One of Jack Herer and one OG Kush didn't make it in the soil, although they germinated, so I germinated and planted two more Jack Herers and one White Gorilla haze as an replacement.
So far so good :D
@Swoky, hi, I don´t know. I haven't been using anything else. I'm watering them every 3-4 days. Last grow when she was blooming it was every 2 days. It really helps to air the soil, so it doesn't get too dense. Good luck for you too
