In case you’re having trouble reading the caption, it says: “Fig. 26. Choice Potatoes produced by hydroponics. From 60 to 70 percent of the seedbed was covered with tubers. The yield for 1/100 acre was 1482 pounds.” (Emphasis added.)
Gericke planted potatoes at the rate of one plant per 100 square inches in 6 ft. by 10 ft. beds containing about 4 inches of litter made from wood shavings, wheat straw, and sawdust, which was kept moist with fertilizer solution.
An amazing variety of crops can be grown using hydroponics, and the results can be impressive, as you can see. With simple hydroponics practices plants get all the nutrition they need and use less water. Hydroponics could be a life saver during drought conditions.
The wonderful news for you is that hydroponics doesn’t have to be difficult or complicated. You can grow garden vegetables at home with hydroponics. Begin with some lettuce or your other favorite salad greens.
