You hand water as usual, but the brain bucket pumps away run-off automatically before it turns your root zone into a swamp. Proper system that solves real problems — pythium, root rot, humidity spikes — and doesn't cost the earth.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eThe IWS AutoDrain System is a \u003cstrong\u003erun-to-waste drainage solution\u003c\/strong\u003e that removes excess nutrient run-off automatically, keeping your root zone oxygenated and healthy. Hand water your plants normally. The flexi-pipe feeds run-off into the brain controller. When the float sensor detects liquid, the pump fires and everything drains to waste. Simple, reliable, and it means you're not gambling with stagnant water anymore.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eThis sits in the \u003cstrong\u003emodular, hand-watering-friendly\u003c\/strong\u003e bracket of drainage systems.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMore affordable entry point than all-in-one Medusa or FloraFlex complete kits\u003c\/li\u003e\n\u003cli\u003eModular design — start small, scale up by adding more trays to the same brain\u003c\/li\u003e\n\u003cli\u003eDesigned for hand watering, not drip automation (though you can upgrade later)\u003c\/li\u003e\n\u003cli\u003eFocuses on the thing that actually matters: getting run-off away from roots fast\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUnlike Medusa's integrated approach or FloraFlex's platform systems, this one lets you keep full control over feeding while removing the labour of manual draining.\u003c\/p\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDay-to-day watering\u003c\/strong\u003e\u003cbr\u003ePlace pots on the large drain trays. Hand water as normal, aiming for 20–30% run-off. The tray collects everything. When liquid pools in the brain controller, the mj1000 pump kicks in and pushes it straight to waste.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMonitoring and feeding\u003c\/strong\u003e\u003cbr\u003eCollect run-off samples before it drains. Check EC and pH to see what your plants are actually taking up. Adjust your next feed based on real data, not guesswork. This is where run-to-waste gets powerful — you're force-feeding the roots to search for water, which builds a proper root mass fast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRoom setup\u003c\/strong\u003e\u003cbr\u003eConnect the large trays to the brain controller using the supplied 13mm flexi pipe and fittings. Position the brain unit lower than the trays so gravity feeds into it. Route the discharge line to a drain or waste container. That's it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eScaling\u003c\/strong\u003e\u003cbr\u003eThe system handles multiple trays fed into one brain.
