Awesome chart @Niala
Thanks @Majiktoker , it’s just to clarify some false statement that at acceptable growing temperature and water the swing in accuracy with PH reading is not what is circulating (as much as 0.3 difference in reading)
If someone as a difference of more than 0.1 in reading, they should change there PH pen asap

Here’s a chart for LED lights, it’s for equivalent watt, so if your LED light is 300W follow the chart for it, it’s not made for actual or real draw and it’s an approximation, that clarify, here it is :
120 W to 180W ~1.5 feet
180W to 300W ~2.0 feet
300W to 600W ~2.5 feet
600W to 1200W ~3.0 feet
1200W to 2000W ~3.5 feet
Hoping that’s helping as many as fellow growers possible
