Ebb and Flood Systems

Save space & oxygenate roots – the compact, flexible Ebb & Flood System is here! Use it to grow 1 – 8 plants.

All plants sit together in one large tray filled with clay pebbles – you choose your own plant spacing.

To feed plants, nutrient solution floods the tray. When feeding ends, the solution is drained away. This traps oxygen in the root zone!

With all that oxygen, you get healthy roots, faster growth and a bigger yield! Better yet, most root diseases can’t survive in an oxygen rich environment either.

These little gems are super flexible. Grow several small plants or fewer large plants. Plant straight into the clay pebbles or keep crops in pots so you can move them around.

Either way, you’ll save tons of space and headroom… systems are self-contained and the biggest system’s only 33cm high! If you’ve got a low ceiling tent, this system’s perfect.

Top Tip

Keep your system sterile with Silver Bullet Roots. It kills 99.99% of root diseases and stays active in tanks for 5 weeks!

If you already use Oxy-Plus 11.9%, switch to Silver Bullet and you’ll save 55%.

When it’s time to feed, your nutrient fills the trays and pushes stale air out. During the flood, plants can absorb any nutrients or water they need.

When feeding ends, the flood pump switches off. A powerful vacuum is created to quickly pull nutrient solution back into your tank - along with a fresh dose of oxygen-rich air.

All that oxygen nourishes roots and improves growth. Most root disease can't thrive in an oxygen rich root zone either. 

Since clay pebbles don’t hold much water, roots have excellent access to oxygen between feeds! 

Feeding times for clay pebbles:

Start: 2 x 15 minutes feeds per day
Veg: 3- 4 x 15 minute feeds per day
Flowering: 4- 6 x 15 minute feeds per day

Feeding times for pots of coco/soil:

Start: 1 x 15 minutes feeds per day
Veg: 2- 3 x 15 minute feeds per day
Flowering: 3- 5 x 15 minute feeds per day

Feeding times for pots of 60/40:

Start: 2 x 15 minutes feeds per day
Veg: 3 x 15 minute feeds per day
Flowering: 4- 5 x 15 minute feeds per day
