Thanks for the help!

On the cups, rather then trimming would it be okay to transplant them to 1 gallon pots instead? Or are there any negatives to transplanting with a seedling? That said I am going to trim then now

I already possess the MH lamp, got it from a friend who moved for cheap, it's a 175W and I have about max 5 ft clearance from where the tops of the pots would be.

I do not have a way to measure the pH (that I know of), however, I'm going to the hardware store tomorrow to buy some things I need in the house (was planning on getting 1-3gal pots as well) and will pick up a moisture/pH meter (if you'd suggest it). If it matters, I'm watering with distilled water which is more or less 7pH, I don't remember much about the non-fertilized potting soil, except it was the only kind I could find and was considerably cheap something like $1 for 8 qts. I water every couple days, depending on how my toothpick looks =\ .
