Pest Control

The yellow colour pulls in flying insects: whitefly, fungus gnats, thrips and leafminers land and stick. Traps catch the odd winged aphid too, but aphids cluster on stems rather than fly, making garlic concentrate the better choice.

They work on colour, not bait. Insects head for the bright yellow, then the glue coating both sides of the sheet holds them. The printed grid makes counting easy, letting you track if pest numbers rise or fall.

Sticky traps are highly effective for monitoring and reducing flying pests. They catch adults and give early warning, but they will not clear an infestation alone, since they do not stop insects breeding on the plant. Use them to detect, then act with garlic concentrate or predators.

Replace a trap once it is covered in insects or dust, usually every two to three weeks. Check and count the catch weekly, and swap them sooner in a heavy infestation. A fresh, tacky surface catches far more than a crowded one.

Yes, yellow traps catch adult thrips. But, because thrips do most damage as larvae feeding on the plant, treat traps as a monitoring tool and pair them with garlic concentrate for control.

Hang traps just above the canopy and raise them as the plants grow. One trap per square metre monitors an area well; space them evenly, and lay one flat near the soil to catch fungus gnats emerging from the growing medium.

No. Sticky traps catch flying adults, but some always escape to keep breeding, meaning they monitor and reduce, not eradicate. Combine them with organic garlic concentrate, clean grow-room habits, and early inspection with a microscope.

Yes. Garlic is one of the most effective natural deterrents against spider mites; its organosulphur compounds make plant sap unappealing to them. Rogis OFG Garlic feeds this into the plant's sap flow, causing mites to stop feeding.

Add garlic concentrate to your nutrient water so that the plant carries the deterrent in its sap, then monitor with sticky traps and inspect leaf undersides with a microscope. Rogis OFG Garlic does this without chemicals near your buds, and doubles as a fertiliser.

You can boil crushed garlic in water, strain it, and spray, but a spray only coats the leaves it reaches and washes off. Rogis OFG Garlic skips that: mixed into nutrient water, the plant absorbs it evenly, even in hard-to-reach corners.

The best organic setup combines detection and prevention: yellow sticky traps to monitor flyers, garlic concentrate to deter sap-suckers, and a microscope to catch trouble early. Rogis OFG Garlic also feeds trace elements and NPK while it protects.

Keep the grow area clean, quarantine new plants, and inspect weekly. Add garlic concentrate to nutrient water as a preventive deterrent, and hang sticky traps to flag any flyers early. Prevention costs far less than clearing an established infestation.

Check weekly, turning leaves to inspect the undersides where mites, thrips and whitefly settle. Watch for stippling, yellowing, webbing or sticky residue, and run a pocket microscope over new growth. Sticky traps give a second early-warning line for flying pests.

On indoor plants, add garlic concentrate to the water so the plant deters mites from within, and lift humidity slightly since mites thrive in dry air. Inspect leaf undersides with a microscope and hang sticky traps to monitor. Repeat until the plants stay clear of mites.

For reading trichomes, 30x to 100x is the sweet spot. Our Pocket Microscope 60-120x sits right in that range for judging colour, the Pen Microscope 24-53x suits a quick look, and the 20x scope fits whole-plant pest checks rather than trichomes.

Zoom in on the trichomes, the resin glands on the buds. Harvest when most trichomes have turned from clear to milky-cloudy, with a few turning amber. The pistils darken from white to reddish-brown. A 60-120x microscope shows the colour clearly.

Clear trichomes mean the buds are immature. Cloudy or milky trichomes mean peak potency. Amber means the buds are past peak, tipping toward a heavier, more sedating effect. Most growers harvest when trichomes are mostly cloudy with a few amber.

No, most reach only 30x to 60x and have no light, making fine detail hard to read. An LED pocket microscope with 60x to120x gives sharper, lit magnification for judging trichome colour with confidence.

Hold the scope against a leaf, stem or bud, switch on the LED, and turn the focus wheel until the image sharpens. Check leaf undersides for pests and eggs, or the buds for trichome colour.
