Chers jardiniers, J'ai découvert votre projet dans une émission de TV en France (sur La 5, "Les citadins du futur"). Aussitôt, je me suis empressé de
chercher sur le web, plus d'informations à votre sujet.
Je vous félicite pour ce projet et tout ce qui s'imbrique autour.

To many, the idea of organic hydroponics seems like an impossible contradiction. Hydroponics, the growing of plants in a medium other than soil, usually utilizes a chemically derived nutrient solution. Organic gardeners, as a rule, do no like hydroponics: for those who love the soil, the prospect of plunging elbow-deep into a gritty mix of parlite and vermiculite is not very inspiring. Nor is brewing up a batch of Hy-pon-ex or Miracle-gro. How-ever, as an enterprising group of urban gardeners in Montreal has discovered hydroponic food production need not rely upon a chemical nutrient solution ... and, under the unique conditions of rooftop farming in the city, soilless vegetable cultivation has distinct advantages.

Hello

Thanks for the guided tour to the rooftop garden demonstration site. I’m glad I finally got to see what I have been hearing about: quite impressive!

I looked up the problem you had pointed out on some of the lettuce plants, chlorosis on the margins of the lower leaves. I’m not 100% sure but it might be a mild potassium deficiency; if the symptoms progress and show distinct necrotic areas (dried-up brown or tan areas) on the lower leaves then it would be definitely a potassium deficiency. Mind you, this could occur not because there is necessarily a lack of potassium in the fertilizer but because there is an excess of certain other minerals, especially cations like ammonium, sodium, etc.
