Water - what amount and how often?

soil type water and ph meter probes are notoriously poor pieces of equipment. they don't get much love on this board as they can vary crazy between them, and no two growers use them exactly the same way.

very few soil growers use them as a result, even fewer here will recommend them. longer term most learn to grow by a read on the plants.
I don't know if you know of the kind he's using? You're thinking of the traditional analog ones, they don't work at all in terms of pH. Blumat and Bluelabs are very reputable and the best kind of pH meters are soil meters that you can use for both soils and solutions.

They cost a little more but is easier to use in deep reservoirs and the only ones you can use for soil like mediums.
 
The meters keep things consistant


so long as the grower is consistent. newer growers rarely are. no one is at fault, it's simply the learning curve.

i'm well aware of blue-lab etc. it's not the tech level of the instrument that is at question. it does bring up the issue of affordability, as most new growers won't know the difference, and generally just grab something generic from either a big box, or hydro shop.

most new guys buy based on how they think their wallet feels. this puts them into a lesser instrument off the bat. most of those generic green probes won't even agree with each other when used side by side in the same pot.

agree that if you are going to use one then don't cheap out.

as an alternate you could watch your inputs, learn how to water a potted plant properly, and learn to grow with a read of what is happening to your plants, all of which are skills transferable to many media types, and not dependent on a probe.

i don't knock anyone who wants to use them. i used to have a couple lying around myself, they quickly fell into disuse. forgot i had them by the time we ran the larger promix grows.
 
It's all good @bluter I just don't like to guess if it's a 50/50 I usually get it wrong ,casino's are full of folks who like to gamble I'm not much of a gambler anymore those days have long past!


i'm ok with that. it's just not a tool i find necessary or would recommend a new grower becomes dependent on. none of the local soil and promix growers i know use one. several have them though, they just don't find them needed is all.

I agree with this sentiment. More often than not new growers get themselves tripped up and concerned with readings they’re barely understanding to begin with when they could find much more success focusing on gardening basics. Proper containers, aeration, proper watering, feeding, etc.

I’ve found the numbers on meters consume new growers minds and blind them to other factors. Now, if you’ve got some experience either growing or using the meters for measurements in other stuff that’s a different story but trying to figure out PH and TDS for the first time, AND trying to learn to grow cannabis can be overwhelming.

A tool is only as good as it’s user
 
^^ What @Keffka said
I barely use any metering devices, but I have done in the past and now read the plant instead - far more accurate
Does it help if all your meters say great but the plants look shit? No
:hookah:

Agreed. However I get what @seaofgreen18 is saying, especially with the operation he has going. The meters can definitely help you keep unwanted stuff out of your grow and keep an eye on what’s happening, but this usually implies you already have a very strong handle on the basics.
 
Ok I'll give you guys that one all's I'm saying is before I got the good meters I'd have issues more often and than not indoors, up and down yeilds and quality after I learned all the other stuff like you guys say it got way better
But after I got the meters once knowing all the other things it made it way more consistant and it costs me way less on inputs with those 2 things not to mention my water bill
It's kinda hard to lift 200 gallons of soil in the bed to see if I need to water, one end might need water the other end might not or same with pH here it might be 6.8 6inches away it might be 6.0 so that's what I'm trying to say if no one uses a meter ok but I'm still going to suggest it because I still think it's a good idea like testing ✌️

Common sense eludes alot of ppl my plants say I'm good and my meters verify it these don't look like shit! I wasn't getting flowers consistently like this until I got those meters. Cut on 6/1/2023✌️

you should be consistently pulling that considering you are outdoor and in that climate. i'd be more surprised if you couldn't.

by now i'd hazard you could do exactly the same without the probes. again, i'd be seriously surprised if you couldn't.
 
So explain feeding directly after a good watering
What exactly don’t you understand? Flood conditions in nature happen all the time. The plant speeds up processing water so the roots can get 02. As the media drys out rapidly you then feed while the plant is in this this ‘uptake mode’. Vegetative growth is rapid using this method.

No doubt but I like using them it tells me before I get issues arise that's what I like about them and the flowers were inside grow I only use the pH meter outside at the start when mixing my soil but the blumat moisture meters stay right in the bed plus in the basement I use blumat irrigation inside with soaker hoses and carrots The flowers are from my indoor grow 4 plants I'm waiting to see what fall brings

I understand what you are saying about the flood conditions and watering to extreme run off. I was wondering how and when you feed after that. Could you explain your feeding regimen. Do you feed when the pot dries out again or while the pot is drying but not completely dry. Is it a basically: flood, feed, flood. When you flood you are just using water? And then when you feed, you don’t flood? What are you feeding? Explain your technique in more detail. Thanks.

Feed when you stick your finger in up to the knuckle and it comes out dry—there will be moisture below—so ‘as it’s drying but not completely dry’ —feed until you get ‘plenty of run off’ —Now let the medium dry out good—pot gets light and plants droop ever so slightly—now do it again..I water with plain water. I feed with jacks 20-20-20 /calmag 5ml/gal once a week in veg. In flower jacks 10-30-20 / calmag 5ml/gal twice a week.

There is no special technique or trick—EVERYTHING you do to your vegetable garden applies. I have a wall of sunflowers, green beans, tomatoes, peppers, big ass pumpkins and I feed everything the same—as fruit starts to develop nutrients are switched to 10-30-20.

just keep it green till harvest—unless you’re growing purple or blue genetics—if it’s colorful it’s sick!

Ok. Thanks for the explanation! Your garden looks great!
