RE: 'Sunshine' fluorescent bulbs (Follow-Up #3)

Plants use light colors for different things. The green range is mostly rejected--that's why plants are green. (Most "grow lights" have a lot of green; that's why they make plants look so good.) The red, or warm, range is used for setting seed and fruit production. The blue range is used for plant growth.

So, if you're just starting seeds, go for the regular old bulbs. I've used warm white bulbs and cool white, and have seen no improvement in seedling growth with the warm white bulbs. It's the cool white light you need, and your seedlings will thank you for it. If you want to put more money into making your seedling growth better, try to find reflectors for your fixtures, or put aluminum foil or mylar up around your setup.

RE: Standard shop light bulb (Follow-Up #1)

You can get pretty good results from standard shoplights (I'd look for T8s and consider two fixtures side by side), the keys for tomatoes being relatively cool conditions once seedlings are up (no more than about 70F during the day with a drop to 55-60 at night if possible, and keeping plants to within no more than a couple inches from the tubes. The other biggie is not starting seeds too early (no more than 6 weeks before plants are to be set out). A lot of people start seeds way too soon and get spindly plants.

RE: instructions for using PotMaker( wood thing & newspaper) (Follow-Up #1)

Sure it is really easy. Cut strips from your newspaper about 3/4 inch wider than the spool. Let the extra hang over the end and fold into the center. Push cap onto spool and with pressure applied turn the cap a few times. Be sure your news paper is at least 3 thicknesses on the spool or it won't be strong enough. The paper pots will need to support each other so must fill the flat. It is satisfying to find something to do with the newspaper that gives it some value. Al
