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.

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

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.

I’m using LED’s so not much heat there.
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.
