Collection: Recirculating Systems

Recirculating hydroponic systems continuously circulate nutrient solution past the plant roots instead of feeding on a timer, keeping oxygen and nutrients evenly delivered around the clock. A-Grade Hydroponics stocks two options: the GRO-TANK NFT for fast-growing lettuces and herbs, and ORIGIN Pot Systems, a deep water culture setup for larger fruiting plants like chillies and beefsteak tomatoes.

Recirculating systems for constant plant nutrition

Timer-based feeding schedules can leave roots waiting between cycles, and a poorly timed dry-out can stress plants fast. Recirculating systems solve this by keeping nutrient solution constantly moving, so roots get a steady, even supply of nutrients and oxygen without the fuss of a timer. This continuous feeding style tends to encourage extremely fast root growth, and maintenance is largely limited to standard cleaning and topping up nutrient concentration as it depletes.

What’s in this collection

GRO-TANK NFT — recirculating nutrient film technique system with a specially designed root mat, suited to the fast growth rates of lettuces and herbs

ORIGIN Pot Systems — recirculating deep water culture system built for larger, heavier-feeding plants like chillies and beefsteak tomatoes

How to choose

Recirculating systems suit both top-feed and Deep Water Culture setups, so the main decision is plant size and root demand. If you’re growing leafy greens or herbs and want fast, even root growth without managing a feed timer, the GRO-TANK NFT is a strong, low-fuss starting point — just mix your nutrients and top up as the solution depletes. If you’re growing larger fruiting plants like chillies or beefsteak tomatoes, ORIGIN Pot Systems gives each plant its own reservoir and more root space to support a bigger canopy. Both suit first-time hydro growers as much as experienced ones chasing higher yields.
