I'll be using Aptus on two of them and GreenPlanet on the other two to see the diference.
The two on the back are Baked in Paris, and the two in the front are In-Z-Air. The left side is beeing fed with GreenPlanetNutrients, and the right side with AptusPlantTech.
Took some good picture show for you guys to see them, and try my luck at the contests :)
