Flo Grow Double (All In One Grow System!)

How does the Flo Grow Double hydro system work?

Flo Grow Double is a timer-fed, top-drip recirculating system. A pump sends nutrient solution from the reservoir to a dripper ring, then it drains back down, pulling air through the roots for oxygen-rich feeding cycles throughout the day.

What are the main benefits of using Flo Grow Double?

Compared to hand-watering, it delivers more oxygen, more frequent feeding, and more consistent moisture—leading to faster growth, better nutrient uptake, and higher potential yields.

What comes with the Flo Grow Double system?

The kit includes a reservoir, planter, pump, dripper ring, and fittings. You’ll need to supply your own grow media (like coco or clay pebbles) and nutrients.

What grow media can I use with Flo Grow Double?

Coco, clay pebbles (LECA), or mixes of both work well. Coco holds more moisture; clay pebbles drain faster. Stick to one media type if you’re new, as mixed blends require more dialing in.

What types of plants is Flo Grow Double best for?

It’s ideal for larger or long-term plants, including fruiting crops, herbs, leafy greens, or mother plants. You can run one or two plants depending on size and style.

Do I need a timer for Flo Grow Double?

Yes. A digital cycle timer is recommended so you can schedule short, frequent feeds. Start with fewer, shorter feedings and increase as roots fill in and plants mature.

What nutrients and additives are safe to use?

Mineral hydroponic nutrients are easiest. You can use organics or microbes, but they may clog the pump and drippers, so regular cleaning and filtration are important if you go that route.

Do I need to monitor pH and EC in Flo Grow Double?

Absolutely. pH affects nutrient uptake, and EC tracks solution strength. If you buy one tool, get a pH meter first—accuracy here is critical in hydro setups.

How do I manage the reservoir and water changes?

Top up with plain water, then recheck pH and nutrients. Change the solution weekly or sooner if pH drifts or the reservoir gets dirty. Water temperature should stay cool and stable for healthy roots.

Does Flo Grow Double need an air stone or make noise?

An air stone isn't required but can help with oxygenation. The system is quiet; any noise is usually pump vibration, which can be fixed with a foam pad under the pump.

Can I use Flo Grow Double indoors or outdoors?

Yes. It’s commonly used indoors for automation and compact footprint. Outdoors, you’ll need to protect it from rain, heat swings, and sunlight hitting the reservoir to avoid algae.

How do I prevent clogs, uneven feeding, or algae growth?

Use clean nutrients, filter additives, and clean regularly. Check the dripper ring for even flow and keep the reservoir shaded and sealed to block light and algae growth.

How often do I need to clean the system?

Wipe it down weekly and deep-clean between grows or when needed. Use a siphon or small pump for easier water changes. It’s not fully “set and forget,” but close with good habits.

Can I start seedlings in Flo Grow Double?

It's better to start seedlings separately and transplant once roots are developed. To avoid salt buildup, monitor EC, avoid overfeeding, and flush occasionally if using coco.

Is Flo Grow Double beginner-friendly and long-lasting?

Yes—it’s simple to automate, durable when maintained, and great for long-term plant cycles. Just learn the hydro basics (like pH, EC, and system hygiene), and you’re good to go.
