Multi Pot Mega Pot System (4 x 16 Litre) - One Valve Feeding Four Plants
Best for: Growers running four plants on shorter cycles who want gravity-fed watering across the whole bank from a single valve.
Our thoughts
This is the multi-plant version of the single Mega Pot Grow System we also stock, four 16 litre pots run off one MegaValve instead of one valve per pot. If you're running a shorter-cycle crop across four plants, this is the more efficient way to plumb it, less valves to maintain, one feed point to manage. Reliable performance at a sensible price.
The Multi Pot Mega Pot System is a 4-pot, 16 litre gravity-fed setup built for growers who run shorter plant cycles across multiple plants at once. Unlike the single Mega Pot module, which uses one MegaValve per pot, the Multi-Pot links all four 16 litre pots to a single MegaValve with a 10mm inlet, so one valve manages water delivery to the whole bank rather than four separate valves needing individual attention.
The base footprint measures approximately 80cm x 80cm, sized specifically around the four 16 litre pots, and the system is completely gravity fed with no electricity, pump or timer required. It scales the same way the single Mega Pot does, from one Multi-Pot module up to large multi-module banks feeding from a shared reservoir.
How it compares
Multi-pot gravity-fed systems are a proven category, with a couple of well-known alternatives.
- Versus AutoPot's Easy2Grow, which runs 2 pots per module in 8.5 or 15 litre sizes using individual AquaValves per pot, the Multi Pot Mega Pot runs 4 pots per module from a single shared valve, meaning less hardware to maintain per plant.
- Versus the single-pot Mega Pot Grow System, this is the same core technology scaled to feed four plants from one valve instead of a separate valve per pot.
- Versus a manual flood-and-drain table for the same plant count, the Multi Pot needs no pump or timer and runs continuously off gravity alone.
Four plants per valve means less plumbing and fewer parts that can fail compared with a valve-per-pot layout, at the cost of slightly less flexibility if you want to isolate one plant's watering from the others.
Usage guidance
Setup follows the same gravity-fed principle as the single Mega Pot, just scaled to four pots.
Layout
Plan for an 80cm x 80cm footprint and keep your reservoir elevated above the module so gravity can feed the shared valve.
Filling
Let the tray fill to its pre-set level via the single MegaValve before adding plants and medium to all four pots.
Cycle planning
Because it's built for shorter cycle plants, plan your crop rotation around quicker turnarounds rather than long single-plant runs to get the most out of the four-pot layout.
Scaling up
Add further Multi-Pot modules off the same reservoir if you need more than four plants, rather than trying to retrofit extra pots onto one module.
Technical specifications
- System type: Gravity-fed, 4-pot module
- Pot size: 4 x 16 Litre
- Valve: Single MegaValve, 10mm inlet, feeds all 4 pots
- Footprint: Approx. 80cm x 80cm
- Power required: None, fully gravity fed
- Best suited to: Shorter plant cycle lengths
- Expandable: Yes, additional modules can share one reservoir
- Manufactured: United Kingdom
Who this is for
- Growers running four plants who want a single feed point rather than four separate valves
- Growers on shorter cycle crops who turn plants over more often than a single long-run grow
- Anyone already running a single Mega Pot module who wants to scale up to a multi-plant bank
- Growers who want gravity-fed simplicity across multiple plants without extra pumps or timers
If you only need to water one plant, the single Mega Pot Grow System is the simpler starting point.
Our take
Running four pots off one valve instead of four is the real advantage here, less hardware, less to maintain, and the same reliable gravity-fed principle as the single-pot version.
Worth picking up if you want equipment you can rely on across a full four-plant bank.
