Roots do most of a plant's feeding, but leaves take up nutrients too, and a leaf spray puts a top-up straight where you can see it working. GT Foliar is Growth Technology's ready-to-use leaf feeder: a full mineral profile, 20 amino acids, three types of kelp, fulvic acid and silicon, with a wetting agent that helps the spray into the leaf instead of beading and running off. There is nothing to mix. Mist the tops and undersides of the leaves in low light, two to three times a week, on anything from cuttings to mature plants, indoors or out. It runs alongside your root feed rather than replacing it, and it stays off the flowers. Available as a 500ml trigger spray or a 5.5L pack.

Ready to use. Keep it off the flowers. Mist, don't drench: Growth Technology says soaking the plant reduces how much it absorbs. Spray in low light, and keep it off open and developing flowers, which GT warns can rot when wet.
No mixing, no measuringReady to use straight from the pack. Pick up the trigger bottle and spray: there is no concentrate to dilute and no rate to get wrong.
More than a mineral sprayA full mineral profile plus 20 amino acids, three types of kelp, fulvic acid and silicon in one bottle. Most leaf sprays carry one or two of those.
Wetting agent built inGrowth Technology adds a wetting agent so the spray spreads across the leaf instead of beading and rolling off, helping the solution into the plant tissue.
Cuttings to mature plantsListed by Growth Technology for propagation, cuttings, vegetative, flowering and mature stages, indoors and out, in soil, semi-hydro or hydro.
Two to three sprays a weekGT's guide is two to three applications a week, stepping up to daily while plants are in strong, vigorous growth and demand is high.
Kelp for fruit setGrowth Technology formulates the three-kelp blend, with its naturally occurring auxins, cytokinins and gibberellins, to support fruit set and yield.

Grower's Tip
  • Low light means early morning, late afternoon, or with the grow lights dimmed. GT's reasoning: in hot, bright conditions the leaf pores are mostly closed, so the spray is wasted.
  • Get the undersides. Growth Technology's direction is tops and undersides of the leaves, and the underside is the side most people miss.
  • Fine mist, then stop. Once droplets start running off the leaf you have done enough; GT says drenching reduces how much the plant takes in.
  • Keep it off open and developing flowers. Shield them with your hand, or leave a plant in full bloom out of the round.
  • It is a leaf feed on top of your root feed, not instead of it. Keep feeding the pot or reservoir as normal.
  • Running a big collection? Keep the 500ml trigger bottle and top it up from the 5.5L pack.
  • Store it somewhere cool and dark.

How To Use It
1Pick a low-light time to spray: early morning, late afternoon, or with the grow lights dimmed.
2Set the trigger to a fine mist and spray the tops and undersides of the leaves.
3Stop when the leaves are evenly covered, before the spray runs off. Do not drench the plant.
4Keep the spray off open and developing flowers.
5Repeat two to three times a week, or daily while plants are in strong, vigorous growth.

Frequently Asked Questions
Do I need to dilute GT Foliar?

No. It is ready to use. Spray it straight from the pack.

How often should I use it?

Two to three times a week, which is Growth Technology's guide. During periods of vigorous growth, when demand is high, GT says it can go on daily.

Can I spray it on flowers?

No. Growth Technology warns against spraying open and developing flowers, which can rot when wet. Spray the leaves only.

When is the best time to spray?

In low light: early morning, late afternoon or with the grow lights dimmed. GT says spraying in hot, bright conditions is wasted effort because the leaf pores are mostly closed.

Does it replace my normal nutrient?

No. It feeds through the leaves alongside your root feed. Keep feeding the pot or reservoir as normal.

Can I use it on cuttings and seedlings?

Yes. Growth Technology lists it for propagation and cuttings as well as vegetative, flowering and mature plants. Use a fine mist and keep it light.

Is GT Foliar a pest-control product?

No. It is a leaf feed, not a registered pest-control product. If you have a pest problem, use a product registered for that pest.

What is in GT Foliar?

A full mineral profile, 20 amino acids, three types of kelp, fulvic acid, silicon and a wetting agent. Growth Technology does not publish a guaranteed analysis, so we do not list one.

Which size should I buy?

The 500ml trigger spray suits a shelf of houseplants or a small tent. The 5.5L is for refilling the trigger bottle or a pressure sprayer across a bigger collection.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
