I wanted to try growing organic herbs on the window, but realized that hydroponic system was too much for me to build and maintain. I did not want to experiment with water filled containers hanging over electrical heater, which is right under my window. Instead, I decided to go for "in-soil" method. I am using various plastic containers from produce, and seltzer bottles as pots.
Materials purchased so far are:
Untreated wood planks and screws for shelves
Jiffy Windowsill greenhouses
Miracle-Gro Organic soil mix
Heirloom and organic seeds from Botanicalinterests.com
$40 for seeds (I have plenty left for future crops)
$50 for shelve materials, soil, and greenhouses.
I am attempting to grow Basil, Chamomile, Chives, Sage, Arugula, Kale, Lettuce, Chili Peppers, Swiss Chard, and Cilantro.
Step 1: Shelve
My window sill is very narrow. I used two 2 1/2" wide and 3/4" thick planks with additional support in the middle. The construction is very simple: each side is nailed to brackets (2 screws to the wall for each).
