Yeah that is what I thought given the color in the picture. Down the road it will make a good seed starter & veg light. With both switches on it will get you quite a ways into veg.
I see about topping. You are going to try to use a clone as your second plant. That will be tough to do. It takes a couple weeks for the clone to establish roots. Meanwhile the mother keeps growing. If you go with a full manifold on the mother, it will buy you a liitle more time to establish the clone. But you will need to flower the clone fairly early and probably only let it grow one or two colas.
Another way is to grow out a bunch of cuttings. But flip the mother early. You can check out my current grow at Another Clone SOG and TBD That thread is about growing out 11 clones plus 2 I threw in the garden.
