Please bear in mind I have very limited resources.....  The only equipment I have right now is a 2x4x6 marshydro tent and LED light as well as the air exchanger with a temp/humidity sensor that by some mysterious and as yet ascertained method controls the volume of air exchange.   I need a list of absolutely must have sensors and devices to measure the various environments and nutrients conducive to primo bud.

I'd say that a reliable ph meter is even more important than the EC meter. If the ph is out of range, there's no telling what can happen. Also something in your tent than can read temperature and humidity. Your fan controller might do that. My AC infinity does a great job with both but a stand alone cheap thermometer and humidity gauge is fine too. It's nice if you can read the values without opening the tent too like a remote readout.

Never used a ph meter in my on & off 15 years of growing but again my water is clean with low ppm, ph around 7 and always organic fertilizers.. Only once had a bad batch of soil that was over-wintering outside so it got anaerobic.

The control panel on the particular air mover I have has a probe that goes in the tent and the readout is mounted externally.  It measures RH and Temp. However if my previous failed run is any indication I'm gonna have a  huge problem maintaining humidity and temp at acceptable levels when the lights are on.  I've accepted I'm going to need a humidifier but the runaway temp with lights on worries me.

Sounds like the AC infinity Cloudline controller I have. The temperature and humidity readings are great and those are programmable to maintain temperature below set maximums. Took a minute to figure out the programming but works well once in the proper mode with the right settings.


PH pen must have First You can buy cheap ones for like 10/20 dollars . Also some pens do a combo PH removed link Intake fan or you can just use your extraction with a passive flow. Change the time of day when lights come on to the cooler parts of the day.
