Click on the photo and it will take you to Flickr. Click on "All Sizes" on the menu above the photo. Select "Original" (the largest view). Scan the photo carefully and you will see many peppers on these plants.
These are not heirloom seeded plants or anything special. They are simply a collection of cell-pack pepper plants from a local nursery. I could have done a better job of identifying them but didn't. My interest was in the growing of them as a test of various homemade sub-irrigated planters. It will be a surprise to see (and taste) the results.
The peppers are not easy to see because they are currently all green and blend in with the leaves. I am going to let them all grow to full maturity and turn color for visibility. Stay tuned.
Note the healthy condition of these plants with no chlorosis of the type you will see in the following photos. Note also that this is a flash photo with resultant yellow light reflection. The peppers are very hard to see without flash.
Compare the fire escape photo to photos here, here, here and here. of plants getting in the range of twice as much sun at Public Farm 1. The east facing pepper plants on the fire escape are shaded by the building in the afternoon.
There are more peppers in the 3' x 3' fire escape area than all the pepper planters I inspected and photographed. Were they just harvested? Judging by the condition of the plants, I do not think so.
What is there to learn from all this? The plants in Public Farm 1 are watered by drip irrigation. They are planted in so-called "smart pots", grow in much publicized GaiaSoil and cared for by volunteers from the Horticultural Society of New York.
What would the results have been if the Public Farm 1 plants were sub-irrigated in a commercially available potting mix (ex. Fafard, Pro-Mix)? The drip system could have been modified with emitters to drip into sub-irrigation reservoir fill-pipes.
An installation of this type would certainly have been more pertinent to the citizens of New York living in close quarters with access to turned earth at a premium. It's too late now but there certainly is an opportunity to learn for the future. Are there minds open to do that? Time will tell.
