By far and away, your best bet it high intensity T-5 tubes rated at 6,500 k.
I am using these tubes to grow orchids. See images.
In this first image you will see part of a three tube shelf. This was taken in early March. By know I have additional orchids and some random succulents which are loving these lights. They are on 15 hours a day from 7 am until 10pm, twelve during the winter.
This second image shows a cart with two tubes per fixture. The succulents like that just as much.
I have 18 tubes running on three carts. Electricity is about .80 cents a day.
A site like Gardeners Supply in Vermont has all types of lights, fixtures and carts. Just google Gardeners Supply.
I am 100% positive that this is what you need. You can keep them under them all the time. This would not be supplemental light. Moving plants from here to there is not really a good plan. You could tip pots over, drop them etc.
hopefully this gives you some ideas.
