Ok guys lets talk real business Im leaning towards the Vero 18s I've read that the Vero 18s are only a little bit less efficient than say the top bin crees Cxa or the Vero 29 so what does that really mean. Im trying to pull a pound out of a four by four tent per cycle or better can a Diy light running Vero 18 as the main show with maybe some reds thrown in do that or do I need a more efficient cob. Any help is appreciated but Im looking for answers with explainations if at all possible. Thanks
