Nice job getting the mylar, it will make a huge difference in the amount of light that is reaching your plant. Hopefully it didn't cost you much. And also nice job getting the 2700K bulb. Keep in mind that 2700K CFL bulbs seem to be the easiest to find bulbs at home improvement stores like Home Depot or Lowe's. Those stores have the largest selection of light bulbs (at least in my area) - most of them useless to us - but I generally see CFL bulbs in the 2000K range for very cheap - like $3-4 for the more luminous of those bulbs. So, hopefully that didn't cost you very much either.

Looking forward to seeing more pics and updates! I know it's not fun spending the money but isn't it fun upgrading and evolving with your grow? That's what I have enjoyed the most.
