Optic Foliar REV - Foliar Vitamin and Amino Acid Feed
Best for: Growers already running a foliar programme who want to add a fast-acting boost of aminos, vitamins and micronutrients on top of their base feed.
Our thoughts
Think of REV as a top-up rather than a replacement for your root feed. It's a foliar supplement, so it works fast through the leaf rather than waiting on the roots to catch up - handy if a crop looks like it's stalling and you want a quick nudge rather than a slow fix. No pH adjustment needed, which keeps it simple.
Optic Foliar REV is a foliar-applied nutrient supplement built to deliver micronutrients, organic vitamins and amino acids, plus carbohydrate sugars and B1, directly to the leaf surface. It's designed to support growth rate, plant colour and overall vigour by getting nutrition into the plant faster than a root-only feed can manage. The NPK is very low (roughly 0.5-0.6-0.02), which tells you this isn't a base nutrient - it's a supplement layered on top of whatever base feed you're already running.
REV is designed to be sprayed with the lights on and doesn't need pH correction before use, which cuts out a step most foliar feeds require. Optic Foliar recommends running it alongside Watts and Transport as part of their combined foliar routine, though REV can be used on its own if you just want the amino/vitamin boost without the light-absorption angle that Watts is aimed at.
How it compares
REV sits in the amino acid/vitamin foliar supplement bracket alongside other multi-vitamin sprays rather than base nutrient lines.
- House & Garden's Multi-Vitamin range covers similar ground (vitamins and amino support) but is formulated as a standalone product rather than part of a three-product foliar stack.
- Canna Boost is root-applied rather than foliar, so it works on a different timescale - REV's foliar delivery is aimed at faster visible response.
- REV's selling point over a lot of the competition is that it's explicitly designed to combine cleanly with pesticides and fungicides like Azamax, so you can tank-mix it into an existing spray routine.
If you want a fast, foliar-delivered top-up rather than another bottle for your reservoir, REV fills that specific gap.
Usage guidance
REV is a concentrate, so it needs diluting before spraying.
Dosage
Optic Foliar's guidance for the combined foliar routine is a teaspoon each of Transport, Watts and REV per litre of water - if using REV alone, start conservatively and adjust based on plant response.
When to spray
Apply during vegetative growth and into flower, spraying with the lights on since no dark period is required.
Mixing with other products
REV can be combined with fungicides and pesticides such as Azamax in the same tank, which is useful if you're already running a pest or mildew treatment and want to fold in a nutrient boost at the same time.

Who this is for
- Growers running a foliar spray routine who want to add vitamin and amino support
- Anyone whose crop has stalled and needs a fast-acting top-up rather than waiting on a root feed change
- Growers who want a supplement that tank-mixes easily with existing pest or mildew treatments
- Users already running Optic Foliar's Transport and Watts who want the full three-product stack
Best suited as an add-on to an existing base nutrient programme, not a replacement for one.
Our take
REV isn't trying to be your main feed - it's a targeted top-up for growers who already have a base nutrient sorted and want a quicker way to push vitamins and aminos into the plant. The lights-on application and easy tank-mixing make it simple to slot into a routine you're already running.
One we sell a lot of for new growers who are just starting to experiment with foliar feeding alongside their base nutrients.
