No pix yet as I dont have a cam,no idea on temps either but, i had my bulb a lil closer (abt 1.3ft) to a single plant I have and noticed since that, a little more yellowing of the lil guy.Now the lil guy has been doing alright right and pointing upwards since I brought the bulb closer but its just the yellowing that's throwing me off..will try to get sum pix soon
