Question: Dear Ed,
I am away a lot of the time but I still want to grow a garden. How do I do it?
– Kip Fillet, Amstel Holland
Ed’s Rosenthal: Dear Kip,
I would use a hydroponic wick system. It is easy and inexpensive to set up. Once you get it going it takes care of itself.
Use pots with drainage holes. First, cut enough braided nylon rope (about 3/8 inch (1 cm) thick) to hang down a hole from one end of the container, across the bottom to an hole opposite on either side of the container. The length of the cord is determined by how high the pots are raised over the water/nutrient solution, in a tray below the container. Bricks or a wood block are two solutions to elevating the pots out of the water. Fill the pots with high quality planting mix.
Fill the tray with nutrient/water solution and install a flush valve attached to a reservoir so that this water level is automatically maintained in the tray. Place a CO2 unit regulated by a CO2 meter. Enclose the area in curtains or a room and make sure to provide adequate cooling, you only have to visit once a month. Additionally, the plants are less likely to be infected because you wont be visiting.
