I am on my first grow. I have 3 seedlings in 4 inch pots indoors under 2 x 24w T5 lights.
Here is how they look:
They sprouted 12 days ago.
From my research I was under the impression that the goal was to grow them to about 15cm tall in these pots, and then transplant them outdoors to their final homes in the 25 gallon pots. Hardening off somewhere in between.
So my question: just keep at it? Is it ok to grow them that tall in these pots? Or do I need to transplant to a bigger pot before going out to the 25 gallons? Only 1-2 really small roots are showing at the bottom of two of the 4 inch pots so far.
