The hydroponic grower is always having to be on the look-out for pests that could decimate the garden. The phrase "an ounce of prevention is worth a pound of cure" could never be truer than when talking about garden pests. A silicon additive in your feeding regime will strengthen plant cells making them more resistant to attacks. Neem oil is a fantastic deterrent to most garden pests, including spider mites. If you still get an infestation despite using silicon & neem oil then treatment with a powerful product such as pyrethrum 5EC will almost always do the trick!
