Growerssupply.com has all the parts individually and a GREAT catalog too, from greenhouses to trays, lights, inserts, domes.....etc..give 'em a look. I've ordered a large box of 2 1/2" pots (think it had about 1200). Sometimes you can even find supplies from local wholesalers...(just depends some has a min. order)

Lowes and Home Depot both have vermiculite and peralite in bags (2 qt.) and H. D. has the large bushel bags of either. Some of the larger nurseries in your area might also have seed growing supplies. Call and ask before driving all over the place...lol.

Also betNC, did I get the jist of your question.....how many flats for a 48" light? See pix below. I would think you could do 5 trays under a 48" light. My set up here is 5ft long and about 33-34" wide, per shelf. I can get a total of 7 11"x22" trays on a shelf, and if you can find them ----half trays, they are square and can hold 18 2 1/2" pots. I use to use 6 pack trays but found I could seed more into my pots...see pix 4. Also in pix 3, it shows a foil on the wall.....bought at wallmart, I think they call it a body blanket (sporting goods for about $3.00). I mix my own potting soil from peat and peralite, with a bit of vermiculite as a seed cover. I must grow thousands of seedlings each winter... If you need germination times just ask....... Pix 5 is a sample page from my records.
