Here is a simple video on how I like to germinate my cannabis seeds. There are many ways to do this, I thought I would share my methodology with you all. Also GrowerMD made a video today as well showing how he germinates seeds. It too is a great way to “pop your beans” Please also watch his video to learn other ways to this also.
Regarding “green” on top of large rockwoool; that is caused by touching the rockwool. It doesn’t seem to affect the plant but it’s a good idea to limit the amount of handling of the rockwool cubes.
