I just found the Windowfarms website and I’m intrigued by the possibilities of small scale hydroponics. I have a specific need but I can’t find that in the available windowfarms products. What I need is a unit with just one planter. I need this to be a self contained, standalone unit. By this I mean solar powered. Don’t want to use AC or DC but rather the power from mini solar panel. This would pump liquid during the day to the one small plant in the one small reservoir. I have searched the internet for an off the shelf product like what I describe but cannot find it. I’m posting to the community to see if anyone knows of such a product. Or, how to build my own.
