Spray with the Lights On, No Residuals, No Leaf Burn
Optic Foliar Overgrow is a ready-to-use foliar spray that corrects nutrient deficiencies and defends the canopy at the same time. It carries the full spectrum of micronutrients, NPK, vitamins, amino acids and sugars straight into the leaf to drive growth and improve photosynthesis, and unlike most foliars it can be applied in full sunlight or with the lights on without scorching.
Key Benefits
- Applied lights-on – no need to shut the room down or work around a dark period
- No residuals and no leaf burn, so there is nothing left sitting on the leaf surface
- Fights pests, moulds and deficiencies in a single all-in-one application
- No pH adjustment required – it goes straight into the sprayer as supplied
- Raises nutrient content within the leaf rather than relying on the root zone alone
- Reduces stress and increases vigour through veg and bloom
Deficiencies That Appear Faster Than the Roots Can Fix Them
When a deficiency shows in the canopy, root feeding takes days to correct it – days of slow growth and poor nutrient uptake you never get back. Pests and mould move faster still. Foliar delivery bypasses the lag by feeding the leaf directly, which is why Overgrow doubles as a fast corrective and a routine preventative through the cycle.
