unless you have a specific reason to NEED to trim the top, why not just grow your first plant out, learning as you go ? ... your first grows are likely to give you fits (you may kill it with ignorance and over-love ) .. if that doesn't make sense, you will understand soon enough ... if you just 'let it grow' normally, it will be a lot easier to diagnose problems ... postpone the optional techniques until you grow successfully ... and, don't get discouraged :thumbsup: ... just leave it the hell alone, try to let nature care for it (she has done real well for thousands of years, without our help) ... use the K.I.S.S. method for best results: (Keep It Simple, Stupid) :jointsmile:
