Hydroponics - Indoor Horticulture

Hydroponics - Indoor Horticulture represents an educational, in-depth, up-to-date, indoor horticultural growers guide that covers all principles of indoor Hydroponics Indoor Horticulture by Jeffrey Winterborne 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.

This book goes further than any indoor growers guide has gone before, presented in full colour with 3 dimensional CAD renderings. Hydroponics - Indoor Horticulture quite simply outclasses any other book on the subject... In terms of literal content, quantity, quality and presentation, no other indoor horticulture growers guide can compete, let alone compare.

Thrips (Thunderflies)

Thrips are small, slender insects which measure about 2-3 mm long when mature. On adults, two pairs of narrow wings fringed with long hairs are visible and when at rest, the wings are laid along the back. Their colour depends on the species, but these can range from a pale yellow through to a greyish yellow-brown to black. In order to establish characteristics which distinguish the different species, magnification is required. Recently, new species have been introduced from abroad and can be potentially damaging pests, such as Western Flower thrips, Glasshouse Banded thrips and Palm thrips. Thrips like company and usually appear in large numbers on leaves or flowers.

Preferred Host Plants

Many C3 plants, crops and ornamentals can succumb to infestation, most frequently on cucumbers and flowering plants.


Thrips suck sap by puncturing leaves or flower buds with their mouthparts, and the affected parts become blotched or flecked and dry out. In very acute cases, the plants appear to have been burned. When leaves or buds swell, they can become contorted or torn, and form windows in the tissue. The thrips are visible, usually in large numbers, near the veins on the undersides of leaves.

Life Cycle

A female can produce approximately 60 eggs during

the course of a season. Eggs are deposited on the undersides of leaves, protruding from a tiny cut in the plant tissues. The larval stage is about 10-14 days in the case of the common Tobacco thrips, whereupon the larva drops to the ground and tunnels into the growing medium to pupate there. Reaching the adult stage takes another 4-7 days. Thrips are quite vulnerable to insecticides, but can be quite awkward when other biological control agents have been used and this prevents chemical control. Fumigation between crops can be a useful remedy, but pesticide residues can remain for some considerable time and prohibit future use of biological control in the grow room.

Biological Pest Control

Amblyseius Mackenziei and A. Cucumeris Both species of amblyseius are small predatory mites approximately 1 mm in length with slightly flattened bodies which are pear-shaped. They are a pale brown colour. They are very energetic and scatter over a wide area. Their white eggs can sometimes be seen attached to plant hairs.

Life Cycle

Amblyseius have quite a long lifespan, and can produce several eggs a day. Both adults and young mites will eat thrips. They can also eat bugs other than thrips, for example, young spider mites, so they can survive even if the thrips population has been diminished.


Amblyseius are sent out as mobile mites that are mixed with bran. This is sprinkled over infested crops. Now available are small sachets that contain bran and mites which can be hung among the plants where the mites then scatter. These sachets also contain enough food for the amblyseius to survive should food be in short supply, or if they are introduced before the thrip population has multiplied enough. These sachets are sometimes called ‘breeder’ or ‘grower’ packs. Amblyseius are not particularly fond of low humidity, and lengthy, dry and hot spells can cause their numbers to reduce quite significantly. Damping down or misting during these hot periods can be beneficial. These sachets should be placed out of direct light and away from heat sources.
