HYDROPONICS
Sir,-Little has been heard lately about hydroponics. Was it a nine days’ wonder? MHas the cult or craze died a natural death, or have the enthusiasts gone before? If there are any left in New Zealand, please lead me to them. After nearly twelve months’ inquiry and experiment, I am coming to the conclusion that what is known, at least in this country, is quite harmless. I made an experiment in a small way that included eight varieties of vegetables, but my difficulty was to maintain the vitality in the plant after a minimum of beans, peas, tomatoes or marrows were produced. A few details might illustrate my point. Tomato plants about 4in. high, although they didn’t droop, were very slow, and in five weeks had only added at most 2in.; in the same position, a warm, sheltered corner, the same seedlings in soil beat them out of sight. Not one of ten plants produced more than two clusters, and I had no need to remove laterals as there were none. The fruit ripened in due course and was of good flavour. Runner beans were the same; they kept pace with soil growth and produced a good crop. They were sown on November 18 and by January 9, two beans were picked; on January 30 they were at their maximum. By February 9 ‘they were finished and showed no sign of bloomicrg any more. In the soil they went on until well into April. A marrow plant in coarse sand produced one marrow and could not be persuaded to try again. Cabbages were a complete failure after eight weeks’ trial. With lettuces, out of 12 seedlings only two hearted in eight weeks; all others went to seed. In soil the same seedlings did very well. Cucumbers would not grow for me. Lettuce, radish, carrot and onion, sown on December 16, showed no sign by January 1 (in soil they were all well up), never did any good, and I gave them up. Peas sown on January 1 gave quite a good crop by March 30, and a second picking a week later. On the other hand, they were no good at all in soil at the same date. I am trying hydroponics out just now inside a small glasshouse. Radish seed sown on June 1 is well up on the 10th. If by any chance this letter appears in your paper, I should be glad to get any tips from any reader who may have had better luck.
