From our test beds

Honest note: filled with wet media this bed weighs several hundred pounds. Assemble and level it in its final location — you will not be sliding it over once it is planted.

FAQ

Questions, answered

Does it include growing media?

No — 32 cubic feet of clay pebbles is a lot to ship affordably, so we let you source it locally. The guide lists what to buy.

Can I use it above ground on a deck?

Full of wet media it is very heavy. Confirm your deck is rated for the load, or place it on grade.

The long read

Why we grow it this way

Production-scale growing

This is the grow bed built to pair with a 275-gallon IBC tank in a proper 1:1 ratio. A 4×8 ft flood-and-drain bed, twelve inches deep for real root run, on a stainless frame that shrugs off a decade of greenhouse humidity. The food-grade HDPE liner and included bell-siphon assembly turn fish water into a garden.

It holds 32 cubic feet of media — enough to grow fruiting crops, not just greens.

Built to last

The stainless frame is overkill in the best way. Two seasons in a humid greenhouse and zero rust. Bell siphon started cycling first try.

Great bed, buy media locally

Solid and deep enough for my tomatoes. Just know you supply the 32 cu ft of pebbles yourself — that adds up.
