wow look at those stretch. I honestly havnt seen such young plants that high ever, though I havnt not been growing very long.

Honestly with 1 pot you could do very well by going to walmart and get 2 42w bulbs, 150w equivilent.. i think they are 8.90 each.

They also have reflectors there you could pick up for like $7 each. both those lights shining on that one pot, you could grow some ok week. Just make sure to flower earlier than if you had some better lighting.

Welcome to a great hobby

EDIT: this is assuming you use a bigger pot so it doesnt get root bound.
