Engineered for the specific PAR requirements of early plant development, it delivers controlled low-intensity output that prevents stretch, supports root initiation, and keeps growth compact from germination through to transplant.\u003c\/p\u003e\n\u003ch3\u003eTargeted Spectrum for Early Growth\u003c\/h3\u003e\n\u003cp\u003eThe FLEX II outputs a balanced spectrum weighted toward blue wavelengths (400–500nm) to drive compact vegetative structure and root development, with red wavelengths supporting early photosynthesis. Tuned specifically for propagation — not adapted from a full-cycle fixture.\u003c\/p\u003e\n\u003ch3\u003eLow-Watt Precision — 10W \u0026amp; 20W Options\u003c\/h3\u003e\n\u003cp\u003eExcess light intensity is the leading cause of clone failure. The FLEX II operates at 10W or 20W, designed for close-range placement (10–20cm) without heat stress or light bleach. Consistent output across the full tray with no intensity spikes.\u003c\/p\u003e\n\u003ch3\u003eBar Design — Uniform Light Distribution\u003c\/h3\u003e\n\u003cp\u003eSingle-point light sources create hotspots that cause uneven germination and inconsistent rooting. The bar format distributes light evenly across the entire propagation tray — every seedling and cutting receives the same PPFD.\u003c\/p\u003e\n\u003ch3\u003eClose-Range Efficiency\u003c\/h3\u003e\n\u003cp\u003ePositioned close to the canopy, the FLEX II maximises photon delivery at the plant surface. Lower wattage at the right distance outperforms high-powered lights hung too far away — better results with less energy.\u003c\/p\u003e\n\u003ch3\u003eWhy Experts Choose SANlight\u003c\/h3\u003e\n\u003cp\u003eThe FLEX II is daisy-chain ready via the included splitter link cable, allowing multiple bars to run off a single power adapter. Commercial clone rooms can scale the system without additional power points or controllers.\u003c\/p\u003e\n\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2 × FLEX II propagation bars\u003c\/li\u003e\n\u003cli\u003e1 × splitter link cable (daisy-chain ready)\u003c\/li\u003e\n\u003cli\u003e1 × power adapter\u003c\/li\u003e\n\u003cli\u003e1 × travel adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAvailable Sizes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10W FLEX II — 547mm:\u003c\/strong\u003e Small propagation trays, hobby growers, compact clone domes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20W FLEX II — 995mm:\u003c\/strong\u003e Larger trays, commercial nurseries, high-volume propagation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy are my seedlings leggy and stretched?\u003c\/h2\u003e\n\u003cp\u003eStretching occurs when seedlings receive insufficient light intensity or poorly distributed output during germination. The plant elongates searching for adequate PAR. The FLEX II placed 10–20cm above the canopy delivers the right intensity to keep internodal spacing tight and stems strong.\u003c\/p\u003e\n\u003ch2\u003eHow far should SANlight FLEX II be from clones?\u003c\/h2\u003e\n\u003cp\u003ePosition FLEX II bars 10–20cm above cuttings. This range delivers optimal low-intensity PAR for root initiation without triggering heat stress or light bleach — the two primary causes of clone failure at propagation stage.\u003c\/p\u003e\n\u003ch2\u003eBest LED spectrum for plant propagation\u003c\/h2\u003e\n\u003cp\u003ePropagation requires higher blue (400–500nm) ratios to suppress stretch and promote root development, with red wavelengths (600–700nm) supporting photosynthetic efficiency. The FLEX II spectrum is calibrated for this stage specifically — not a full-cycle white LED approximation.\u003c\/p\u003e\n\u003ch2\u003ePerfect for\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSeed germination\u003c\/li\u003e\n\u003cli\u003eClone propagation and cuttings\u003c\/li\u003e\n\u003cli\u003eIndoor plant nurseries\u003c\/li\u003e\n\u003cli\u003eHydroponic propagation setups\u003c\/li\u003e\n\u003cli\u003eGrow tents and dedicated propagation areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePlant effects from the FLEX SET LED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFaster, more even germination across the tray\u003c\/li\u003e\n\u003cli\u003eCompact seedlings with tight internodal spacing\u003c\/li\u003e\n\u003cli\u003eHigher clone rooting success rates\u003c\/li\u003e\n\u003cli\u003eLess plant loss during the propagation stage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eHow far should SANlight FLEX II Set be from seedlings and clones?\u003c\/h3\u003e\n\u003cp\u003eFor seedlings and fresh clones, position SANlight FLEX II Set 30–60cm above the canopy to provide gentle, even light distribution without heat stress. As plants develop and roots establish, lower the light progressively or increase intensity to drive stronger vegetative growth. Avoid high-intensity light on fresh unrooted cuttings as this increases transpiration stress before roots are established to supply water.\u003c\/p\u003e\n\u003ch3\u003eHow many hours of light per day should I run SANlight FLEX II Set during propagation?\u003c\/h3\u003e\n\u003cp\u003eRun SANlight FLEX II Set on an 18\/6 or 20\/4 schedule during propagation and vegetative growth. Continuous light (24\/0) is sometimes used in commercial propagation to maximise rooting speed but can stress some genetics. An 18-hour photoperiod is the safest starting point for most crops and avoids the diminishing returns of continuous illumination.\u003c\/p\u003e\n\u003ch3\u003eDoes SANlight FLEX II Set ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — SANlight FLEX II Set ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.\u003c\/p\u003e","brand":"SANlight","offers":[{"title":"20 Watt Set","offer_id":43149271826495,"sku":null,"price":229.95,"currency_code":"AUD","in_stock":true},{"title":"40 Watt Set","offer_id":43149271859263,"sku":null,"price":349.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/files\/FLEX-II-CC-Wagon-near_1000x1000_Grey-copy_85bd9ce9-23da-4a8c-97e6-c8e22cb12016.png?v=1776841834","url":"https:\/\/apexgrow.com.au\/products\/sanlight-flex-ii-led-propagation-light-seedlings-clones-australia","provider":"Apex Grow","version":"1.0","type":"link"}
