My fire escape salad bar has two sub-irrigated "serving trays". The one on the left is a City Pickers sub-irrigated planter (SIP) from Home Depot. The small window box is a conventional drain hole planter converted to sub-irrigation. I haven't picked any leaves yet but we're getting there.
Incidentally, because of end-stage osteoarthritis in both knees (to be replaced), I cannot power walk daily as I used to. As a result, my weight slowly climbed up to 220 pounds. I finally realized the strain these extra pounds were putting on my knees, along with the negative aspects regarding my overall health.
As a result of a "calorie reduction" program (as in not eating so much) and eliminating ice cream, chips and pretzel snacking I have lost 40 pounds since last November. I eat only two meals a day, oatmeal and fruit in the a.m. and stir-fry or salad for dinner, no junk food.
My meals never tasted so good. The two meals a day method is probably not what a dietitian would recommend but it is working for me. Now the trick is to avoid gaining it all back. I’m looking forward to salads made from assorted fresh picked fire escape salad greens.
