Remo AstroFlower – 4 L

Remo AstroFlower is a 4-litre bloom additive built around fossilized organics. It is designed to work alongside Remo Micro, Grow, and Bloom base nutrients during the flowering phase, supporting bud development, essential oil production, and aromatic complexity by raising potassium and phosphorus availability at the plant level.

Why Choose Remo AstroFlower

AstroFlower fills a specific gap in the Remo lineup. The base three-part system (Micro, Grow, Bloom) covers the macro nutrition framework, but bloom additives like AstroFlower provide concentrated phosphorus and potassium at a stage when the plant is converting energy into flower mass and aromatic compounds. Here is what the canonical product description highlights:

• Purpose-built for the Remo system: AstroFlower is formulated to complement Remo Micro, Grow, and Bloom, fitting cleanly into the feed schedule without requiring macro-level adjustments.
• Fossilized organics as the delivery mechanism: The potassium and phosphorus are carried in a fossilized-organics base, which the manufacturer states targets bud development directly.
• Supports essential oil and aromatic production: Beyond yield, the product description notes assistance with the production of essential oils and aromatics — relevant for crops where terpene profile matters.
• Increases flowering potency: The formulation is described as assisting with increased flower production and increasing potency, both grounded in the product label.
• Works across growing media: Usable in soil, soilless, and hydroponic gardens, so the same 4 L bottle can move between different cultivation setups in the same facility.

Best Uses for Remo AstroFlower

AstroFlower is a late-vegetative and bloom-stage additive. Based on its category path (Nutrients & Additives › Additives › Growth & Bloom Boosters) and the product description, it is most useful in the following situations:

• Flowering-phase supplementation in hydroponic systems: Recirculating DWC, NFT, and flood-and-drain setups where raising available phosphorus and potassium during transition and peak bloom is straightforward via reservoir dosing.
• Coco coir and soilless grows: Coco is inert and relies entirely on what the grower adds; AstroFlower provides bloom-targeted K and P on top of a base program.
• Soil gardens where base nutrient programs are phosphorus-light: Some growers prefer to keep their base feed lean and supplement P-K with a dedicated booster like AstroFlower rather than switching to a high-P base.
• Growers running the Remo Nutrients three-part system: The product is specifically formulated to layer on top of Remo Micro, Grow, and Bloom without displacing ratios in the base program.
• Crops where terpene and essential-oil quality matters: The manufacturer notes assistance with essential oils and aromatics, so it is relevant for aromatic herb production and any crop where terpene density affects end value.

For root zone support alongside your bloom program, Heavy 16 Roots is a widely used root conditioner in the same Nutrients & Additives category. If you are looking for a carbon-based supplement to add alongside a bloom booster, Earth Juice Hi-Brix Molasses is another option in the same category.

Dosing Guidelines

The canonical product description does not include a specific millilitre-per-litre dose rate on the supplier listing. Remo Nutrients publishes a full feed chart on the Hydrofarm / Remo brand site that specifies AstroFlower dosing by week and growth stage. The following general guidelines apply to phosphorus-potassium bloom additives of this type:

• Introduce AstroFlower when plants transition into the flowering stage and continue through mid- to late-bloom, then taper or stop in the final flush week.
• Always add AstroFlower to your water or reservoir after your base nutrients (Micro, Grow, Bloom), not before, to avoid any precipitation of minerals before dilution.
• Check EC after adding all supplements; AstroFlower raises EC and should be accounted for in your total target EC for the week.
• Shake or invert the bottle before each use to ensure the fossilized-organics fraction is evenly distributed in the concentrate.
• Refer to the official Remo Nutrients feed chart (available at hydrofarm.com) for the week-by-week ml/L or ml/gal rate specific to your garden type and strain intensity.
