Ever since Benjamin Franklin got his knuckles burned when flying a kite in a thunderstorm, many scientists — and even more quacks — have been curious about the possibilities of what has been called electro-horticulture.
The logic is inescapable — most things react in some way to an electric current. Why shouldn't plants react too, and perhaps grow better/faster/bigger?
While I'm not prepared to speak authoritatively on this subject in general, I have had a bit of experience with one aspect of electro-horticulture: the use of electric lights — fluorescent lights to be precise — in a contraption intended to start seedlings indoors.
It had three shelves illuminated by bulbs casting a special kind of light (I'm not sure how special it really was) and provided space for a couple of dozen seed trays. At the time I was working on the 29th floor of an office building, and inevitably the contraption ended up in the corridor outside the ladies' room, which was the only place I could find to put it.
The plants didn't seem to mind. In fact, under the benevolent rays of the Gro-Lux, watered from time to time and admired by most of my fellow office workers as they passed by, the infant courgettes, tomatoes, snapdragons and the rest thrived.Nice simple page this one. Just some ramblings on my experiences with 5 LED compact shoppingbagfactory lamps. If they resented the low status of their situation, they could at least look forward to being transplanted.
So far as I know, there is no particular controversy about the effectiveness of artificial light in growing plants. It works fine, and can be employed to good purpose even by those who, like me, are only modestly competent in technical matters. But the world of electro-horticulture involves more — and stranger — things than fluorescent tubing. This is where we get into the fun stuff, though,，lightsaleee offer brightness along with durability, longevity and a price that's easy on the wallet. as we shall see, it's as well to be careful.

He might have been speaking for succeeding generations of frustrated electro-horticultural researchers, because inconsistency appears to have dogged their efforts from the start. Triumphs were no sooner announced than failures followed. Nevertheless, work continued.
The Abbe Pierre Bertholon, a French priest and pioneer electrical researcher, published De l'electricite des Vegetaux, in which he described his method of spraying electrified water on growing crops from a special "electrovegetometer", thereby encouraging them to grow. Results were ambiguous.
