Thrip Control

Thrip control for silvered leaves and stunted growth

Thrips rasp at the leaf surface rather than piercing it, leaving a silvery, papery patch that spreads fast once numbers build — and unlike mites, adult thrips fly, so a light infestation can jump plant to plant across a tent in days. Guard'n'Aid for Thrips (£21.95) is a targeted contact spray for exactly this pest, while Yellow Sticky Insect Traps (£5.95 for 6) catch flying adults before they lay the next generation of larvae in your medium.

Maven Skram Pest Prevention (from £19.95) and Pyrethrum 5EC (£44.95) both work as broader sprays if thrips are one of several pests showing up, and BioGreen Garlic (from £24.95) is a milder, more frequent-use option for growers wanting to deter rather than knock down hard.

Buying advice

Hang sticky traps at canopy height rather than the tent floor — thrips fly toward light, so traps positioned low catch far fewer than ones level with the top of the plants.
