Hi, I am just a few days from harvest in my aerogarden. The two girls are about 2' tall the smaller one is a little more then 1'. I started mine in the aero put them in the grow tubes. I used their nutes but I also added some Foxfarm and molasses but only in drops and pinches. I also added an airstone and personally think they are a must. I also kept my eye on the water level and kept it topped. These are autoflowering strains which I think are the only strains that would do well in these because of their size.
