Description

Complete Indoor Hydroponic Growing System. Sorted.

More Space. More Canopy. More Growing Potential.

Green Stack VHX™ centralises four plants into one vertical footprint, combining hybrid hydroponics, automated irrigation and 360° canopy training. The result: more productive space, easier maintenance and greater growing potential from every square metre.

Grow More Without a Bigger Grow Room

Centralise the Roots. Expand the Canopy. Traditional pots spread root zones across valuable floor space. VHX provides 110L of combined root-zone capacity within one compact platform, freeing more surrounding space for canopy development. More of your grow room becomes productive growing space.

More Light. More Branches. More Flowers.

Build a 360° Canopy Around the Light The 360° Canopy Training System™ encourages branches outward through three support levels, creating a vertical SCROG-style canopy around the central light source. This improves light exposure and creates more room for productive branching and flowering.

4 phases of growth vhx indoor hydroponic hybrid growing system australia

The Best of Two Hydroponic Methods

Water From Above. Oxygen From Below. VHX combines top-feed recirculating hydroponics with Deep Water Culture (DWC). Nutrient solution circulates through the coco/perlite root zone while an air pump oxygenates the 80L reservoir below. Mature roots can then extend into the oxygen-rich reservoir. Consistent moisture, nutrition and oxygen in one integrated system.

Give Your Roots Room to Grow

110L Centralised Root System™ VHX provides 110L of coco/perlite root-zone capacity, giving four large plants substantial room to develop within one footprint. As roots mature, they can extend toward the oxygenated DWC reservoir below. One central root zone. Four plants. One productive footprint.

Less Watering. Less Clutter. More Control.

Four Plants. One Integrated System. Instead of separate pots, trays and watering equipment, VHX combines one reservoir, one irrigation system and one oxygenated nutrient supply. Programmable irrigation maintains consistent moisture while the 80L reservoir reduces frequent manual watering. Less time watering. More time growing.

Move Your Entire Garden

Plants, Roots, Reservoir & Canopy — Together. The reservoir, planters and canopy frame sit on one heavy-duty mobile platform. Move or rotate the entire planted system for easier training, inspection, cleaning and maintenance. 360° growing deserves 360° access.

Designed to Make Indoor Growing Simpler

VHX integrates root space, irrigation, oxygenation, canopy training and mobility into one purpose-built platform. Choose VHX System for use with your existing indoor equipment, or VHX System Plus for the complete tent, lighting, ventilation and filtration package.

Hyrdro axis ventilation fan

Hydro Axis 150mm Inline Axial Fan + Ducting

Fresh Air in – Warm Air out.  Extraction works best as part of a complete airflow system.

The 150mm Hydro Axis ball-bearing inline fan provides the VHX Plus package with dedicated air movement/intake, while matched 150mm ducting connects the ventilation and filtration equipment together.

Included

  • Hydro Axis 150mm / 6-inch inline axial fan
  • Ball-bearing fan construction
  • 150mm flexible ducting
  • Duct clamps and connection hardware
  • Compatible with the 150mm extraction/filtration system

This creates a simple airflow pathway:

Fresh air in → across the growing environment → warm/humid air through carbon filtration → extracted out.

Green Stack VHX Indoor Growing System - FAQ

This simple form of hydroponics solves under & over watering.   Modular stacking planters are filled with coco coir & perlite, than connected vertically through a center pole connected to an electric or solar pump which sits inside a 60 litre reservoir.    

Nutrient is added to the water reservoir which is automaticaly pumped to the top layer and filtered down through each layer (instructions provided).   Because the coco coir is so porous you basically cannot over water your garden (assuming it’s getting good sun).

The system is designed for 4 plants with large root systems.   With 30L of growing medium above and 80L below, 4 large plants or 8 medium size plants is ideal for a system of this size. 

VHX System includes the complete hydroponic growing platform. VHX System Plus adds the 1.2 × 1.2 × 2m grow tent, premium 645W LED light, extraction fan, carbon filter, intake fan and ducting.

A submersible pump delivers nutrient solution through the coco/perlite planters before it returns to the 80L reservoir. An air pump oxygenates the reservoir, allowing mature roots to also extend into the DWC solution below.

Instead of spreading four separate pots across the grow room, VHX combines around 110L of growing-medium capacity into one compact vertical platform, giving large plants substantial root space while reducing floor-space use.

Three integrated support rings allow branches to be trained outward using plant ties or netting, creating a vertical SCROG-style canopy around the system rather than allowing plants to grow only upward.

Training branches outward creates a wider, more open canopy with improved light exposure and airflow, while making better use of the vertical and surrounding grow space.

VHX uses approximately 60% coco coir and 40% perlite, providing excellent moisture retention, drainage and root-zone aeration.  

Coco/perlite is highly free-draining and much more resistant to waterlogging than traditional soil. Correct irrigation timing is still important, but the blend is very forgiving in a recirculating hydroponic system.

The VHX System includes a large 80L reservoir, helping provide more stable nutrient concentrations and reducing the frequency of topping up compared with smaller reservoirs.

The Smart Farm comes with quality hydroponic nutrient that is in 2 parts (A & B).   This nutrient is designed to grow various plants in all stages of growth.   So you don’t need to mess around with different ‘grow’ vs ‘bloom’ blends and complicated additives like some other systems.  

To use, simply fill the 1.25 litre bottles that come with the system with water, shake well, then once dissolved, add it to the reservoir at a rate of 5ml nutrient per litre of water for both parts A & B.   As the reservoir is 60 litres, you therefore can add 300ml of each.  This will last 2 weeks before you need to replace it in the tank.   
*Note: Less is more with this stuff as it’s powerful!   So half this dosage for seedlings

See the below video for how to mix and use the nutrients

The air pump and air stone increase dissolved oxygen in the reservoir, supporting healthy roots and enabling the Deep Water Culture component of the VHX system.

Yes. The reservoir, planters, plants and canopy-support structure sit on heavy-duty lockable castors, allowing the entire planted garden to be repositioned as one unit. 

Mobility makes it easier to access plants for training, inspection and maintenance, as well as cleaning around the grow area without dismantling the canopy  

No. If you already have suitable lighting and an indoor growing environment, choose VHX System. If you want a complete matched indoor setup, choose VHX System Plus.

Yes. The same system supports plants through their growth cycle, with the integrated canopy structure allowing progressive training as plants move from vegetative growth into a larger flowering canopy.

VHX is designed around four substantial plants with large centralised root capacity, allowing growers to concentrate their available space into a manageable number of plants while developing a broad trained canopy.  

Yes. Experienced growers can adjust irrigation schedules, nutrient strength, canopy training and environmental settings while taking advantage of familiar techniques including DWC, coco growing, LST, SCROG and recirculating hydroponics.
