If you are only growing a few plants at a time, you want to be sure that they are all female from the very beginning by purchasing feminized seeds. If you then place all the components in a temperature-controlled cupboard, you will have created a self-perpetuating supply of moisture no need to touch the seeds again until they are ready to be transferred to your final growing medium as a young seedling. However, if you aren t careful, it can destroy much more than just weeds.  Source: <a href=https://weareindy.com/community/MauricioCornelius>https://weareindy.com/community/MauricioCornelius</a>
