I love having fresh basil on hand
Growing fresh basil is rewarding and pretty easy. What other herbs do you grow in your garden?
I have some rosemary and thyme and cilantro. They have their own light, that is purple
That sounds like a UV grow light that they use in greenhouses. Do you have an LED one? They are super efficient and can save you money on your electric bill!
Yes it has a bunch of small LED's and it's on a timer so I don't have to remember 
Do you have favorite dishes that you make with your herb garden? With having rosemary thyme and cilantro on-hand I bet you make some tasty meals!
I like to use the basil on pizza with tomato and garlic, and I add it to grilled sandiwches. I use the cilantro in chicken tortilla soup
Those are some good sounding dishes. Thyme can be added to soups too, especially split pea soup towards the end of cooking add some thyme. Some people even use Thyme leaves in salads to spice things up some.
Yes it tastes great with some oil and vinegar tossed with greens
Have you ever tried growing Mint? That is another good herb garden addition. It tastes good in fresh drinks and iced-tea.
