do u mean that little tiny system aerogarden with the built in light? I saw one in the growshop with basil growing in it and thought what a load of shit lol if it is put a pic up iv never seen one with weed in it. Ive heard trainwreck grows huge calyx's, some of the largest around but tastes foul. If it is that little aerogarden u mite wana start 12/12 as soon as you see roots, or they'l outgrow yr aerogarden in terms of height and rootspace. Clones will root in a hydro media with just ph adjusted water, by adding the nute tablet u could have done more harm than good, burning the delicate root nubs beginning to form. Clones generally root within 2weeks, but can take longer if conditions arent ideal. I use growth technology root riot cubes, they dont need ph adjusting, come pre soaked, organic and proven to root faster than rockwool i typically get my first roots showing in 8-9days. Did u dip the cut in a rooting hormone gel or powder? Not essential but improves cloning success rates. And if yr getting some upwards growth chances are u have some roots already and theyre just not showing thru the media yet...
