I plan on experimenting with the duration of "lights on" cycle during grow.

In my limited research I've done to date, I've come across this a few times:

There is no scientific proof that the plant benefits from anymore than 18hrs of light during the grow (Veg) cycle...

As mentioned above, I do plan on finding an experimental truth to this very question, "Does the plant benefit from more than 18hrs of light during grow period"...

Even we can be force fed -

Enjoy!
