Everytime I use MH lamps I seem to get heat stress/hot spots.. even several feet away from a 1k halide.
?? What gives ?? Leave temp doesnt seem to get too hot...almost just as if they cant take the spectrum or UVs or something well.
I mean.. I'll still get noticeable scorching several feet away whereas the HPS I can put within ~1 Ft.
they run hotter plus the mh bulb shape creates focal points. i think if you kept the bulb moving you could avoid the burn while keeping them closer.
btw, i'm aware of your ppk grow and am heading over there soon. thank you!
