Hydrodynamics International Root Riot 50-Cell Tray

A 50-Cell Tray of Root Riot Cubes for Consistent Propagation

Loose cubes still need a tray to sit in during propagation, so buying cubes and a tray insert separately means matching up sizes and tracking two line items. This kit pairs 50 Root Riot cubes with a matching tray insert, holding the same air-to-water ratio suited for propagating cuttings and starting seeds.

Sized at 50 cells, it's built for a single propagation run without needing to source cubes and a tray separately.

Key Features & Benefits

• 50 pre-loaded cells — cubes and tray insert sized to match, ready to use together
• Spongy, biodegradable cube texture — retains an air-to-water ratio suited to propagation
• Supports consistent root development — each cell holds the same growing conditions
• Suited to cuttings and seeds alike — one tray design covers both propagation methods

Who Should Use This Tray

Growers who want cubes and a matching tray in one kit, rather than sourcing a tray insert separately, will use this 50-cell Root Riot tray for a propagation run.

Frequently Asked Questions

How do I use this tray kit?

Insert a cutting or seed into each of the 50 pre-formed cube holes, then keep the tray in a humidity dome or covered area during propagation. The cubes and tray insert are sized to match, so there's no separate fitting to figure out.

How is this different from buying a bag of cubes separately?

A bag of loose cubes still needs a tray to sit in, while this kit includes both the 50 cubes and the matching tray insert together. That's convenient for a grower who doesn't already have a compatible tray on hand.

Can I reuse the tray insert after the cubes are used up?

The tray insert can be reused with a fresh bag of Root Riot cubes once the current batch has finished propagating. Replace the cubes themselves each propagation cycle since they're a single-use biodegradable medium.

Does this tray work for both cuttings and seeds?

Yes, the same 50-cell cube design is suited to propagating cuttings and starting seeds, so a single tray can be used for either. Mixing both in the same tray run is also possible since each cell is independent.
