Description
Plant-Extract Pest Protection You Can Spray With the Lights On
Optic Foliar EVIOS is a foliar IPM spray built on plant extracts – lemongrass, clove and cinnamon oils and geraniol – and it pairs with Optic Foliar's REV foliar nutrition to keep plants vigorous across the whole cycle. Optic Foliar describe it as their late-stage flower safe solution. REV supplies nutrients, amino acids, vitamins and carbohydrates for rapid growth, while EVIOS is a plant-based, non-oil-based spray that guards against common soft-bodied pests without oily residue or strong odour. Used with Optic Foliar Transport, both are pulled rapidly into the leaf, so you can spray even with the lights on.

- Works everywhere, suitable for hydroponics, coco and soil
Slow foliar uptake and pest pressure without the oily residue?
Fast-growing plants often need extra foliar nutrition to keep pace, while pest pressure quietly saps vigour, uptake and yield. REV tops up growth with readily available nutrients, and EVIOS knocks back pests naturally with no oily residue, which makes it usable late in flower when many conventional sprays are off-limits.
How to Use
- Fill a clean sprayer with 1 litre of distilled or clean water.
- Add 7.5ml of Optic Foliar Transport.
- Add 10ml of EVIOS. If you also run Optic Foliar REV, add it to the same mix at 7.5ml, the rate Optic Foliar give for REV in their mixing directions.
- Mix thoroughly and do not adjust the pH of the spray solution.
- Mist a fine layer over the tops of the leaves; there is no need to spray the undersides.
- REV: apply every other day through veg, continuing to around week 6 of flowering.
- EVIOS: apply once weekly or as required for protection.
- Turn off circulation fans while spraying and let foliage dry naturally.
- A mix that includes other Optic Foliar products should be used straight away.

Frequently Asked Questions
Do I need Optic Foliar Transport with EVIOS?
Yes. The maker's directions pair every litre of spray with 7.5 ml of Transport. Transport is the spreader that carries EVIOS into the leaf, and it is what lets you spray with the lights on without covering the undersides.
Can EVIOS be used late in flowering?
Optic Foliar describe EVIOS as their late-stage flower safe solution, and it leaves no oily film or strong smell on the plant, which is why growers reach for it when other sprays are no longer an option.
Can I mix EVIOS with other Optic Foliar sprays?
Yes. The label recommends using it with Overgrow, or with Watts and REV, for increased performance. Once other Optic Foliar products are in the sprayer, use the mix straight away rather than storing it.
Will it leave marks or a smell in the grow room?
It is a non-oil-based, residue-free formula with a low odour, so it does not leave the greasy finish or the lingering smell of oil-based or sulphur sprays.
