Dr Greenthumbs Fruit Roids (Organic Flowering Enhancer)

A 100% organic, water-soluble flowering enhancer for coco and soil. It delivers minerals, amino acids, enzymes, and plant-based growth hormones to boost flower set, density, oils & terpenes, and overall plant health. It also supports thicker cell walls (sturdier stems/leaves) and natural resistance to pests and mould thanks to salicylic acid, chitosan, and phytohormones.

Yep. It’s loaded with complex carbohydrates that feed the root-zone biology and play nicely with mycorrhizae. Soil-friendly and coco-friendly.

• Veg (pre-flip boost): ½ tsp per litre, once, about 7 days before flip
• Flower: ½–1 tsp per litre, once weekly
• Sick/unhappy plants: ¼–½ tsp per litre; apply twice, 7 days apart (pairing with Root Roids is ideal)
  Mix well, keep it agitated, and pH after adding.

• Coco: Use until you begin your flush.
• Soil: Use until the last week of flower.

Hand-watering gives the most consistent results. If you must run it via irrigation: drop the tank volume to the minimum, add Fruit Roids, water to 5–10% runoff, and don’t store it in the reservoir. Discard leftovers after 24 hours and always mix fresh.

It’s partly micronised so foliar is possible, but you may need extra filtration to avoid sprayer blockages. Most growers just hand-water for ease and consistency.

A heaped ½–1 teaspoon per litre of water, once per week in flower. Mix into your watering can thoroughly (don’t try to pre-mix it into dry soil).

It’s designed to simplify bloom support—often replacing separate silica, seaweed/kelp, enzyme, and “natural PGR” products in many setups without sacrificing performance.

A proprietary blend of natural enzymes, plant-based growth hormones (cytokinin, gibberellin), minerals, amino acids, and complex carbohydrates.

Yes. Run it alongside your normal base feed. Dose Fruit Roids on its own watering (or keep the solution well agitated) and pH after adding.

Use the same rates. The only tweak is when you stop (coco stops at flush; soil stops in the final week). If you’re running high-frequency fertigation, most growers keep Fruit Roids as a separate weekly hand-water instead of parking it in a big reservoir.

A gentle dose (¼–½ tsp/L) can help nudge biology back on track. Avoid heavy flushing that can cause over-watering stress—let the plant recover and reintroduce nutrition gradually.

Not recommended. If you do foliar, keep concentrations low, pre-filter thoroughly, and treat foliar as a supplement—root application is the main event.

It isn’t designed for long-term reservoir storage. In recirculating or drip systems, treat it as a freshly mixed pulse (see irrigation notes) to avoid precipitation or bio-loading in lines.

Give a one-off ½ tsp/L watering about a week before flip to prime plants. At transplant, keep media evenly moist (not waterlogged) to minimise stress.

100 g, 225 g Pro Pack, 1 kg. As a rough guide, a 100 g pack treats up to ~40 L at ½ tsp/L dosages.

Both. It’s formulated to lift yield and oil production while improving branching (more sites) and structural strength for denser flowers.

Mix vigorously, keep it agitated during application, and don’t let mixes sit—make fresh each time. If you absolutely must hold a mix briefly, discard after 24 hours.
