I always just worked along the premise of what you see above ground, you will find underground.Generally when the foliage extends to or just beyond the lip of the pot it will have a good root mass to transplant.
I think that's generally a safe statement. But the first couple weeks after germinating there's a lot more developing underground than above IMO.I always just worked along the premise of what you see above ground, you will find underground.
I'm not sure what i think on this one. I frequently took a youngun grown in soil, to move to hydro, and upon very carefully washing off the roots in the bath, the above ground growth always hugely surpassed what i found in the soil. Who knows. It would often be a 6 inch plant with a 2 inch root ball. Yet at the same time, i've had a 4 inch plant in a pot twice the size of a solo and found roots at the drainage holes. so yeah, i really don't know where i stand on that statment. Am i allowed to argue both sides?I think that's generally a safe statement. But the first couple weeks after germinating there's a lot more developing underground than above IMO.
