i'm pretty sure roots grown down first. feeder roots come second and grow laterally.
Nice bro but what is your base soil in your Super Soil. Do you use Ocean Forest as your base soil that is amended with what Sub suggest? How long did you let it cook? Did you add myco's? I have some great white shark, think i'll be adding it to the bountea or just straight to the soil mix.
i think mad is looking at it from the view that if the stronger mix is at the top, watering will allow nutes to leach down and feed...
if anything both methods lead to optimization by evening out the mix in the pots and then cutting the ss with more base if its too hot.
Also something that deliver's a nice fade at the end of bloom ... Looking for something fully organic or as organic as possible
His theory is your roots will grow into the soil as it needs the ferts. That is why on the bottom and not the top.
