A little more than I’m willing to learn to use lol. Don’t mean it’s overkill. Just more to keep up with and manage. But to each their own right! I’m sure you will have great plants in the end! If not. There is always next time. My current grow is my next time lol. My first grow made it to harvest but barely. I waited until halfway through flower to break down and buy a ph tester. Those poor plants…
Things are on a much better track this time.
Have to ask about the syringes in the bottle tops. I want to be able to put them through the tops of the liter AN bottles. Be able to tip the bottles to fill the syringe without having most of it on the floor. How do yours work?
If ever you want to buy a reliable ph tester this is what I’m using. I bought 2 because I learned the hard way going without a pH tester was hell.
WARNING do not drop or test hp ppm at the same time because it will break the ph tester accuracy. My plants had to tell me my ph tester was broken. I had to use the paper ph test strip and let me tell ya that was hard to see.

I used to run my ph at 5.5 now I keep it at 6.0 to 6.3.
The picture below are the plants I ran at 5.5ph

There’s a tube inside that goes right to the bottom and The syringes screw on.
I also use these. Makes growing so much easier.

My room was 4 by six I’m really occupying only four by five of it I have a 4000 Watt side King it drove 800 watts from the wall I have a 6-in ventilation system and I use CO2 generator I’ve been growing from my clones I’ve used Fox farm nutrition I run it pretty hard I think it was my problem is that I got tight buds and like four or five weeks in the flower and then I’m thinking it’s done that I’m cutting it maybe I’m going to let this next batch go 8 weeks of flour 9 weeks of flour

I have a meter that looked very similar to yours. Mine is made by Dr. Meter. I’m guessing Mine is just a cheap China company that has changed their name or copied someone else.

If you sometime notice a name or company, part # anything idetifiable for ordering that would be nice. And easier than rigging one. Thanks, love the idea
You have to use your eyes to determine when to harvest not a calendar. At a minimum use a 30X jeweler’s loupe or something with decent magnification and look at the bud’s trichomes. The auto pictured above flowered for almost 12 weeks. It could have gone longer but it wore out its welcome.
This is photo of trichomes from a northern lights I took yesterday. Its 54th day on 12/12 light schedule.
The trichomes are clear and cloudy. When they are mostly cloudy with a few amber, it will be ready for harvest.
I just like this photo
