What reading level is Electro Horticulture book?
To quickly assess the difficulty of the text, read a short excerpt:
Recently a gardener, without any scientific abil- ity, and without even the intention of experiment- ing, arrived at a similar conclusion. He was extremely puzzled one day to find that some lettuce plants at one end of his greenhouse were far in advance of those of the same age and variety at the other end. He was finally led to conclude that an arc-electric lamp, which had been burning every night at the prolific end of the lettuce bed, was the cause of his good fortune; and further ex- perime...ntation proved his conclusion to be correct.
The arc-electric lamp furnishes a light very similar to sunlight, being, however, somewhat richer in the rays beyond the violet and slightly 21 22 deficient in the orange rays. The use of an orange- colored globe makes it more nearly like sunlight, and favors its action upon vegetation. The naked arc-light, if too near some plants, exerts a detri- mental action upon them, and one must carefully study the susceptibility of the individual plant in order to regulate the distance between it and the light.
