A calendar and cultivator's guide in one from 1979 by Kayo.
Each month is presented with a glorious photo and with cultivation information:
Seed selection, Soil, Nutrients, Germination, Seedling Care, Garden Logistics, Water & Fertilizer, Sexing, Flowering, Pruning, Florescence. Harvesting, Commerce, Consumption
"This presentation is predicated on a growing season of approximately ten months. Those who cultivate sinsemilla in the higher latitudes have found it necessary to make compensations for the short growing season. By using acclimated seeds, greenhouses, grow-lights and, above all, "Yankee Ingenuity," they have created adequate seasons in even the most peculiar locations."
