just wanted to verify, after going through various cheaper versions of pH pens, that although the initial investment is high, this been working well for 18+ months now, have to do the occasional calibration, but its still going strong, and I would recommend this product if you need a pH pen

this model is also the model we recommend, Don't buy cheap, in the long run you'll spend the same amount, one good mterer, or many shit ones.

True in my experience bro! Hard to afford all the good stuff all the time though, sometimes you just gotta do what you gotta do ?

Hey. I just bought both the ph pen and the EC reader from Blue Lab. I figure, better pay a bit more and get something more reliable and accurate. I just got them a couple of weeks ago, the problem is I never owned a ph or a EC reader before so I don’t really now how to use them.?

You just dip them in the water mate, wait five to ten seconds and it will give you a reading. Adjust accordingly Smile

If you need any help, you know where you can find me Smile

When I get home from work I’ll try to see if I can do some reading with it so I can start getting familiar with them. 

The weather is still a bit shitie here (welcome to Canada were there are only 2 seasons in  the year, WINTER & summer). I didn’t want to run a heater but I guess I don’t have a choice if I want to start my grow this Saturday. Temperatures are still below zero at night.

Ruuning your light over night will help mate. in the veg stage you can even run the lights for 24 hours, that will help with temps.

Have fans pointing down, and intake at the top of the tent, with out take at the bottom. This will encourage the warmer air from the light move down the tent. you'd be surprised at home much heat it will actually give off.

No mate, you can get a bottle of the stuff pretty cheap. You only need to calibrate once I grow, they stay accurate for ages. Once calibrated, throw the liquid away and use more next time Smile

I’ve had a lot of people come in who stir their pens in their solutions.....don’t do this, the probe needs to stay still to be accurate. Make sure to clean too as this will prolong the life. If you have the blue lab guardian or combo, than your ph probe needs to be replaced usually after six months.  Buy the storage solution too.  Keep all the stickers and boxes if you want warranty.

Blue Lab PH pen is the best one i've ever owned. As long as you take good care of it, it will last for years. Might be a bit pricey compared to other meters, but much more reliable for a longer time, worth every penny

Totally agree! The pen is awesome,it’s the probes on the guardian and combo meters that only have a 6 month life span. I use the blue lab pen too with a hydrotester ec pen. This one guy came in and his was 7 years old but I couldn’t fix it, so as long as u take care it can last. I don’t know about Europe but at my store we calibrate for free if you bring it in and do a test to see if your pens n probes are still in good condition.
