Phosphorus drives energy transfer and maturation, and the potassium and magnesium alongside it support the movement of sugars into the flower as the plant finishes.\u003c\/p\u003e\n\n\u003ch2\u003eSwell or Potash Plus, and Why Not Both\u003c\/h2\u003e\n\u003cp\u003eThese two get confused constantly, so here's the plain version. Both are PK additives. The difference is which way the ratio leans and when in flower you run them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePotash Plus is 0-4-6.\u003c\/strong\u003e More potassium than phosphorus, and it runs in the first half of flower, roughly weeks 1 to 4, while the plant is still setting and building.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSwell is 1-5-3.\u003c\/strong\u003e More phosphorus than potassium, and it runs in the second half, roughly weeks 5 to 7, once flowers have set and the job shifts to filling them out.\u003c\/p\u003e\n\u003cp\u003eCYCO's own label on both bottles says not to use them in conjunction with each other. That isn't a compatibility warning about the chemistry, it's a dosing one. Run both in the same reservoir and you're stacking two PK products on top of whatever PK is already in your base nutrient, which pushes phosphorus well past what the plant can use. Excess phosphorus competes with iron and zinc uptake, which is a common way growers end up chasing an iron deficiency in late flower that started as overfeeding.\u003c\/p\u003e\n\u003cp\u003eRun them in sequence, not together. Potash Plus early, Swell late, and follow the feed chart for the changeover.\u003c\/p\u003e\n\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight and Bulk:\u003c\/strong\u003e Phosphorus at 5% supports the energy transfer behind flower fill in the finishing weeks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSugar Movement:\u003c\/strong\u003e Potassium at 3% drives phloem transport, moving sugars from the leaves into the flower.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnesium Included:\u003c\/strong\u003e 1% magnesium, the central atom in every chlorophyll molecule, which matters late in flower when lower leaves are already fading.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage Specific:\u003c\/strong\u003e Formulated for the last few weeks rather than the whole cycle, so you're not carrying high phosphorus through veg.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow and When to Use\u003c\/h2\u003e\n\u003cp\u003eStart Swell once flowers have set and the plant has moved past the building stage, roughly week 5 of a standard flowering cycle. Run it as part of your normal feed alongside your base nutrient, and stop running Potash Plus when you start.\u003c\/p\u003e\n\u003cp\u003eWatch total EC when you add it. Swell contributes to the number, and pushing your feed too high in late flower causes more problems than a slightly lower phosphorus level would. If you're seeing dark, glossy, clawed leaves after adding it, that's excess rather than shortage, and the fix is to back off rather than push through.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Liquid additive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuaranteed Analysis:\u003c\/strong\u003e Total Nitrogen 1%, Available Phosphate (P2O5) 5%, Soluble Potash (K2O) 3%, Magnesium 1%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDerived From:\u003c\/strong\u003e Potassium nitrate, monopotassium phosphate, magnesium nitrate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media:\u003c\/strong\u003e Hydroponics, coco coir, and soil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest Used:\u003c\/strong\u003e Second half of flowering, roughly weeks 5 to 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDo Not Combine With:\u003c\/strong\u003e CYCO Potash Plus in the same feed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse Alongside:\u003c\/strong\u003e Any CYCO Platinum Series or Commercial Series base nutrient\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eAvailable Sizes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1L\u003c\/li\u003e\n\u003cli\u003e5L\u003c\/li\u003e\n\u003cli\u003e20L Commercial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eCYCO Swell is a pharmaceutical grade, Australian made phosphorus-weighted additive for the finishing weeks of flower.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eCan I use CYCO Swell and Potash Plus together?\u003c\/h3\u003e\n\u003cp\u003eNo. Both bottles carry a label warning against using them in conjunction, and the reason is dosing rather than chemistry. They're both PK additives running on top of a base nutrient that already contains PK, so stacking them overshoots phosphorus badly. They're also built for different weeks, Potash Plus for weeks 1 to 4 of flower and Swell for weeks 5 to 7. Run them in sequence instead.\u003c\/p\u003e\n\u003ch3\u003eWhat's the actual difference between Swell and Potash Plus?\u003c\/h3\u003e\n\u003cp\u003eThe ratio and the timing. Potash Plus is 0-4-6, so more potassium than phosphorus, and it runs early in flower. Swell is 1-5-3, so more phosphorus than potassium, and it runs late. Neither is a pure single-element product, which is why the ratio is the thing to look at rather than the name.\u003c\/p\u003e\n\u003ch3\u003eWhen should I start using CYCO Swell?\u003c\/h3\u003e\n\u003cp\u003eOnce flowers have set and are developing, roughly week 5 of a standard flowering cycle. Starting it earlier means running high phosphorus at a point where the plant still wants potassium for building, which is what Potash Plus is for.\u003c\/p\u003e\n\u003ch3\u003eCan I use CYCO Swell alongside Suga Rush or Supa Stiky?\u003c\/h3\u003e\n\u003cp\u003eYes. Swell is commonly run with other late-flowering additives such as Suga Rush and Supa Stiky, none of which carry a conflict warning. Follow the dose for each and watch total EC, since three additives on top of a base feed adds up faster than growers expect.\u003c\/p\u003e\n\u003ch3\u003eCan I use CYCO Swell in soil as well as hydroponics?\u003c\/h3\u003e\n\u003cp\u003eYes. Soil buffers nutrients, so start at a reduced rate and adjust based on how the plant responds.\u003c\/p\u003e\n\u003ch3\u003eWhat is the shelf life of CYCO Swell?\u003c\/h3\u003e\n\u003cp\u003eUnopened, 2 years when stored cool and out of direct sunlight. Once opened, use within 12 months. Shake well before each use as some formulations settle.\u003c\/p\u003e\n\u003ch3\u003eDoes CYCO Swell ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes, CYCO Swell ships from within Australia with fast tracked delivery Australia-wide. Most east coast orders arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.\u003c\/p\u003e","brand":"CYCO","offers":[{"title":"1L","offer_id":43766872473663,"sku":"CYCO-SWELL-1L","price":56.95,"currency_code":"AUD","in_stock":true},{"title":"5L","offer_id":43820328779839,"sku":"CYCO-SWELL-5L","price":194.95,"currency_code":"AUD","in_stock":true},{"title":"20L","offer_id":43820328812607,"sku":"CYCO-SWELL-20L","price":609.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/files\/swell.jpg?v=1787569559","url":"https:\/\/apexgrow.com.au\/products\/cyco-platinum-series-swell-late-flowering-weight-and-bulk-additive-australia","provider":"Apex Grow","version":"1.0","type":"link"}
