Loved growing with Aptus for the first time. Not sure yet, but although they were'nt as productive and didn't have such trichomes as the greenplanet ones, Aptus gave me some of the best built plants I've ever had, and compared with the others I felt like the timing of each nutrient in each stage is really well calculated, they went through the changes much smoother than the others. And better smells with Aptus as well! (:
