Plant Mechanics LED Fuel (Frost + Aroma 250ml / 1L / 5L)

What is Plant Mechanics LED Fuel and what does it do?

Plant Mechanics LED Fuel is a late-flower additive designed to enhance trichome production, aroma, flavour, and colour—especially under high-intensity LED lighting. It's not a typical PK booster, but a finishing tool aimed at improving quality in the final bloom phase.

Is Plant Mechanics LED Fuel only for LED lights?

It’s optimized for LED and full-spectrum PAR lighting but can still help under other grow lights. It’s also compatible with all growing systems—soil, coco, hydro, DWC, RDWC, and autopots—when properly mixed and applied.

When should I use Plant Mechanics LED Fuel and how often?

Start around week 4 or 5 of flowering and use it through to the final week before your flush. Weekly applications are a safe approach. Avoid using it during veg or on young plants—it’s designed strictly for the bloom phase.

How much Plant Mechanics LED Fuel should I use?

Use 2ml per 1L of water. For example: 20ml in a 10L tank or 200ml in a 100L tank. Shake the bottle well before use. Add it to water first, then mix in your base nutrients and additives, check EC, and adjust pH last.

Does Plant Mechanics LED Fuel affect EC or pH?

Yes—it can slightly raise EC and tends to push pH alkaline. Always monitor both. If your feed is already strong, consider trimming base nutrients slightly to keep EC in range. pH your mix back down as needed.

Can I use Plant Mechanics LED Fuel with other nutrients and additives?

Yes. It works with most base nutrients, Cal-Mag, and silica—but mix each component into water separately. Avoid stacking too many late-stage boosters unless you’re closely monitoring EC and plant response.

What kind of results should I expect from Plant Mechanics LED Fuel?

Look for increased frost/trichome coverage, stronger aromas, richer colour, and a more finished look. Some results show within 7–14 days, with flavour and terpene expression becoming more noticeable toward the end or after curing.

What if I’m not seeing results with Plant Mechanics LED Fuel?

Check your light intensity, genetics, night temps, and pH. Many “frost” issues are caused by weak lighting or pH drift, not the product itself. LED Fuel enhances quality, but only if the rest of your grow is dialled in.

Is Plant Mechanics LED Fuel safe for edible crops and organic-style grows?

It contains botanical extracts and is widely used on fruiting and flowering edibles. However, it's not certified organic. Use it sensibly and follow your certifier’s input rules if growing organically.

How should I store Plant Mechanics LED Fuel?

Store sealed in a cool, dry place out of direct sunlight. It has a mild nutrient smell and should be handled with care—avoid contact with eyes or skin and wash hands after use. Keep out of reach of children and pets.

What size LED Fuel should I buy: 250ml, 1L, or 5L?

250ml is great for trials or small grows. 1L is ideal for most home growers running weekly feeds. 5L is the best value for larger gardens, multiple cycles, or commercial setups using bigger reservoirs.
