^^Pretty much what Dive said.

However, if you have the wrong lighting and if it's a sativa dominant strain, it could take twice as long in some cases.

Can you take some pics of your plants and setup? If we see what's going on, we can guide you a little better :thumbsup:

Until then, you should start reading up on all the FAQ's and the stickies in each section. Here's a few that should get you started:

Grow FAQs - Cannabis Forums Message Boards - Medical Marijuana, Cannabis Club, Dispensary, News
http://boards.cannabis.com/basic-gro...-dankness.html
http://boards.cannabis.com/indoor-gr...-progress.html
http://boards.cannabis.com/indoor-li...-lighting.html
http://boards.cannabis.com/indoor-li...uch-light.html

You can also download the "GrowFAQ" from here (it's like 205 mb or something), which answers just about every question you could ever have. It's a great guide for noobs.

Plenty more than that to go through, but it should get you started. Welcome, good luck, and keep us updated :jointsmile:
