If one were shopping for meters and such , check out apera.
I have one of there meters and it’s very consistent at holding a calibration and imho does a great overall job.
Ph, ec , ppm , salt if you have pool.

Enjoy whatever you choose.

Wow you guys reeeeallly love to selectively read posts. I already addressed that.
You base your feeds off suggested amounts of nutrients from the manufacturer. We get it. You still have no idea what levels those are.

You think an EC meter and an automated feed system are both optional equipment and of equal importance. Not to mention fertigating coco every other day or longer. And you wonder why you have issues. And you think your weed is better then a dispensary? Lmao.

I have a couple. I only use one when I'm mixing up something I haven't mixed before to see how much it takes to get to the target EC I want. Then I just measure and mix.

Same thing when I was doing hydro. I never checked EC after the initial mix and would just top off at half strength and then dump and refill the res after about 10-14 days. I would check the pH and adjust that every couple of days though. A TDS/EC meter only tells you the total dissolved solids not what they are.

Not my problem you can't do maths manually, and need to rely on devices for your numbers. I'm good bro. But thanks for puffin your chest for no reason at all.

See thats basically what i do/did, checked EC initially and have used the same nutrients and levels for 18 months.

I bought mine so I can’t start knowing 99.9% of the time of what I’m putting in. Because now I’m logging and charting on paper. Kinda tryin to create a recipe of success. I mean the things like 20-40 bucks on Amazon. Why not have one just to be safe I guess. Maybe it’s the amount of comfort you have in yourself and feeding practice.

I always mix up jugs of both jacks A&B in super concentrated batches first. I don't even pay much attention to how much i'm adding, I just be sure not to go over the max soluble limits for each part, and always eyeball roughly the same amount of scoops. I end up using up part a and part b about the same rate.

It's way to easy and i'm not sure why everyone still mixes and measures out their dry nutrients by volume/weight.
Yep, concentrated stock solutions are where its at with Jacks, so much easier to work with than weighing and mixing every time.
I just follow the 1:100 concentrate ratio on the bag for consistency and repeatability so I can mark my levels for part A and B on a graduated cylinder and hit my target EC without a meter.

Not tryin to sound like a dick. Just being honest. How do you know your hitting your target ec without a meter? The plant says “hey I’m at 1.5”. I understand if there’s nothing wrong you can only assume. Because I JUST bought one. I’m just curious how everyone knows their ec/ppm without a meter?

If you mix the same exact amount of nutrients per gallon of water then the EC will always be the same.

It takes about 3 minutes to weight and mix Jack's. I do it every 3 or 4 days.

It helps a lot, especially when you start or switch nutrients. I think all new people should use one until they get good at feeding. Another thing is, if you measure by volume it might vary over time if moisture gets into the mix. I think most of use could skip using TDS meters after mixing Jack's a bunch of times.

I do use an EC meter, but when it comes to making concentrated stock solutions, I follow a recipe so there is consistency and repeatability. If I pour out 200ml of Part A and add it to 15 gallons of water, it will be 1.0EC. and if I make a subsequent batch of concentrate with the same recipe, 200ml of part A will still be 1.0 EC. I dont need to sit there and watch my meter till it reaches my desired EC.
