No pumps, no power, no timers — just gravity and a clever float valve that knows when to water and when to stop. Works with soil, coco, or hydroponic media. Simple, bulletproof, and it's been proven for over 20 years. One we recommend constantly for growers who want automation that actually makes sense.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eThe AutoPot 1-Pot System is a \u003cstrong\u003egravity-fed automatic watering system\u003c\/strong\u003e that grows a single plant in a 15-litre pot with zero electricity, zero maintenance headaches, and zero guesswork. At its heart is the AQUAvalve — a clever float valve that opens when the tray needs water and shuts off when it's had enough. The plant wicks nutrients from the shallow reservoir in the bottom of the tray and the valve responds automatically as the plant grows thirstier. That's it. No pumps to fail. No timers to programme. No power cuts to worry about. Just reliable, passive watering that scales from one pot to dozens.\u003c\/p\u003e\n\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eThis sits at the intersection of simplicity and automation — something most active systems (drip, NFT, DWC) can't touch.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs Active drip\/pump systems:\u003c\/strong\u003e No electricity, no timers, no pump maintenance.

Copper root control disc included.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe key difference: AutoPot responds to what the plant actually needs, not what a timer says. As your plant grows bigger and drinks more, the valve opens more frequently. As it slows down, so does the system.\u003c\/p\u003e\n\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003eThe AutoPot 1-Pot System works across different setups and growing media:\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGetting started\u003c\/strong\u003e\u003cbr\u003e\nHand-water for the first 10-14 days to establish the root system, then switch the system on. This gets plants off to a quicker start and prevents root rot in young seedlings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrowing media compatibility\u003c\/strong\u003e\u003cbr\u003e\nUse any free-draining substrate: soil, coco coir, 50\/50 soil\/coco mix, or hydroponic media. The key is light, fluffy, and absorbent — so the wicking works properly. Clay pebbles or perlite additions improve drainage further.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNutrient solution\u003c\/strong\u003e\u003cbr\u003e\nFill your header tank (sold separately) with any balanced nutrient solution — organic or mineral, it doesn't matter. The system gravity-feeds the solution into the tray, and the plant wicks it up as needed. No EC or pH adjustments required beyond what you'd normally do.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWater efficiency\u003c\/strong\u003e\u003cbr\u003e\nThe AQUAvalve fills the tray to exactly 20mm depth, then shuts off. Plants take what they need via wicking. No waste, no runoff — up to 50% water savings compared to hand watering or top-feed systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWet and dry cycle\u003c\/strong\u003e\u003cbr\u003e\nPlants experience a natural wet and dry cycle as the tray empties and refills. This is why they thrive — better oxygen availability at roots, stronger growth, and more prolific flowering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eScaling up\u003c\/strong\u003e\u003cbr\u003e\nThe 1-Pot System is modular. Link multiple pots to a single header tank using the included 4mm flexi-pipe and tee connectors. Each pot has its own AQUAvalve, so they all operate independently.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePot capacity: \u003cstrong\u003e15 litres\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePot type: \u003cstrong\u003eSquare plastic pot\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eTray dimensions: \u003cstrong\u003ePurpose-made AutoPot tray\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eWater depth per fill cycle: \u003cstrong\u003e20mm (controlled by AQUAvalve)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFloat valve: \u003cstrong\u003eAQUAvalve 5 (industry-standard)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePipe diameter: \u003cstrong\u003e4mm internal (6mm external)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncluded fittings: \u003cstrong\u003eFlexi-pipe, tee connectors, end caps\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eRoot control: \u003cstrong\u003eCopper disc in tray base\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePot protection: \u003cstrong\u003eMarix disc at pot base\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower requirement: \u003cstrong\u003eNone — gravity-fed only\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHeader tank: \u003cstrong\u003eSold separately (any height, any size)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMedia compatibility: \u003cstrong\u003eSoil, coco, hydroton, perlite, or mixed media\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNew growers who want automation without the learning curve of active systems\u003c\/li\u003e\n\u003cli\u003eExperienced growers looking to cut workload and water costs\u003c\/li\u003e\n\u003cli\u003eAnyone who travels or wants the option to step back from daily watering\u003c\/li\u003e\n\u003cli\u003eGrowers using soil or coco who find hand watering tedious\u003c\/li\u003e\n\u003cli\u003eBudget-conscious setups where electricity and pump maintenance aren't worth the hassle\u003c\/li\u003e\n\u003cli\u003eCommercial or semi-commercial operations wanting simple, proven, scalable automation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly well-suited to growers who want \u003cstrong\u003estraightforward reliability over technological complexity\u003c\/strong\u003e.

It's been proven for 20+ years, trusted by UK commercial growers, and does exactly one job brilliantly: feed plants automatically without fuss. No power cuts to worry about. No pump to service. No timer to reprogram. Just gravity and a valve that pays attention.\u003c\/p\u003e\n\u003cp\u003eIf you're hand-watering multiple plants or worried about overwatering, this cuts through the complexity and just works. You'll need a header tank (sold separately) to complete the system, but once you're set up, you're looking at mixing nutrients every few days instead of watering daily. That's freedom.\u003c\/p\u003e\n\u003cp\u003eGood time to grab this while stock lasts. One we sell a lot of, and one we genuinely rate.\u003c\/p\u003e\n\n\u003c\/section\u003e\n```","brand":"AUTOPOT","offers":[{"title":"Default Title","offer_id":47916520079530,"sku":"131000","price":28.49,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/5540\/5400\/files\/autopot_1-pot_system_excl_header_tank_1_17d264f1-e63d-4419-9302-daa30ce85de5.jpg?v=1769195106","url":"https:\/\/growershouse.co.uk\/products\/autopot-1-pot-system-excl-header-tank","provider":"Growers House ","version":"1.0","type":"link"}
