I have two female plants(unfertilized by male) growing outdoors and am anxiously waiting to observe signs of flowering. Both are about 4- 5 feet tall
What are the first signs of flowering?
I also heard that it needs 12 hours of sunlight to flower but i grow outside in Florida and cant control the sun. So any suggestions?
If i don’t give it 12 hours will it eventually flower anyway or just keep growing to a giant plant without bud?
After you have pre-flowered your plants to determine their sex, its time to decide if you want to flower females for buds or if you want to flower males for pollen and cross-breeding. Female plants are known for their heavy, potent flowers filled with resin. The best strains for indoor growing are the ones that stay short and bushy with branches close together, creating denser buds and requiring less space to be grown in. Cannabis plants will start to flower when they receive 12 hours of light per day. In order to force flowering you also need to change the nutrients and the lights from metal halide to high-pressure sodium. Most strains will show signs of flowers within 2 weeks of being introduced into flowering. The flowers will appear near the top of the plant, small white pistols will appear as shown in this picture. The flowering time varies from strain to strain, averaging 9 weeks. Once your plants are done flowering you will need to harvest them.
Male Cannabis Plants flower approx. 1-2 weeks before females. When male plants flower they release pollen, which will find its way to a female, creating buds filled with seeds. If you do not want seeds you need to remove the plant as soon as it shows signs of being a male. If you are choosing to cross-breed, you will want to have female plants in the room you are using for flowering marijuana.
