Hi people I'm just about to top my plants and then use them for clones .. my plants are about 12' high with plenty of nodes but I've read that I need to leave them for 4 weeks after topping them before I can flip them... is this true. If it is I've totally underestimated how long it would take as I was gonna flip them in the next week or so.. thanks for any advice given and will look forward to what peoples thoughts are on this
