It was more the fault of me not checking the switch on the powerbox. the new ballasts were plugged into the seperate 2 plugs that are on "sometimes" on constant. I was under the impression that I had put it to "timed" so that all the plugs are on the same schedule. and since my warehouse is bout 20 mins away, I didn't go check the lights at 6am when they shut off until yesterday cos I had to do a spray before lights out. total dum dum dum! I had just put 32 more plants in when I installed the new ballasts, and had been also wondering they hadn't urchined and kept stretching. It was a new strain so I figured they just stretch alot. but no! they just vegged for 7 weeks! hopefully thatll crop them larger as well. they're about 5 foot tall now and I can't wait to see how long they stretch now that they are on the right 12/12. i'll take some pics today and show you folks the flowers with new shoots.
