This is my first indoor grow...

The space Im using is around 3x3 but still working on the perfect setup
Got some Veg, Bloom & Fish nutrients
Haze seeds, One random seed and 2 G13xJack herer...
Growing medium is African violet mix with a few micro nutrients waiting to be added. (Bat Guano and so on...)
