CYCO Swell – 5 Liter

CYCO Swell is a phosphorus, potassium, and magnesium bloom booster formulated for use during the later flowering stages of plant growth. Phosphorus supports photosynthesis and assists with plant maturation and stress tolerance; potassium enhances fruit quality; and magnesium activates the plant enzymes needed to drive growth. CYCO Swell is available in a 5 Liter size suitable for medium to large grow operations.

Why Choose CYCO Swell

CYCO Swell is designed to address the specific nutritional demands plants have during the bloom phase. The three active nutrients each play a distinct role in supporting a successful harvest:

• Phosphorus for photosynthesis and maturation: The phosphorus in CYCO Swell plays an essential part in photosynthesis. It assists with plant maturation and aids in withstanding environmental stress, which can be particularly relevant in the final weeks of flowering when plants are producing dense, heavy blooms.
• Potassium for fruit quality: Potassium is known to enhance the quality of fruits and flowers. Including an adequate potassium source during bloom supports the development of dense, well-formed produce.
• Magnesium to activate growth enzymes: Magnesium is a cofactor in numerous enzymatic reactions within the plant. CYCO Swell supplies magnesium to help activate the plant enzymes needed for continued growth during the flowering period.
• Targeted for later flowering: CYCO Swell is specifically recommended for use in the later flowering stages, making it a complement to a broader feeding program rather than a standalone nutrient — it is intended to be added when a targeted P-K-Mg boost is most beneficial.
• Liquid concentrate format: As a liquid concentrate, CYCO Swell mixes readily into reservoir water or foliar-spray solutions and integrates with the broader Cyco Platinum Series feeding schedules.

Best Uses for CYCO Swell

CYCO Swell is a Growth & Bloom Booster additive designed for growers who are already running a complete base nutrient program and want to provide additional P-K-Mg support during the bloom phase. It fits the following scenarios well:

• Late-flowering supplementation: Add CYCO Swell to your feeding program during the final weeks of the flowering cycle, when phosphorus and potassium demand typically rises and plants are building final fruit weight.
• Stress recovery during bloom: If plants have experienced environmental stress — temperature swings, humidity issues, or irrigation irregularities — the phosphorus in CYCO Swell can help them recover and continue maturing without significant yield loss.
• Hydroponics and soilless systems: As a precision liquid additive, CYCO Swell is well-suited for recirculating hydroponic systems, coco coir, and other soilless substrates where nutrient uptake is direct and measurable.
• Pairing with root health products: For growers running root zone additives such as Heavy 16 Roots alongside a bloom program, CYCO Swell provides the above-canopy P-K-Mg complement to complete the late-stage feeding stack.
• Growers following Cyco Platinum Series schedules: CYCO Swell is part of the Cyco Platinum Series product line. Growers already using other Cyco nutrients will find it integrates directly into published Cyco feed charts.
• Medium to large scale cultivation: The 5 Liter size is suited for commercial and semi-commercial grows where purchasing concentrate in bulk reduces per-gallon cost and packaging overhead compared to smaller sizes.

Usage Guidelines for CYCO Swell

CYCO Swell is a liquid nutrient additive used during the later stages of the flowering cycle. Follow the general application guidelines below, and always refer to the current Cyco Platinum Series feed schedule for exact dose rates by week:

• When to start: Introduce CYCO Swell during the later flowering weeks as specified on the Cyco feed chart — typically once flower sites are well-established and plants have transitioned fully into the bloom phase.
• Measuring: Shake or stir the concentrate before measuring. Use a calibrated syringe or measuring cup to portion the correct volume per litre or gallon of reservoir water.
• Mixing order: Add CYCO Swell to your reservoir after base nutrients and before pH adjustment. Mix well and allow the solution to circulate before taking a final pH and EC reading.
• Target EC: Verify total solution EC is within the appropriate range for your crop’s flowering stage. Adjust total feeding rates — not just CYCO Swell dose — if EC is above target.
• pH range: Maintain reservoir or media pH in the range appropriate for your growing system (typically 5.8–6.2 for hydroponics and coco coir; 6.0–6.5 for soil). CYCO Swell does not replace pH management.
• Monitoring: Observe plant response over 2–3 days following introduction. Healthy dark green foliage with continued bloom development indicates the dose is appropriate. If leaf tips show signs of tip burn or nutrient excess, reduce total feed concentration before modifying CYCO Swell dose in isolation.

For growers evaluating complementary nutrient inputs for the vegetative and early root phase, Advanced Nutrients Tarantula is a microbial inoculant that supports root zone development and can be run earlier in the grow cycle ahead of a bloom additive like CYCO Swell. Similarly, PureCrop1 is a foliar concentrate some growers apply alongside bloom programs for canopy health management.
