A few questions

[Volker]

I was wondering if a marijuana plant can be grown inside of a container from start to finish - if it is provided proper circulation, lighting, and nourishment.

Sure. Why not?

Also, a very newb question, how long does it takes for a MJ plant to grow. The strain I am looking into is White Widow...how tall does this strain get (From what i read no taller than 2.5 ft) but also how wide it gets and how long it takes to grow and flower.

Anywhere from 3 to 8 months start to finish, depending on strain & conditions.

White Widow is an "average" sized indica dom, I guess, getting anywhere from 2.5 to 5 feet tall.

Also, how much does growing a MJ plant rasie your electric bill by? Assuming that you are using good lighting, but just for 1 plant.

1. Find you power consumption in Watts. Divide by 1000.
2. Find your price per kW/hr.
3. Multiply for cost per hour.

I.e. 600W HPS @ $0.17 kW/Hr
600/1000 * 0.17
0.6 * 0.17
0.102 or a little over 10 cents an hour. Call it $2.50 a day.

Also, how much bud can you get off of 1 white widow plant?

Depends on how ya care for it. Anywhere from nothing worth mentioning to 5 oz.
