well all i can say is im an hydro grower and ive had cutting at one week old from rooted clone shoot up over 5ft in less than 3weeks, i had to top and supercrop the feckers right up till the last week, that was vanilla kush, never again lol ;-)
lol softy, its easy, do get what your saying as it looks nasty to see your plant bent over like that but a day or two later and she is back looking good
6ft high is not high at all, time you have your pots or trays then the hight needed for the lights, not a lot left for big plants, you will need to top like mad and keep ya canopy low all the time..bit like scrog lol
don't get your self boged down with all the shiz thats about in this site and all over the net, keep it all simple and thats what ionic is and its cheap and all you need, some strains like kush will need ionic boost and bloom but lots do very well on just ionic grow from start to finish(fuck all...
don't ya just love hydro, some little pics of my little hydro grow, full of uk clone only exo, food just ionic what else lol ......................... ;-)
