which of these bulbs are better
Grolux 400w Dual Spectrum
Sunmaster 400w Son T Plus
are they metal halide, high pressure sodium or what?
HPS m8
which is better for 12 hour flowering cycle ?
not really shure but anything HPS will be really good fur ur plants there. make shure ur keeping the heat to a minium about 70-80 degrees F.
Live :stoned: and grow those herbs nice and high
go with hps. using 600w hps plants love it.
we need to know what kelvin each light produces.
I'm using a 400w Grolux hps (58,000 lumens) and I'm really happy with the results. But mine is just a regular Grolux hps - I don't know what their dual spectrum bulb is.
PC :smokin:
the dual spectrums lumens is 58000 but it said that it has a blue spectrum as well i thought plants did better under an red orange spectrum in flowering ?
The blue spectrums are to help during the veg stage, it's added to the HPS red spectrum, no loss of lumens....Quote:

I tried looking up the duel spectrum bulb couldn't find it, could be due to different continets!
Lets try this, I need the manufacture name, if a majoir manufacture there is a model number on the box. (ex. 400/mh/eco)
This will help alot then I can tell you everything about the bulbs.
