Starting seeds early is addictive... so much so, this year I upgraded and put together a pair of grow shelves. 100 bucks for the shelves, 10 per light fixture, and 40 for a 10 pack of T8 grow lights. Wide spectrum or cool white seems to be just right to get most plants off to a good start. I like to put a fan on them for an hour a day when they are on their second set of true leaves to strengthen their stems. Not too bad compared to commercial stuff and works just fine!
Since I'm cheap, I just use plastic cups and potting soil. Plop in two seeds per cup and use cardboard boxes from costco for trays.
I saran the tops of the boxes till I see the first sprouts, place under grow lamps on a 16 hr timer operated lighting cycle and use a spray bottle to water till the first set of true leaves emerge from all cells. Divide up doubles and grow anywhere from 4-12 weeks or so inside prior to driving them home to washington to plant.
This is what the condo's balcony looked like last summer. Everything was started on the grow lamps and was a tiny piece of what I had at home.
This is the spring forget-me-nots and pansies that are going up this weekend for some early color. They are still a few weeks from setting up flowers though since I didn't start chilling them till last week, and they need about 4-6 weeks of cool.
Good luck with the indoor seed starting! It will suck you in and before you know it, you'll be in a jungle!
