Anyone NOT change their res?

[NeWcS]

Anyone run the same reservoir from start to finish? I have been running my dwc buckets and my aero this way for this run and am hating myself for dealing with it weekly years past. Every few days I just mix up a couple gallons and add it back into the reservoir. Seems to be a lot less work and thus far I've had no problems. Anyone else roll like this?

I tried to but ended up having to many deficiencies. Back to changing weekly and my plants look happier.

I had the exact same problem. I started getting nute lockout after about three weeks. Went downhill from there.

There are lots of elements that the plants will not absorb as readily as others and these will build up in the res causing major issues in later stages. Aero is not for lazy people.

I had root problems, rot and brown algae within hours of my ro res change. I let it run 4weeks straight as the plants seemed to reach a homeostatic state when I added the dwc tea. Mine are doing well, I just did a res change, with a 1/4lire of old res water 1/4 liter of new tea per 5 gallons. Added flora nova bloom. Total ppm@1500

Seems to me that if it were doable and not risky everyone would do it. I don't change it every week though, more like every 10 days, which so far seems to work out fine (at 5th week 12/12). By the time I change it entirely I already added half the volume over a week+.

my rez changes so far have been once every harvest... i have a rez for veg and rez for flowering. when it runs low i top off with x amount of gallons and add nutes for x amount of gallons. when i transplant out of flowering when finished with 8 week cycle i wash an bleach then start new 8 week with another cycle of plants.

mine have been healthy whole time. i have several air stones in my rez. mine is a flood/drain also though so all nutes are in 55 gal drum whole time with air.

Running a small UC setup. Last round I changed the res out once. This round, none. In week 7 of flower.

The only time I. Don't change the res is when I'm using a one gallon amount of solution. The reason is because the plant soaks it all so fast that there litterally is nothing to change, all the water goes into the roots, but then ofcourse you have to be refilling it immediately before the roots dry. If you use, an. Any method though you should still be wiping the res with towel before refilling. I recommend just about filling your res with water and nuts half way at all times, as the water level goes down every or every other day add more to get it back to half way but never over, then on your last day to two days don't add anymore before a flush. Then once flushed keep adding water daily to keep it half way. Personally I use a commercial 112 litters a minute pump with 5 air stones for my res so I have one on each corner and one in the middle so my water is very well oxygenated and I notice the water and nuts get soaked up more then when I had only one air stone with a smaller pump, so I fill my res to the top but unless you have a huge loud pump like mine I would stick to low water levels of half way to avoid changing the flush so much and wasting nutes.

Also add some h202. Right about a day before a flush. You should probably never go less then three flushes a month and never more then 4 to avoid wasting nutes and water and time.

Where is your logic? You are telling people to do unnecessary change outs just because?

 

[Malevolence]

I change my dwc buckets once a week once the roots get big.

I'm sorry you feel that it's not logical to do flushes aka change outs. Your right never do change outs aka flushes. Instead let months go by without changing the water ever.

As Slanty would say. Where's the logic in that? That's unnecessary. But I agree doing a change out once a week is a good idea.

I change about once a month, just because I'm feeling ambitious. The plants always look fine and could probably go without the res change if I was really dialed in on the nute refreshment. Just my .02 KISS

When people learn how to read their plants instead of a bunch of BS on the internet, flushes are totally irrelevant. Flushing is only required when people overfeed their plants because they are going by what they are told or read someplace, instead of learning how to read the plants themselves. Do what you want, but I prefer to keep it simple and cheap. I only do res changes when required. I have not changed my res since the first week or 2 of February. I do add 2+ gallons of water back every day and nutes when required.(around 40gal total for system) Been growing dank for 15+ years.

Glad to see there are some others that have some common sense around here! What type of setup are you running?

 

[Sativied]

Changing/refreshing the rez isn't necessarily 'flushing'.

And whether you 'need' to change the rez frequently isn't really relevant. It's better to change the rez once in a while to keep the nute solution balanced. You don't know how much of the ppm is NPK etc.

I change my RDWC every week, maybe 8 or 9 days sometimes but its really to keep everything nice and clean, i like to wipe down the insides of the buckets, clean the pump's filter. A fresh batch of nutes is nice aswel

Yes 70's I'm glad to see you have common sense like the rest of us aswell.

Hi Slanty, I have DWC 5 gal buckets and DWC 18 gal totes. If my plants had problems I probably would be tempted to change the res weekly, but mine go a month easily with no problems so I have no worries.
