Growth Technology FOLIAR - 4.4 litre + Free trigger spray attachment

$59.00 NZD

New from Growth Technology (GT), comes the next step in plant nutrition. GT Foliar puts foliage growth on the fast track by feeding the leaves for more immediate nutrient uptake. Includes Silica to strengthen and protect, plus organic-based bio-stimulants for next level growth. All this in a ready to use spray, with a wetting agent as the base to create a finer mist, for better leaf coverage and improved absorption for foliar (leaf) feeding.

Note: GT Foliar supplements your usual fertiliser routine, not replaces it. For best results use GT Foliar leaf spray in addition to your usual soil fertiliser, such as GT Foliage Focus. 


This 4.4 litre size is a special order product. It will normally be sold out. If the button above says ADD TO CART it is in stock now, here in NZ, ready to ship. However, if it says NOTIFY ME please contact us and I can place an indent order for you (a deposit is required for special order products). 

When do plants benefit from GT Foliar?


When a plant is under stress or needing support for faster recovery (especially following root damage such as repotting or root rot).


When you need to quickly correct nutrient deficiencies in plants showing deficiency symptoms such as chlorosis (yellowing of normally green leaves). 


Or if you simply want to fast track foliage growth and push your plants for maximum growth.

Keep feeding!

It's recommended to mix-fed GT Foliar with your usual soil fertiliser such as GT Focus to help refuel and continue the rapid increase in growth. GT Foliar does not replace your usual soil fertiliser. 

    What's in GT Foliar?

    I haven't found anything that comes close to the combination and benefits of what's in GT Foliar. This clever formula has to be the simplest way to support recovery and supercharge growth. Plus all these benefits for our plants and it's ready to use straight from the bottle and comes with the spray trigger top included. Lucky plants. Lucky plant parents!

    💪 SILICA

    Known as Nature’s Bodyguard for the natural protective benefits silica offers plants, especially plants under stress. Silica is abundant outdoors, but deficient indoors. Strengthens and protects, including reducing browning in weak areas such as variegation and aiding protection from and recovery from pests and disease. 


    20 different Amino Acids. Organic plant proteins involved in multiple plant growth processes, including supporting proper photosynthesis.

    🌱 KELP

    3 types of Kelp. Naturally rich in plant growth hormones auxins, cytokinins and gibberellins. Nature's superfood for plants. Higher in trace elements and calcium than seaweed. Over 70 essential and beneficial minerals, vitamins and enzymes.


    Naturally golden in colour, fulvic acids are organic electrolytes that stimulate growth and improve plant health.  

    What does GT Foliar do for plants?

    The better question might be 'What doesn't GT Foliar do?' I know it sounds like a plant superfood, but do keep in mind GT Foliar is a growth booster, designed to supplement but not replace your root fertiliser.

    • Increases nutrient absorption to help correct deficiencies.
    • Aids recovery from common biotic and abiotic plant stresses, such as root rot and pest attack.
    • Increases speed and size of leaf growth.
    • Keeps up with increased nutrient demands during high growth periods.
    • Increases resistance to pests and diseases.
    • Reduces bud blast and premature browning.
    • Fuels production of more and healthier buds and flowers.
    • Minimises losses due to poor root performance or root damage.
    • Boosts overall growth and plant vigour.

    GT Foliar directions for use

    How much?

    GT Foliar comes in a ready-to-use 1/2 litre trigger pack (500mls) or ready-to-use 4.4 litre in bulk. No preparation required. Simply point and spray. Apply in cooler temperatures in low-light conditions as a fine mist to both tops and undersides of leaves. Avoid spraying blooms and buds. A very light covering is all that’s needed, top and bottom. Applying in the mornings or early evenings is best for uptake. In the hottest part of the day stomata are more likely to be closed (the 'pores' on plant's leaves), which reduces absorption.

    How often?

    Apply in times of stress, or as often as 2 to 3 times a week, to aid recovery for a plant under stress, or boost growth for a healthy plant. For boosting foliage growth, best applied during active, vigorous growth periods, when nutrient demand is high and leaves are more efficient at absorbing nutrients.

    Can be used throughout the plant’s lifecycle, from the cutting stage to blooming, to target all critical periods of growth as desired. Continue your usual root fertiliser regime, using GT Focus or your chosen fertiliser.
