Bluelab pH Controller Wi-Fi 24/7 Reservoir Monitoring for pH with Automated Nutrient Dosing, Edenic Integration, Replaceable Probes Safety Features Optimal for Hydroponics & Indoor Plants

Very consistent. Appreciate the high quality, precision, accuracy, and user-friendly-ness.

I wouldn't recommend this to someone just starting out. I would at least get an idea of how your system behaves first (maybe half a grow) and then grab one of these. With that being said this thing is amazing! I have two for two DWC setups and it saves me so much time. My PH always tends to drop. This thing keeps at a solid 5.9 without a blip. I was ph'ing my system 2x a day. Such a hassle. I haven't ph'd since I bought this. I wish I would have bought it years ago. Just set it where you want your ph, how many seconds of solution you want it to dose, and how long to wait before dosing again. I have mine set for 2sec on and 5 min off. Works great. It never overshoots. I can put it online but haven't found the need to. I generally don't adjust my ph to different points often. Nice feature though. My only complaint is Bluelab didn't make an option that offered up and down. I never have to ph down now, but it would be nice to have total control. I've run nutrients that sway up at first and then hard down later. If you know how your system behaves and you want more time for other things this is a great option. Plus plants enjoy a stable ph. Worth the money.

Checking PH levels daily in a hydroponic garden can be a pain. Missing a day can mean a ruined crop or reduced quality.I've hesitated buying this product because it is so expensive but I have to admit it is worth every penny. I regret not buying this sooner.My plants are healthy, deep green and growing robustly. No more checking PH every day. This device gradually keeps my PH levels at 5.8 without worry or hassle.Stop loosing quality and time with your growing...buy this now.

Pros:- remote access to ph data so you’re not always wondering.- added benefit of remote access to water temperature level in hydroponic system, again so you’re not always wondering- auto dosing to help control PH levels.- you can change the ph dosing settings from your grow-site laptop, this makes it really easy to tweak dosages without having to go into your grow room and mess with the controller.-great addition to my hydroponics setup where ph tends to rise after nutrients... this will keep dosing ph down until it hits my lower limit of 5.5, and then reactivate and pull ph back down when it spikes again.-nothing else on the market that can do what this does.Cons:- high price tag- you need to spend another $100+ on the connect stick separately. And then a laptop that’s dedicated solely to this device at home which you can’t remove..- you need to have a separate laptop that’s on 24/7 near the controller in order to be able to remotely view (but not control) the ph levels on mobile app (can not be in sleep mode, but you can still lock it - just make sure software is running and sleep mode is disabled on your comp).- you have to go through some trial and error to figure out how to have this provide control of PH. The dosing is not based on PH level (I.e. it does not read the ph level and bring it down or up, instead based on time and intervals). You need to guess what will keep ph in levels you need by monitoring data, but it will automatically stop dosing once it hits your limit. And if you have the connect you can keep an eye on it all on your phone.-need to recalibrate every two weeks.- cannot remotely adjust dosing with mobile app, you have to rely on internal setting to stop dosing if it goes outside of limits... but at least you can know when you need to go home and tweak it. And you can do so from the grow site laptop, without having to go in the room.- you can’t use both PH up and PH down with this at the same time, it can only dispense one or the other. I use mine with ph down to help control the ph of the resovoir in my hydro system, because the ph tends to rise and not fall.- you will still need ph up and ph down solution on hand to manually adjust if necessary. But at least you can look at the level in real time on the wall and no need to use messy devices and get all in the water.-need to keep grow site laptop fairly close to controller. Maybe within 20 feet.Overall makes managing a hydro system ph easier, but not 100 percent automation and does require a separate computer that can stay home and be on 24/7... plus extra ph up / ph down + good ph tester to help get ph in check if there are swings that this thing can’t control.. and if you’re away from home and this happens, you can’t do anything to change the dosing settings or solution it is using. Will need second unit if you want to ph in the opposite direction.

It was a bit tricky getting the unit dialed in to dose within my preferred range (trual and error on my behalf), but the ultimate issue with the product, for me, was the related app. Setting up notifications was the BIGGEST hassle. Multiple emails and calls to BlueLab, tinkering with my phone endlessly, etc. Very frustrating. The unit itself is silent so, when it alerts, it just flashes. So because the push notifications weren't coming to my phone, I'd either have to constantly check the app or go look at the actual unit. That completely defeated my purpose of not having to do that.The unit itself seemed to work as listed but, unfortunately, tge software/app had an issue that made the product useless to me. It's crucial to recieve notifications in my garden, missteps can cause set-backs or, worse, loses. Hopefully BlueLab/Edenic resolve the software issue to match their quality hardware.

I seldom give 5 stars. I gave 'accuracy' 4, b/c I have no way to verify the accuracy, but my plants are thriving like never before when I was trying to manage our hard water manually. Do follow the instructions for monthly probe maintenance (clean, rehydrate, calibrate), and you should get years of service from this simple well designed device. At worst, you may eventually need to replace the pH probe, at considerably less than the cost of a new pH pen device, which is essentially a disposable item (my Blue Lab pen was useless by my third season with it).
