Here we are at the first snow the year and my strawberry Window Farm is still going. The three strawberries in my original WF on the left are 9 months old. To the right is a new window farm. The resevoir on this is a recycled cat litter jug and holds about 2 gallons. The peas on the bottom are 32 days old and the bib lettuce in the middle are 26 days old. Nothing is on the top yet.
It’s interesting that during the summer, the gallon resevoir on the strawberries needed to be topped off ever few days. In the course of a week I would use about an extra gallon of water to top it off. Now with the change of season and less light, during the week only a pint is needed to keep it topped off. I have no supplemental lighting yet.
With the new WF I went and bought a Petco 9904 air pump that has the 4 outlets so I can supply air to both units. In the second WF I am using a variation on my original Tee air pump design. The difference in this one is the 5″ of hose that is coming out of the bottom. It is hard to see, but this short extension also has smaller hose shoved in it. You can see the plumbers tape in the hose that is holding it in place. With this restriction, I seem to get better nutrient flow up the hose and less air bubbling back through the bottom. The Petco pump has a variable output and I get plenty of flow with it set to its minimum.
Happy window farming!
