Glossary of terms etc

I am new to Pulse and everything it has to offer, but I would love to learn and understand everything that this sensor has to offer. Is there anywhere I could get a glossary stating what everything stands for? also what is optimum light spectrum, co2 levels indoor or in a greenhouse. I have been planning a grow for almost 3 years now more as a hobby than anything, I have read many books and have climate controllers, Co2 controllers, EC and PH controllers, peristaltic pumps, water cooling, hopefully good lights., anyways trying to do a closed loop system with a couple plants to start and then increase from there. I bought pulse pro to help me explain the unexplainable, it’s a sensor outside the box. (Well inside)

We’ve got a pretty extensive user guide here: Ultimate Pulse User Guide | Pulse Labs Help Center
