new grow room 250w or 400w hps?

i have always heard that MH is for veg and HPS is better for flowering.

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...

here are some more pics with the metal halide. they are growing fast!

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'm trying to get nugs as soon as i can. but i will prob put it back in tomorrow or the next day. tomorrow i'm doing my first res change and i'm using the lucas formula. 0-8-16 so no grow 8 micro and 16 bloom. per gallon

well instead of flooding 4 times a day at 12am, 6am, 12pm, and 6pm. i am now flooding 8 times a day. at 12am, 3am, 6am, 9am, 12pm, 3pm, 6pm, and 9pm

i changed it because it seems like they are getting just way to dry

gypsy did you see that post ^^^

ok so something weird just happened. the light went out and the ballast show the fault setting. it says to unplug for 5 minutes then plug it back in.....i'm waiting with it unplugged. i hope its the bulb not my new ballast...

well its working now, we'll see what happens...

it just happened again. i hope its just the old metal halide bulb. i unplugged and waited 5 then it fired right back up. if it does it one more time i'm putting the hps back in...

and it just happened again.


i'm putting the hps back in now.


i'm praying it solves the problem

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...

i put the hps back in. i also put a fan on the ballast to keep the heatsink cooler. its seems to be alot cooler now

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

Good Luck...

some more pics, they seem to be growing even faster with the lucas formula

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.

btw i only have like 105 volts at the outlet the ballast is plugged into

i am so fucking sick of resin hitting my bowl

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.
