That sounds like a project crying out to be made.

how about a 12W-15w rear light bulb, placed in a box under the container of soil (to warm the soil) 12W would draw 1A from a 12V battery, - thus a 70AH car battery would last for probably 48 hours before needing to be recharged (as its never wise to completely flatten a car battery)

You could trickle charge the battery with a photocell panel.  Im not sure if its a good idea to have a lead acid battery indoors, fumes etc.  So might be best in a shed or greenhouse.
