Update on the hydroponics.
We had our first salad last night with boat-grown spinach and lettuce from my son''s hydroponic science project. It was great! The spring has been cool here, so everything except the tomatoes is growing fast. Unfortunately, the lack of sun has made solar powering of the pump impractical. We''ve used shore power instead, but the pump only uses less than 20 amp/hrs a day, so it''s do-able under decent sun conditions (it only has to be run during the day, but we found the plants grow better if run 24 hrs). Using the wind gen (now winterized) also would easily have worked.
The tomatoes are blooming, but it seems the leafy greens are going to be the producers for now.
As a control, he used a standard potting soil for one bucket and it has actually grown faster - he thinks due to the trace minerals in the soil. The hydroponic mix should be more consistent, though ans certainly easier to bring along.
The set up is too unweildy to sail with, but it could be modified to work except during a real blow. Still, for anchoring or coastal cruising, I think it would work.
Is hydroponics organic? No pesticides are used (great boat advantage), but the nutrient solution is a chemical mix. I say it''s not, but my son says it is because the mix is organic chemicals. Hmmm.
