Looks like I'm about a week behind you. Only one baby popped the surface so far.
Im ok with that, as long as they keep showing face. I planted them directly into the one gallon pots, so that should avoid seedling transplant stress.
And I'm a firm believer that the first burst of root growth is one of the most important times in a young plants' life.
Initial root growth is important because they will be supplying the basis of foundation for our girls. Root growth occurs before top growth, and the top growth is in direct correlation with how healthy/large. The root system is.
And being they wil start in the same pots they will finish in, they should do better than a series of up potting.
(other side of the coin)
Not to say that step up up potting is a bad thing. This method, we start in a seed tray/yogurt cup/solo.. What have you...
then as the roots become semi bound, they become denser.(side shoot roots) and we keep stepping up in pot size until pot size reached or plant size says" you need to flower me now"(we all have different needs and situations)
Then you'd have more root mass, which when uppotted becomes more building material for top growth.
I think the step up method works get well. For those that are going to veg longer than I am.
Just saying..
