I don't know how to describe this, but it's not difficult, at least for me. I give the plants peace and that means a lot to them. Mixing fertilizer is the only thing I struggle with, because Advanced nutriense work better with few components in right time and they work like magic!
ChemPie is 8. strain from Ripper seeds, that I grow and Brain cake is similar,but have diffences. Every strain is great,just depends of growers taste for genetics.
