You will not get small plants unless you place the mesh above for SCROG (screen of green). As they wont trigger the flowering any faster than usualy. It is natural cyclus mo matter 12/12... they still have their pre flo and flowering period.(Thats like saying don't bother going 18/6 because they will veg anyways.) What are you talking about....Going strait into 12/12 from day 1, forces flowering very early. been doing it for years. SCROG is just that , a technique. We are talkin about SOG. MAny clones, immeadiately into 12/12. No veg time. Or seeds too. I don't see how a restricting screen gaurentees you higher yeilds. Its a great method , but....it's just a method, nothing crazy going on there. This method couldn't utilize a screen anyways. They tend not to branch out this way, leaving you with just cola sticks. In general, SCROG techique is the one that brings biggest yields.
