I'm just wondering what do others determine the light brightness when growing.
I've always used a watt reader and thought if it's under 200w it's OK and never really thought of the power on the plant, that is until I started using a PPFD app on my phone and what I've noticed is I'm getting a great coverage of PPFD at around 500/600 at a watt of 80w.
If I thought for a second I'm only going to average 80/100g over 4 plants od be gutted!
Do anyone else obsessed over watt etc?
