At this point, I would say swap the bulb over to the HPS bulb if you have one, and just grow them as long as you can. You will probably get something out of your work. Might not be the best thing in the world, but hey...something is better than nothing! Plus, like you said...it was a great learning experience because every time you make a mistake, you are learning what not to do next time. Best of luck with it either way!
