No problem. I know it's a radical idea and a lot of people will stick to what works for them. That's fine.

Whether or not my early regimen results in more females, of course I'm not positive. However, first hand experience has shown me that it does not hinder growth in any way. On the contrary, I have observed less problems in general and an overall healthier plant.

The purpose is to mimic nature as close as possible. In every part of the world where cannabis has evolved, the seedlings in nature receive close to 12/12 hours of light in early spring. Also, most of the time rain is not tepid, even in the tropics. So, why would these factors harm a plant?

Not arguing, just stating my observations.
