Finnally I've listen to your advices...I'm now growing only 3 plants, they are only 2 weeks old, but everything looks nice. After I re-think my setup I'm sure that 8 plants was a bit ambicious. Let's start with some moderation and a better chance of succes

I have a question about mother plant...I know a mother plant should always be kept under the light on a 18 hours light and 6 hours darkness ratio. But how can I make sure the plant I choose to be my mother plan is a female ? What I understand is that we can diffirenciate the sex of the plant about 2 weeks in flowering stage...I'm confused :wtf:

Thanks
