It has been three weeks since we planted the kale, lettuce, peas and radishes on the rooftop and we have seen some good progress so far and some interesting things as well.
All of the crops have sprouted to some degree.
Our lettuce (C.V darkness) was the slowest to germinate. Around the two week mark there were tiny red leaflets showing and since then progress has been minimal. A few of the pots are definitely growing but many of the lettuces are still very small seedlings.
The radish (C.V altaglobe) has certainly flourished. The bright green stalks are a few inches high already and most of the seeds in each pot seem to have germinated (around 5-12 per pot).
Both the kale (C.V red russian) and the peas (C.V little marvel) are growing well. However, something has been eating most of our peas! We think it could be the crows that often hang around the roof top. The peas on the south end of the roof received the most damage; there are still a number of healthy looking peas that escaped being eaten... so far!
We thinned the plants on Sunday to densities more suitable to the size of the pot. We thinned the radishes to three per pot, the kale and the pea to two per pot each, and for now we left the lettuce as is.
Now we wait!
Each week we will document our observations of growth to check for observable treatment effects
