If you like the idea of growing vegetables or herbs indoors without using much space (or light) then look no further then Aerogarden. This gadget uses about 60W of electricity and you can grow plants even if you don’t have any yard space or much sunlight indoors. It doesn’t use any soil, isntead it uses NASA tested aeroponic technology using nutrient tablets which it claims produces 100% organic plants. It’s currently only available in the US and Canada (runs on 110V 60 hertz AC).

Here’s an idea I came across at Groovygreen, paper you can plant. Once your incredibly romantic message on the paper has been read the card can then be planted, a great way to remember the romance. What seeds you incorporate into the paper is your choice and it sounds like a great (if somewhat late) idea for Valentine’s day. Full instructions can be found here including the paper making instructions.
