>>2. Seed manuals and yourself mention that after true leaves appear, it is time to put them into bigger pots, such as 4" pots. Other than shelf space, is there any reason why seeds should be started in small containers and then transplanted to larger ones? Some of the commercial soiless mixes are specifically designed for germination, and others for growing. While you can usually use either, some growing mixes may contain ingredients that inhibit seed germination. >>3. Is Pro-mix BX used for seed starting or repotting, and what is the brand name and a good national chain to find it? Fafard is also good, as well as Peter's/Grace. Look for a "light and fluffy" mix. Some cheap brands from Kmart/Walmart are often too heavy, don't have any air circulation, and are not always sterilized properly. >>4. Do you think coating the white inside of the shop light with reflective material (tin foil, reflective Mylar?) would increase light output and help seedlings? I have a friend in the local University's electrical & lighting department. She says white actually reflects more than metallics like foil, mylar, or even mirrors. White is the reflection (or lack of absorption) of all wavelengths of light. The metallics do absorb some of the light. The back coating of a mirror absorbs a little light. Alex
