hey md i just had another quick look through scottys thread and i noticed something kind of crucial for future reference which is really going to help me too.
ok here it is. people always so when a plant stretches it gets between 1.5 - 2.5 x its size. so stretch is relative to size. if your plant is 20" and it stretches 2 x its size it will be 60" by the end but if it was only 10" when u flip it it will end up being 30" make sense.
well scotty only veg'd for 25 days so his plant was small meaning less stretch to fill his screen but if you have veg'd for longer and your plant is bigger you will have much more growth to deal with. i hope that makes sense, it does to me but i wont know for sure till my next grow when i put my new theory to the test.
