I know on certain bulbs if you touch it, it won't turn on. I don't know if it's the same, our bodies oil will not allow the bulb to turn on, get some gloves on wipe it down with isopryl alcohol (rubbing alcohol) and screw it back in.
I was on craigslist and found 4 mh 150w (55v) ballasts for 20 ea., so today i went and bought one. I searched the model number (Advance 71A8172-001D) and it turns out it is a HPS ballast. I don't know if the 55v means anything but he's willing to sell the others for $10 each..so i'm definitely...
I found this an interesting find, it was from other forums, i'm guessing this is old news to some of you, but probably news to others.
And it's funny that i'm in the *only* state with no marijuana laws
State By State Laws - NORML
thanks :cry:
I gave them an 18 hour rest from light, so they were in the dark since last night, hoping it would let them recuperate and adjust to the new pots. Lights are back on now, germinated few more seeds as backup in case these go downhill.
