The winter seemed extremely long here in Iowa (Zone 5), so I decided to start some seeds just for kicks. I planted most of the basics: Thyme, Dill, Oregano, Marjoram, 4 types of Basil, Chives, Cilantro, Sage, Parsley, and Tarragon. All of the plants have done well and I have harvested not only Basil but also Thyme, Parsley and Oregano so far.

The key (I think) is I reflect as much light on the plants as possible by using aluminum cookie sheets and the mylar blanket. This also keeps the plants warm which most herbs need to grow. The lights are shoplights with 2 T8 bulbs (1 warm/1cool)-no need for special plant lights!

I keep the cookie sheets up to reflect the light. I only remove them when I water (bottom water only). I also run a fan-I place it on the left side and run it to keep air circulating.

Basil after it's trim. Still plenty of large leaves left if I need them. Notice the sand on the surface of the pots? I do that to help prevent damping off and fungus gnats.
