has something called a buffer, which holds the ph down. Lemon and vinegar do the opposite of buffer. Happy gardening.
Thanks Dusa. Simpler has been better for me this current run. I’ll continue to simplify.
Makes sense. When I feed with coco, I alternate Ph every feeding. Feed at 5.8, 6.0, 6.2, and repeat. And I rarely have to go above 500 PPM in DWC since its efficient and nutrients are easily available.
fuck it, ill try it next run. not having to deal with ph would be worth the risk.
The water here will jump from 5.8-6 to way out of range. Up as high as 8. Not sure this would work in our area with tap water.
What did you do to fix this I have well water ph is at 5.6 from the tap but rising when nutes are in
Waiting for a answrt
@Bigxdal I wait 24 hours after I add notes to adjust ph now. Seems to work
was chasing it at the begining as wasnt sure how any of it worked,,,but yeah soon got on top of things and had stable tap water which helped,,,,,but would keep at 6,,,and if it went over 6.4 would bring back down,,,but by the end it worked out the ph would rise slightly,,,the would feed,,,,which would bring it back into range,,,,,only needed the ph down at res change overs,,,then plant and feeds kept ph stable without using any ph up or down inbetween only on res change over,,,but just ran into to some early root root so think i got it early,,,,brought out the H202 worked great last time,,,we will see how it goes,,,,but was looking great till now lol,,,,running a Bruce Banner f3 this time round
I don't really ph unless it's a seedling, after they start growing I leave it be and just occasionally monitor it, never really made a difference, had some yellowing, my ro water is at 6 out the sink, I don't even measure my nutes and Calmag, just feed some tablespoons every water change, managed a qp my first auto grow off one plant, it's not as serious as people make it out to be, you end up just stressing yourself out spending hours watching leaves grow. Eventually you grow extremely tired of trying to chase perfect. People say dwc is hard, it's not it's very very easy, soil is what is hard, you legit have to be there nursing it everyday if not it dies, I've left my dwc for a week, came back it grew and was normal with nothing wrong.. do that with soil and you come back to a dried out plant if your using high temp lights.
I use pool ph up and down for my outside vegetable garden. Never had any problems saves so much money. $10 for a bag I have used one bag for two seasons and I still have plenty.
My yields have tripled since i started to pH. So long as it is in a range that's one thing. Advising not to pH is not very good advice since you have no idea where someone's pH was to start with.
That’s why I said some people are going to have to adjust if it gets out of range. And that’s dope that yours tripled! But the comments are proof that a lot of people have also been doing this and having success. Nothing is going to work for everyone though
If you use distilled water and PH Balanced nutrients. Why mess with something that is not needed?
Now city water. You might need to adjust the PH.
You can take it a step further find a water filtration system that makes the PH the level you want.
Like Zerowater filtration system. Run any water through it it cleans up your water makes the PH of 0.
Then add your nutes and check the PH and see where it's at.
@@DusaFarms They've gotten lucky. A monster dwc like I grow swings pH rapidly and strongly. If you want pound yields off of one plant it's imperative that your pH is perfect. And your VPD. Both must be perfect.
use pro mix drain to waste use lighter nutrient solutions and rinse soilless mix every few weeks
@@MrCBeery a ph of 0 would disintegrate your internal organs on contact 😂
Didn’t work out for me!! Commented before I watched i understand what you mean 😊
pH swing is only a problem if youre running low PPMs , only every have issues with iron def with high pH with vegging plants with low ppm , in flower im no longer bothering to check flower pH
I AGREE! People need to realize that flying completely blind isnt what anyone will advise and isnt what he's saying either
Well my tap water is very alkaline, it sits on 8.0 pH. I guess most of you are using RO water which would explain why your pH swings are still within the safe range, but I have to use pH down to keep it in the 5.5 - 6.5.
Same, mine sits around 10
Yup, some tap water is extremely alkaline. Mine fluctuates throughout the year. In the winter I usually get around 8.5, during the summer it's usually a bit better at around 7-7.5.
mine is at 9
Love the video, and some great information about pH, I use Advance Nutrients PH Perfect, not had one issue, Thank you for all the information you provided to everyone, lots of RESPECT FROM THE UK 🇬🇧
Appreciate the support fam 🙌
Dropping one early
Had to look out for the UK fam
Thanks you so much for the info a lot less stressful plants are looking great
I noticed when I set at 5.8 or any range my pH always would raise a little to like 6.1/ 6.4 so I thought 💭 I’d try one plant and set the pH at 5.2/5.3 ,,,,rechecking the pH it would be right at 5.8/6.0,,,,I’d forgotten I was doing that and after going back tru photographs I’ve taken of past runs those plants where much bigger n healthier than the ones I’ve been running the last two grows,,,,=OLD BUCKETS LEECHING NUTRIENTS USECD EATS THE FIRST FILM LAYER INSIDE THE BUCKETS !!!!!!!
Go buy 1 or 2 NEW BUCKETS N AIR STONES and compare to the other plants ,,,today I bought all new buckets after reusing the same buckets for years!!!! My plants pH is back to being set at 5.3 ,,,,same nutrients as before same water 💦 and my plants are back to being BIG HYDRO PLANTS ONCE AGAIN
What if I use food grade buckets?
I’m on my third grow no ph pen. Besides these are outdoor plants anyway and God don’t have a ph pen that I know of.
If you pH it to 5.8 after adding your nutrients it should be good for a week. May have to top off with 5.8 water during the week but otherwise that's exactly what I do and I've never had problems.
@@neilsunstrum933 your ph will not fluctuate much if you are feeding the amount of nutrients the plant is taking up. if you are light with the fertilizer then the plant will suck up most of the nutrients in the solution then your ph will rise significantly, not because of bacteria growing in the pail or nothing like that it’s just that the plant is sucking up all the nutrients making the ph rise.
Meerweeeeeeeeeegaaaa! Thank u for this vid!
Subscribed 😮
Thank you for this vid man!
Just got a new subscriber!!
Like your videos. I have 4 DWC buckets going right now. How often do you have to add water to your buckets ?
By the time I hit flower I may refill aroumd day 4 just a little to last another couple days and then do a complete water change
Thank you DF!!
I have never pH to my water and I have a healthy looking plant if it isn’t feeding time I just add freshwater to it I do a feed once a week .
I run a four plant x 13 gallon + 5th 13 gallon bucket reservoir - PA Hydro. The first three weeks of veg show the pH always creeping high. I chase it twice per week. Then during the fourth week the pH drops below 5.0 and I chase that twice per week. Meanwhile, plants look superb. Last couple of grows I ignored the pH and things turned out fine. Lesson: don't fixate on the numbers - watch the ladies.
Wow! I'm new and feel i'm wingin' it LOL, my tap water has a pH of 6.31, my RO system has a pH of 5.53... and my RO water with nutes has a pH of 5.78! Fingers crossed I keep this going. I'm a new sub, gorgeous sincere eyes, thank you for sharing your knowledge :-D... I adjust my pH with lemon juice working on the baseline of my RO system, which isn't a whole heap of lemon juice. At the end of the day, plant health is the main indicator and trumps pH levels imho.
Stay away from using organic acid and base, I was using vinegar and it put a thick threadlike gel stuff in my res. Was a PAIN to get clean!
a @SLIMMY93 I used the smallest amount of white vinegar to bring pH down, I brought it down too much and ended up using bicarbonate of soda to bring it back up. I was doing this with a 4L jug. A month now and no gel type substance at all. Too many variables to discount it completely. So far it is working for me. I didn't want to use pH UP/Down. So far white vinegar and bicarb is working for me off tap water. We have good tap water in Canada. Even better through our RO system, but i'd rather use tap.
@@ln3527It will happen to you. Organics and hydro are really hard to maintain, but do you playboy!
Love the video never done DWC
I do soil all the time all organic never really worried about the pH is low as it was between 5.8 and 6.8 I was good
And whatever works for you might not work for somebody else . Right on ❤😎
Older video, but 100% agree. I change once a week but I only grow a couple at a time. That said most of the people I physically see using DWC, depending on the strain, go 2 weeks with nothing more then adding water. They do use that reverse osmosis water though.
All that being said, the video out lined the number one issue people have: Worry to much!!! Keep in mind this stuff grows in the wild and most illegal grows are just outside. They don't PH shit and don't use anything as far as nutrients etc. So just chill, keep an eye out, but leave it alone!!!!
I stopped chasing pH a while ago and realized I had less pH swings when doing so. I pH my water before adding nutrients and then maybe a small adjustment once in the system but I've noticed the same as you. It will swing!! But running an RDWC system my ph will also sit within a .2 range for a week or so. I went from checking it everyday to every few days to make sure there's no issues.
Thanks for creating and sharing bro!
at 5.8 are some things not good avlible u should go for 5.5ph and 6.0-6.2 for later flower.just around 5.8 are the sweat spots. Btw there are some nutrients that are very ph stabile but even with perfect nutrients i got serious problems if the envorment is off. The envoirment can couse bad metabolism and that influence the nutrient uptake. Sine the nutrient uptake is differnt from what the nutrient producer expected the ph will fall or rise in a matter of hour some times. I learned this by exident with some vegetebles. Befor i was growing under 100% perfect conditions and never got this problem. I am glad that i tryed some differnt things. The goal was to use a very low amount of energy. The experiment failed :D
C02 injection can also make even bigger swings with PH. Most people with planted aquariums would already know PH drops at night in general and when you add C02 injection that PH drop is even larger so id expect DWC would be the same. Between my Aquariums, Aquaponics and Hydroponics systems I only change the PH of what I'm adding to the existing mix or fresh fill's ;) Morning reading of 5.9 would swing to around 6.2 by late afternoon with a low of 5.6 lights out (NO C02 injection) expect more change with tank C02 ;).. Never used the trash c02 bags so unsure if they would effect much compared to regulated tank injection which does more the more C02 gets into the water from gas exchange during water agitation. Added edit = info on high tech planet Aquariums can show you so much about water and what PH changes to expect with x=amount C02. Once you get your head around it you can closely predict the change via amount of C02 in the water column.
Didn’t know that about CO2. Appreciate it fam!
@@DusaFarms Yeah killed a few fish in my teens 20 odd year ago when I 1st added C02. Couldn't work out why only 2 of 12+ breeds only died. People having major PH swings in their grows could be getting high amount's of C02 into the water column or just running shit nutrients ;) . could run a cheap ass aquarium C02 meter in a res to check when raining tank C02 in a grow
Brothers for life thank you thank you
Definitely good video, as always great content
keeping the ph in the range from 5.5-6.5 keeps the plant absorbing the maximum amount of nutrients it can. if you let it get out if that range, sure your plants will still look good but they won’t grow as fast. It all depends on how dedicated you are to your grow. There is an old saying that is as good as the day it was first said “ You get out what you put into it!” You can use gasoline in your car that’s been sitting for years and it will still run but the octane in it will be very low and the performance will reflect your choice if fuels. if you run premium gas with 94 octane it will run better and the performance will be much better too. Enough said!
I do suggest if you ever switch nutrients, to monitor to make sure. Your nutes may have some type of ph adjusting agent in there.
For sure. Monitor regardless just in case it does get out of range
@@DusaFarms ya thats a good idea.
thank you !!
very important information ,i was tired to chase that ph
so glad I found this video
Whats with the advanced nutrients products which regulate PH themselve ? Do you have PH issues there too ?
Dope video! Thanks
Thank you brother . This explains everything 🙏🍺
Thank you for watching brother 🙌🍺
Agree with you 100%, But you must control pH level when plant is small and have smalls roots because easy to get chlorosis problem, and block nutrition, leafs start be brown -yellow colors, and plant can die. I almost lost 2 plants in dwc from chlorosis, but quickly change to pot with coco and they alive 😊
If you own an above ground pool, you know that vinyl will make the pH go way high. Check your buckets.
Well I have not had such luck DWC. My PH falls low during week 4 and beyond in 12/12. I have been using the 5 gallon buckets. I was thinking maybe I need a larger reservoir to control the PH better. I have grown using organic Pure Blend Pro and chemical Advanced Nutes. All the same for me ph falls to low around week 4. Only hydro grow that I was able to manage ph was when I used an external reservoir outside the tent and use gravity to feed the plants. The system was called AutoPot Easy to grow.
I do have a mater plus ph up , down but i never used them , my plant grow very well without checking or adjusting .
i only act when it drops 1PH down in 24h, then i just change water or drop some h2o2 into it never chase ph when going up or down only 0,5 a day, plant also release stuff that changes ph and ppm so ignore slight drops and do your weekly water change...
So just to be clear you do pH your nutrients when you first put them in right? And then you just monitor it within that certain tolerance?
Correct
Great video !!! So much help I was getting so tired of chasing that PH EVERY day.
Appreciate ya for watching fam!
Hello I need help please! I try DWC 4 the 1 time. And I just take the plan from ADVANCED HYDROPONICS OF HOLLAND and didn't take a pH meter. My water is good at 5.5 and I thought it's easy but my first real leafs are dryed out and even brake. Can I do something? I s there a nutrient for Hydrophonic which don't need a pH regulation? I am ❤desperate cause I thought like he Say it will do his thing but it went wrong can I rescue something??
I just assumed my ph perfect nutes was fine and come to find that it wasn’t fine and the bottom leaves were getting ate up. Adjusted the PH down at like 2 am, I found it at like 8,8.5. Next day at like 11 and the ph raised up a bit again to 7 after being adjusted down to 6.5, so brought it back down. Gonna be checking like mad over next few days
Thanks bro. I needed this video
When I started growing at like 14 I never checked ph on my first 4 grows just used flora series with tap water and never had a severe issues
i get my ph down from Napa auto. battery acid is just sulfuric acid and is like 15 bucks for a gallon. GH charges 15 bucks for a quart of distilled water with a few table spoons of acid.
All fluctuations and all plant temperaments need this fluctuations. It's good stress :)
I understand that the plant adjusts pH by dumping hydrogen ions from the roots to suit themselves. Just put it within range.
I have a question my ph starts dropping late in flower on every grow and still drinking water are they finished or not hungry anymore
Maybe can get some advice from ya ? I went and set the buckets up again in a different room so I can sleep lol now PH ! Ye my ph is rising I’m using a ppm of 400ppm advanced nutes perfect ph technologies the whole schedule, I’m using x2 buckets half full they hold ten litres with abt 2-3 inches space from the net pot to the water surface full they hold 20 but the water will b half way up the net pot ! So I’m using ten litres per bucket per plant the ph is drifting from 5.5 I set it at as I know it drifts up 48 hrs later ph is at 6.8-7.4 plants look fine and healthy there just new cuttings two weeks into there veg cycle roots are white and then brown under the water not root rot it’s nuts stain temps are lo with plenty air flow does that soy d ok should I chase my ph if it’s at 7 + and the plants are healthy ???
Hey brother good video. I've got a question for you. How do I do water changes in dwc if I'm scrogging? Not a new grower I've been growing for 15 years but I'm trying out dwc so id like to know how I go about water changes while scrogging.
Invest in a battery powered siphon pump, you can get at Walmart for 15 bucks. All you have to do is crack the lid and you can remove old water into a empty bucket and then transfer your fresh water and nutrients right back in with never having to hold your plants up or remove netting! I just found this out and it’s so much easier on the back and labor!!!
Sit yr buckets on a pot riser, drill a hole into lowest part of the wall of the bucket an install a small tap or hose with a valve. Let gravity do the work.
I heard a theory recently which makes sense, but fungus in the air pump. Also low ph levels also cut into the plastic of whatever you using. Makes sense
I only ph on top off mix or when I switch out the reservoir completely after that it is what it is and mines worked fine so far
i have a question i'm using mega crop organic fertilizer and my ph goes up the next day from 5.8 to 6.4 is that normal for organic fertilizers to increase your ph like that? i think that might be the problem but i don't wanna switch to an non organic fertilizer should i just leave it as you say?
good info 😎
Facts ,, I'm with you on PH chasing
Peeps gotta chill don't chase PH as ole mate said let the plant Do what it does stress if it jumps or dives down. Stop over thinking stuff✌🏼
My PH skyrockets to 7.5 every 8 hours what can I do about this? I am chasing my PH 3 times aday but the plant looks like the healthiest plant in my room what can I do about this I cant find any videos on this usually it's only a little PH raise in their set ups my shoots up. over 2ph
You might have bicarbonate in your water. Carbonic acid-bicarbonate buffer’s around that pH and when you lower pH, over time, as the carbonic acid becomes water and carbon dioxide, bicarbonate will push the system back up to the buffer equilibrium at pH 7.5.
If that is the reason then the solution might be a stronger, di/triprotic, inorganic acid or a different water source.
@@gerttopmuller hmm thanks ill look into that if its possible
Very true!!
Thank you kind sir
People overcomplicate DWC. Great video.
Is you talking about soil or hydroponics?
I'm lost
Thats what I'm talking about!!! On it just started Dwc , let it ride
What’s your thoughts on using rain water?
I personally don’t use it because I don’t have a collector but I’ve got a couple of friends that use it and they love it
thanks man.
Yo Dusa what camera do you use to record looks crispy
Logitech c922 and appreciate it!
Excellent
dusa how do u get more terps on dwc
Make sure you’re getting enough light and some strain are going to be more terpy than others. I’m no expert but light really made a huge difference for me as well as the rest of grow conditions
@@DusaFarms ive definitely followed VPD to a tee, light i think is suffcient at 986umols/m2 do u use mammoth p, orca or tribus?
No I’m currently running Athena and before was running General Hydroponics
You still running Athena?
pH swings indicate an imbalance between the uptake of anions and cations in your nutrients. Without a stable pH, your EC readings are useless. You are basically running blind, not knowing if your nutrients are the correct ratio or concentration.
The plants tell you what to feed them by changing the pH and EC. Knowing how to read these changes helps dial in your setup and boosts yields and quality.
I usually get 2g per watt with a good yielding strain.
So what if its climbing to 7.8 daily in seedling stage
im new at DWC and i was a #phchaser lol TY
I really gotta switch my water on a weekly basis ?
Brother thanks for stopping me chase ph first time doing dwc now u got me leaving nature do what she does respect keep it up big luv from the uk
if it keeps going down. I'd be looking at the root rot
Hey bro have u tried Cana nutes for dwc if not u should try it Cana will not disappoint u bro
Okay for sure I appreciate it! I’ll have to check it out next run. I was leaning into trying advanced nutrients
@@DusaFarms Canna is great and holds quiet a stable PH BUT like anything more C02 in the water column will create a higher swing in PH between Day/Night cycle. Something I only watch for when running planted Aquariums with tank C02 injection since sure the fish may not mind the higher C02 in the water column for the plants BUT some may die after a few weeks due to the stress of the higher PH swings... Most plants/fish have no problem with the swing of PH from day/night cycle since its just nature.
I use Mantis buffered nutrients and haven't checked ph in yrs
I would say the same with soil except you wouldn't ever use a ph down product when you water.
I have tap water that runs close to 8.0 and have to use PH down to get it in range before feeding the girls. No issues.
That's probably unhealthy to drink. Tap water should be close to nuetral.
@@timm_3r Hope not because I've lived in this house for 22 years... It was built back in 1922.
You may want too send some samples to culligan and see what's in it. You could have sediment in your pipes making it alkaline. I would use distilled vinegar to ph down instead of the chemical water treatments.
I'm peein' on my plants, dousing them with vinegar and sprinkling them with sulphur and egg shells, soaking them in black strap molasses, worm castings and bone and blood, checking the ph every watering... it's turning into voodoo down here. 😄
My ph is at 7 from the tap so I adjust overall water to 6.0 and let it ride
Reminds me of the BBQ hobbyists that insist you need to smoke at 225deg and no other temp...🙄
😂😂😂
But dud they gone up to 7.8 in my satiation so ,, is that okay .. everything is okay actually
If i dont adjudt my PH every day, it will sneak up to 8 or 9 sometimes. Its a constant struggle. It doesnt co.e back down on its own at all
6.0 is perfect
Or should I just run it a whole week without ph ing n see where it’s at In a week n if plants stay healthy then fuckit it’s cool ??
I would say do this for sure. Just check time to time to get a feel for it.
Hey ma man so it’s great news man my buckets r running on advanced perfect ph nutes I left the ph for the whole week and watched the ppms drop as they consumed the feed I topped up with fresh water midweek. the ph stabilised at 6.5 and it just stays there man or there abouts I’m using beneficial microbes to protect me against root rot and there is no sighn of any root rot at all the plants are taking over everything there abt 2ft tall n bushed out as i topped em ! running 1000ppm advanced ph perfect nutes the girls are adults vegging that will rise to 1200-1500 ppms in flower these ppms are Perfect they are going crazy I’m no longer adjusting ph just letting the microbes do there thing everything is awesome with the dwc oxypots the microbes and plants are setting the ph at 6.5 ish and steady there growing up with no problems happy days well chuffed super easy 👍😉👍💥💥💥
💚👍you killing them with your love.🤣👍same thing here, ph once✌
💚🙌
Ok look people. If you used distilled water. You would never need to fix the PH.
I use PH Balanced nutrients. Which never messes with the PH and my plants are happy.
Youre not my dad lmao. Brings me back to the days of that meme.
I lower it to 5.5 and let it go up to like 6.3 and bring it back down.
💯!!!!
If you’re changing the water once a week, then you don’t have to ph, but checking the PH twice a day that’s obsessive. Once a week seems more than necessary; most people do 2 weeks or a month AFAIK.
I only ph when I make the reservoir.
That hat is killer!!!
Aye appreciate it!
Never used it my plants are just fine is just for luxury
