This is the surviving white widow a few days ago.
And here is the other, mixed breed plant which is now 2 inches tall, a few days ago.
This is the bubbler setup I'm experimenting with for now:
It's got an air stone and small air pump, bubbling onto a rockwool cube which is resting on a platform above the water.
The White widow is on this one currently.
Here's a pic of that white widow
Looking pretty good for ten days old since germination
Here's the closet setup, you can see the fans along the borders.

Room setup, small fan blowing air in.
