im using a 400w converter ballast to switch between MH & HPS bulbs....i have the ballast plugged into a free timer i got from HTG Supply.com....
the thing that i'm worried about is that on a few occasions, when it was time for the light to automatically turn back on, it would either turn on a little later than when i set the timer, or have trouble turning on at all...like it makes a buzzing noise and looks like theres electrical current inside the bulb but jus wont turn on..
has anyone else encountered this? also, how serious is this occurence during flowering or vegging? will the plant die if it happens a few times?
