this is the thread i've been looking for! great discussion on the Sun System 150W HPS
I've been debating purchasing it. I'm also a CFL grower, just Veg'd under 125W (blue spec) CFL and flowering currently under a 125W (red spec)
I'm not happy with the penetrating power of it, top buds look awesome and the next node below it looks well also. But the lower shoots are just hairs. Even though it's not a MUCH higher wattage, its still 2-3 times the lumens and will definitely have better penetration power.
After hearing what was said here about the temps compared to CFL I am SOLD!
thanks everyone ordering mine today!
