@Prom will check light specs and measure light distance tonight, just for in case. Should be about 30cm away.
For now while I still don't have a soil ph probe, I will do as @Mambawana suggested. Good thing I read that part about not flushing, just in time, only for a bit of run off to get an idea of what's going on in the soil. Got my water at 7ph, will post everything tonight, only get home at 6.
Got the bluelabs ppm pen too, wil get the ppm of the run off, think it shows the ec too.
I am really appreciating all the help guys, thanks!
