They are different...
HPS has more light... and will stretch the plants a bit...
MH will make the nodes tighter and will also produce more leaf matter...
...
In MY OP I would NEVER use MH for veg... but I do use for flowering...
It all depends on what you are doing and your preference in doing it...
..
Hearsay should be treated VERY cautiously...

For what reason?
Everything you do should have a reason that MAKES COMMON SENSE to you...
Just cause so and so said it... doesn't cut it..
IF you are doing single cola lollipops... you deff want to veg with the HPS...
That LITTLE extra stretch is a good thing on single colas...

I'll come back and \read everything again...
But are all the connections SECURELY FASTENED?
Is the bulb screwed ALL THE WAY IN???
It almost sounds like someting has a bad contact... flickering the bulb ff.... and the DO NOT fire up right away...
Read your manual... see what it says about the "fault" light...
..
as for your flood times...
Experiment...
I have done up to 12 floods a day.. but I stopped cause it was causing algae to grow on the tray that never dried completely...
Your plants will let you know if you're fucking up...

yes i have read everything over and over again. its screwed in tight. all connections are good. it takes 2 minutes to warm up. the green light flashes when it is warming up, then turns solid green when its up to temp.
the hps is in now so we'll see what happens

so far so good... i added back a gallon of full strength nutes today, there are a little over 10 gallons in the res now.

hey guys sorry i haven't updated in a while. they are doing great! i can't believe how fast they are growing.
my PH and PPM have been almost perfect. i just added a gallon of PH'ed water because the PPM was creeping up around 1400 (using the .7 scale)
in the last few pics you can kind of see how the leaves are kind of yellow. is this from the light being too close?? it can't be nute burn because my PPMs and PH have been absolutely perfect.
regardless of the yellowing they are growing very very fast.
also my F ing digital timer for the pump has been somehow resetting itself at random times screwing up my watering cycle. i'm really pissed. i have two of these timers and they are both broken.
