Lighting good 400 hps bulb?????

med grade imo......hortilux has served me well:smokebuds:
 
Hortilux!!! Get what ya pay for!!! I you are gonna go....go with the best!!! Don't skimp on yer bulbs!!! One of the most important aspects of your grow!!
 
If you have magentic ballast for those bulbs check out Ceramic Metal Halide bulbs!!
Perfect for start to finish growing.
Results are amazing.
Nice, bright white light that the plants look normal under.
Great color spectrum and long life!

:peace:
 
Not sure what a magnetic ballest is, mine isn't dimable and is from htg supply, cord doesn't disconnect from light or ballast
 
Gardener, the Lumatek bulb is absolutely fine. Asking what bulb to go with is sorta like asking which hair color on a girl is hotter. Everyone has their own opinions. I have used Hortilux as well as Ushio, both high $$$ bulbs. I will say if you have a digital ballast, I would shy away from Hortilux as they are very well documented to have serious problems with some manufacturers. Lumatek being one of them. Thus the reason I went to Ushio. I run Lumatek digi and Hortilux would not warranty their bulb because of it. It plainly states that on their website, I just failed to read it.

Long story short, the Lumatek bulb you linked to will work perfectly fine for you. Are some bulbs better than others? Of course. Will it make a major difference? Nope.
 
Gavita enhanced al THE way if your using boostable evsa,
else id go for Philips hpi/hti

But the big question wil be what are you Looking for in ur grown weed
For that bigyields go for more red, if your Looking for THE best stone/high and want ur trigs/Terps as best as they can get go for more blue or go for Mh

I remove my hps bulbs after +/- 6 weeks of flower back to Mh for the last few weeks (8week strain)
