AK-48 and Master Kush. You won't be disappointed.

Both are relatively easy to grow, are known for their high yields and potency, and they finish quickly (50 - 60 days). Concerning height, you simply need to know what you are growing and then time veg growth accordingly. Assuming you have 4' I'm giving 1' for the light. That leaves 3' for everything else. You would not want to veg these much past 8 inches. That said, there are others here with far more experience so once you have settle on the strains you should post a question detailing your grow environment and seeking advice on veg height. Also, consider doing a scrog grow. See: An Overview of Cannabis Training (ScrOG, SoG, FIM, Supercrop, LST, etc.) Check my signature for some tutorials that you may find useful.

Note that I just purchased some nirvana seeds via seedboutique.com. They aggregate from a number of seed suppliers so you are not limited to one. Two thumbs up for seedboutique.

Picking A Strain for Fall 2010 - INDOOR Heyall, I'm just looking around www.nirvana.com right now, trying to select feminized seeds to buy for this upcoming fall/winter indoor. I have a four foot tall space, so I need something short. I also want a plant with average or above average yield, and something with a high THC level. I am also a beginner to Indoor growing so I need somethng with a grow difficulty of easy or moderate. So... feminized, short (indica), indoor, large yeild, dank, and easy to grow! :thumbsup: If you Rating: 5
