First time starting seeds under fluorescent lights. I have some seeds (Coreopsis, Gaillardia) that I am told require light to germinate. The seeds will be placed on top of the soil medium (Coco coir, peat, vermiculite) and watered lightly. So, the question is, how close do I put the lights and can I use a humidity dome?
any help is much appreciated
Thank you

How close you place the lights depends upon how strong the lights are. It could be just 2 or 3 inches or a foot or more. Fluorescent lights are limited - all the light goes straight down so the seeds will have to be directly under the lights, not off to the side.

I hope you are planning ahead for planting your seeds 4 - 5 months from now. I am confused by you choice of starting medium. You have chosen three ingredients that, when wet, absorb and hold moisture - you will have muck. Use those ingredients for 1/2 the volume. Make the other half compost and perlite.

Thank You for your response, I didn't realize all of these ingredients absorbed and held water. I'm going to make my own mix and am looking for ideas. One of the commercial mixes sold here contains the ingredients I listed in my first post along with a little lime. I think perlite is the way to go.
As to the lights, they are two 4' shop lights with a mix of warm white and cool white tubes.

Thanks again, Bob
