This here and it was almost $70 cheaper! $125 vs $170 and this comes in sturdy box/case and has calibration fluid/ storage solution/ probe cleaners and electrode gel!

Bluelab has none and comes in this cheap ass box!

Probably how 2 bluelab came broken back to back being in cheap ass box with absolutely 0 padding!

How quick does the Hanna give you a reading? Is it a pretty consistent reading if you move it around the pot?

You want to ph your water to around 5.9 or so because your run off with coco will actually be slightly higher than the ph of the water you put in. So PH it to 5.9 so that your ph of your run off will be 6.3 hopefully. You may have to. To play with it for your particular environment. But typically speaking run off from coco is higher than the water that goes in.
Respectfully I disagree, my experiences with coco and I'm primarily a coco grower for several years, runoff ph varies considerably, and at times can't necessarily be changed by higher ph fertigating to get lower ph runoff or the input of lower ph fertigating to get higher ph runoff. PH runoff in coco is not a good indicator of what's going on in the root zone. I have grown plants where runoff which showed 5.5 no matter how many times fertigating at 6.4 to 6.5. And just the opposite, it runoff was 6.5 even though fertigation ph was 5.8. And the plants still grew beautifully.
In my experieninces it is not a valid indicator. That is not to say that your input ph should be outside of the 5.8-6.4 range. IMHO the only important indicator of coco runoff should be for ec/ppm. This is supported by several science based articles e.g. source Manix Botanics -

It’s fairly quick! I leave it for few minutes to make sure stabilizes but it has a lil hourglass that lights up if it’s steadily moving and once it goes away it’s at or just about at stabilization point! And ya it’s consistent if u move it around! Easy as shit to use too and works for soil/coco/rockwool etc! Can also use it to measure solution ph if ever have the need!

Bluelab probe on other hand not only is it a piece of shit but u gotta get calibration fluid to even use the thing….. then u need storage solution and u basically need a street cone to make a hole in the soil to insert the probe! For my Hanna I use a lil king palm packing stick to make hole for it!

That’s perfect. I have that Accurate 8 meter and same thing as the Bluelab....it’s like driving a fence post into the soil every time. I can hear it rip through roots.... I imagine not ideal.

Ppm is very important as well. But if your ppm is good, then your ph should follow. Ph is actually indicative if your plants will even uptake certain nutrients. And yes at 6.5 plants will still grow beautifully as you said. 6.5 -6.1 is the ideal range you want runoff to be as anything above and below you start to get nute lockout. 6.5 is the absolute highest you want your runoff to be otherwise you will start to see problems. But to say PH is not a good indicator is inaccurate. There are also plenty of scientific articles to support the fact that your plants cannot uptake certain nutrients if your PH is outside of a certain range. You are allowed to not place importance on ph, but I know for a fact it matters a whole lot from my growing experience alone.

Here is just one example where I checked runoff almost everyday and it was never above ph 5.5, 1/2 gallon pot coco/perlite and credit to breeder Twenty20 Mendocino Whiskey Zulu.

And in those pics, you can see curled up leaf ends and more some tips that are more tan than yellow, which indicates a slight burn or ph/lockout issue. Very healthy plant, but if your runoff was 6.1-6.3, your yields would be more impressive .

I had severe leaf issues on my last grape slurri I ran, buds were beautiful, frosty and unaffected, but come to find out my estimates on my ph were way off and that run. Now that I invested in a good ph meter. My plants are even more robust than they have ever been! Not saying you can't get good results outside of optimal ph ranges, just stating that your results can be improved by also keeping ph in the optimal range. Just because you don't get bad results.... doesn't mean you can't get better results.

I stay within 5.8-6.1 full run always. High 5's during veg is best and low 6's during flower is their preference.

But I'm going full autopot after this run I'm done with hand watering.

How was the grow on the blueberry faygo...? Did she lean indica or sativa...? As I grow bonzai style, I don't worry much about size but some of Roc's photos are bullies for space.
