Because, apparently he plans to grow outdoors, and if you only had an initial 12 hr dark period the plant would be confused the very next day outside. Not enough time to fully tansition to flowering. But a week, you're right, much too long.

So, xtcistheshit, outside right? How long of a flower period are you thinking of? It seems to me that the whole point of harvesting sept - oct is because of the length of day that time of year. It is natural for them to become due then. I am not even sure you can get a good healthy flower cycle in this way. But, I am just a grind it out inside kinda guy.
Razer Reviewed by Razer on . thinking of something i am growing a plant that is almost a foot tall and has very fat and short leaves and i want to harvest it earlier than october or so. so i was thinking in a few weeks i could put it under my house into complete darkness to make it flower earlier and it is kind of damp down there and i was just wondering if this would be ok. thanks for the help Rating: 5
