Hi Sal, I'm using a pretty standard 15-minute increment timer, I've attached a picture for you. I don't know what the accuracy is, but I'd guess 3 minutes or so, if I set it carefully.

I had to cut my plant. I'm moving and it simply wasn't transportable. I hope my short grow was informative to others, I learned from it. :thumbsup:

I'm excited about the coming few months!
