1. After seeds have sprouted; growers maintain a 18/6, 20/4 or 24/0 light cycle on the plants. This vegging light cycle lasts for about 4-8 weeks. This allows the plant to reach maturity and develop a good root system.

2. Once the plants are sexually mature...about 12-15 inches tall...the growers switch to a 12/12 light cycle. This is the flowering light cycle. Generally, the plants will show their sex; after about 2 weeks...(male/female)...and flowering female plants require another 8-12 weeks to harvest.

3. White Widows can produce as much bud as any other strain...:thumbsup:
