Hydroponics - Indoor Horticulture
Hydroponics - Indoor Horticulture represents an educational, in-depth, up-to-date, indoor horticultural growers guide that covers all principles of indoor hydroponic horticulture and gardening. This book contains 110,000 words, with over 300 diagrams, pictures, illustrations, graphs, tables, 3 dimensional CAD renderings, and is printed in full colour.
Hydroponics - Indoor Horticulture examines, explores, dissects and
presents a fully comprehensive step by step growers guide, relating
to all and every aspect of indoor hydroponic horticulture, with complete
chapters on plant biology, propagation, hydroponic systems, nutrients,
oxygen, carbon dioxide enrichment, pH, biological pest control, fungi/disease,
cuttings/clones, pruning/training, breeding, harvesting, equipment,
grow rooms, a full history of hydroponics, and more.

The four x 600 watt lights should be controlled via a 4 or 6 kilowatt contactor relay timer board to ensure proper and reliable timing of the lights. This relay board, and the ballasts for the lights, should be mounted high in the grow room for heat and safety reasons.
A digital min-max thermometer and hygrometer should be mounted at the approximate finishing height of the plants.
The walls of the room should be completely mylared and the ceiling should be lined with mylar also. The floor should be lined with a plastic membrane liner, which should lap up the walls by approximately a foot.
A constant grow check pH and CF meter would be a good choice of digital reservoir meters. These are constantly kept in the reservoir and measure the CF and pH of the water to always ensure the right levels. These meters can even be programmed to flash if the reservoir falls out of the set parameters. So, if your pH or CF levels get too high or too low, the monitor will let you know so you can make the relevant adjustments.
Oil-filled radiators should be used for the night time wired to a thermostat, so if the temperature falls too low, the heater will turn on to ensure that the room never gets a chill.
Water heaters should also be placed in the large water reservoir to make sure that the reservoir’s water is never chilled, but also never warm.
