Bloomroom Flexi-mat Reservoir Catchment Trays — Flexible Leak Protection for Tight Spaces
Best for: Growers in confined spaces who need reliable water containment without sacrificing portability or access
Our thoughts
This is proper secondary containment that actually solves a real problem — protecting your property from reservoir leaks without needing a massive rigid tray. The fact it folds flat and squeezes through tight doorways makes it dead handy for loft grows, small tents, and tight access points. One we recommend a lot for home growers who've been worried about spill damage.
The Bloomroom Flexi-mat is a flexible fabric catchment tray designed to contain leaks from your hydroponic reservoir, nutrient tank, or hand-watering setup. Unlike rigid plastic trays, the Flexi-mat folds completely flat for storage and transport, making it ideal for growers working in restricted spaces — lofts, small tents, tight doorways, anywhere a bulky tray won't fit. It's not a growing surface; it's peace of mind. The kind of thing you don't think you need until your reservoir springs a leak at 2am.
How it compares
This sits in a different category from traditional hard plastic grow trays.
-
Flexible fabric vs rigid plastic: Folds down to a fraction of the size, stores flat, fits through tight spaces. Rigid trays are more sturdy but bulky and immovable once installed
-
Secondary containment: The Flexi-mat's core job is leak containment, not primary growing. Rigid trays blur that line by trying to do both
-
Cost: Significantly cheaper than rigid commercial flood tables, with proper durability and waterproofing
-
System compatibility: Works seamlessly with Wilma, Autopot, IWS, and other large-reservoir systems where leak risk is highest
In short: if you need reliable leak containment in a space-constrained grow, the flexible approach wins every time.
Usage guidance
The Flexi-mat works across multiple setups:
Reservoir leak containment
Position your main nutrient tank or reservoir inside the tray. In the event of a leak, the Flexi-mat catches every drop, giving you time to fix the problem without water damage to floors, walls, or the space below.
Hydroponic system protection
House your entire ebb-and-flow system, flood table, or autopot setup inside the tray. This way, any leak from lines, connections, or pots is contained immediately. The integrated tap at the base lets you drain everything neatly without moving the whole setup.
Tight-space installation
Set it up in lofts, cupboards, sheds, or tight tent corners where rigid trays simply won't fit. Assemble the legs and feet in a few minutes, and you're done. When you need to move or store it, fold it flat and it takes up almost no space.
Optional growing surface
Some growers fill the Flexi-mat with substrate or use it as a catch tray for hand-watered pots. It's not ideal as a primary growing surface — that's not what it's designed for — but it works in a pinch if you need the flexibility.

Who this is for
- Home growers with confined or awkwardly-shaped growing spaces (lofts, cupboards, under-stairs)
- Tent growers who need secondary containment but have tight access points or doorways
- Anyone running large hydroponic systems (Wilma, Autopot, IWS) and genuinely worried about leak damage
- Growers who move or travel and need something portable and storable
- Budget-conscious growers who want leak protection without commercial flood table pricing
Not for permanent outdoor installations or heavy commercial setups — but perfect for the home grower who needs practical, flexible leak insurance.
Our take
This is a genuinely useful piece of kit that solves a real problem. Most people don't think about what happens if their reservoir leaks until it's too late. The Flexi-mat takes that risk off the table without eating up valuable grow space or costing a fortune.
The fact it folds flat and fits through doorways that a rigid tray never would makes it worth having. Good time to buy while stock lasts — especially if you're planning a new setup or upgrading your leak protection game.
