I'm getting a small greenhouse 6x4x7 and will have it partially heated in the winter to keep my tropicals, perennials, and some seedlings.

I'm just starting out and don't wish to spend a lot of something elaborate only to find that I did it wrong or it's not what I need.

I just want a simple light(s) to light this small greenhouse for all the plants in it. I know different plants require diff types of lights and strengths but I'm looking for a light that will be an average good light for everything. It won't be the best for every plant, but something that will do some good for every plant. Does that make sense? Also, I'd rather not use hanging lights.

Thanks so much!
