Ok, so I've been leaving my lights on for about 12 hours every night, and so far my plant seems to be growing. I'd say it's about 2 inches tall, and I think I started growing it about a week ago, though I'm not sure. Tbh, I didn't think it would grow so I didnt pay much attention to the times I left it on. Sometimes I turned the lights on at 7.30pm other times 2am.


Basically my questiosn are these:

at what point in the flowers growth should I change the amount of time under the light?

and how much time shoudl I leave the light on?

and how far away should the tip of the plant be from the light? (I have a pretty standard fair UV light, no fancy growing equiptment).

i think u just change it to 12/12. (12hrs light 12hrs dark). Also type into google "the cannabis grow bible" and download it.
 
I keep mine under a 18/6 untill im ready to make them flower...a good time would be when its about 3ft tall. at that time switch to the 12/12 lighting. and get a couple grow lights from walmart there like 10 bucks a piece and all you do is plug em in. a 24 hour timer is a good investment there cheap to.
