Successful germination depends on the right amount of warmth, darkness and moisture. You should use clean water that is PH neutral with a small amount of chlorination to kill parasites in the water.
One of the tried and true methods of germination is to fill a glass with your PH neutral water at room temperature, place the seeds in the water and leave them in a dark, warm place. Take a look at your seeds about every 12 hours for up to 48 hours. You will be waiting for them to swell and split, push down any floating seeds that you find during this period.
If you can see the small roots starting in the crack, it is time to stop soaking them. Remove the seeds and place them in small containers with very loose soil about ¼ to ½ inch deep. Make sure that your container has good drainage and the soil should be completely damp, but not over watered, in order to maintain the proper humidity levels.
Cover your containers with plastic and get them under your lights and maintain a temperature of 67-78 degrees at all times, the room should be humid.
Take the plastic covers off when the sprouts have grown above the soil and the first leaves start forming. Then keep your soil damp and start your nutrient program at about ¼ to ½ strength of mix.
The other method of germination is to place your seeds directly into a growing substrate instead of soil. Some seed producers recommend this method over soaking or pre-germination of your seeds.
The best advice is to select a method of germination that carries a low risk of problems and issues in favor of one that provides the highest success rates. Again, do your research and select Marijuana dispensary in California that works the best for you.
