Grow cabinets are sealed, insulated boxes that hold a complete indoor growing environment in a small footprint. Hydroponics UK stocks the full G-Tools Bonanza range, from the 0.35m² empty shell at £785 to the complete 3-in-1 Bonanza system at £899. The 0.35m² size suits 1 to 5 plants; the 1m² size holds 2 to 10. Clima models add a carbon filter, extraction and remote control. Aluminium frames with PVC/XPS sandwich panels insulate heat, sound and light.

A grow cabinet gives you a controlled growing space without building a custom room. The aluminium frame and PVC/XPS sandwich panels insulate against heat and noise. The panels also reflect light back onto your plants and block light from escaping. G-Tools build the Bonanza range in two footprints. The 0.35m² size is fridge-sized and holds 1 to 5 plants. The 1m² size is a wardrobe-sized cabinet for 2 to 10 plants.
Decide first how much you want supplied. An empty shell is the cheapest entry point and lets you fit your own fan, filter and light. A Clima model arrives with extraction, a carbon filter and a remote control box, so you only add a lamp. The complete 3-in-1 system layers automated irrigation on top. Match the footprint to your plant count and the spec level to how hands-on you want to be.
The four options below cover the main routes into a Bonanza cabinet. They run from a bare shell you kit out yourself to a fully automated growing environment. The table sets each against its best use and a headline spec.
| Model | Type | Best for | Key spec | Price |
|---|---|---|---|---|
| Bonanza 0.35m² Empty Shell | Bare cabinet | Growers fitting their own kit | 176 × 61 × 61cm, 1 to 5 plants | £785 |
| Bonanza Clima Grow Box 0.35m² | Climate-controlled box | Just adding a light | Carbon filter, 45dB, up to 250W | £1,095 |
| Nursery 0.35 Multi-Layer Cabinet | Multi-layer propagator | Seedlings and microgreens | 3 floors, 0.75m², 6 LED panels | £2,065 |
| 3-in-1 Grow System Bonanza 1m² (Matt's Pick) | Complete system | A turnkey 1m² setup | 3 irrigation modes, 36L tank, 10 plants | £899 |
Best for: a turnkey 1m² cabinet for up to 10 plants
Why we rate it: one system runs drip, ebb and flow, or deep water culture. You trial all three before settling. The 36-litre tank and dual air pumps mean less daily fuss.
Price: £899
Size the cabinet by plant count and final canopy height. A 0.35m² box at 176cm tall suits 1 to 5 short, trained plants. The 1m² cabinet at 176 × 118 × 78cm holds 2 to 10. Both stand at fridge or wardrobe height, so check the ceiling and the doorway you carry it through. Sliding doors on the 1m² need no swing clearance, which helps in a tight corner or loft.
Heat is the main thing to manage in a sealed cabinet. The 0.35m² Clima extraction is rated for lights up to 250W; the 1m² Clima handles up to 600W. Keep your lamp under that ceiling and the fan copes easily. Add a grow light sized to the footprint. Then train plants low with topping or LST to fit the fixed interior. If you want hands-off feeding, the 3-in-1 irrigation system removes the daily watering routine.
We sell a lot of empty shells to growers who already own a fan and light. It is the cheapest way in. That said, the Clima box is the one we recommend most often. Getting the carbon filter, silencer and extractor matched and balanced yourself is fiddly. A saturated or undersized filter is the usual reason a grow smells. Buy the extraction sorted from the start and you remove the most common headache in one go.

A cabinet has rigid insulated panels; a tent is fabric over a frame. The Bonanza shell insulates heat, blocks sound and light, and locks shut. A tent is lighter and cheaper but offers less insulation and no security.
The 0.35m² size holds 1 to 5 plants; the 1m² size holds 2 to 10. Final numbers depend on pot size and training. Topped, low-trained plants let you fit more in a fixed-height cabinet.
An empty shell has no fan, filter or light; a Clima arrives with extraction and a carbon filter. The Clima box adds a fan, PK carbon filter, silencer and remote control box. You supply only the lamp.
No, all Bonanza cabinets are sold without a lamp. Choose an LED sized to the footprint from our grow lights range. Keep wattage within the Clima extraction limit of 250W or 600W.
The Clima models measure 45dB at 1 metre with the doors closed. A built-in silencer keeps the extractor discreet. That is about as loud as a quiet office or a soft conversation.
Yes, the G-Tools 3-in-1 system runs drip, ebb and flow, or deep water culture. It includes a 36-litre tank, pumps and 10 net cups. It is built specifically for the Bonanza 1m² range.
Build a full grow room around your cabinet. Light it with the right grow lights. Set up feeding on ebb and flow trays. Manage heat with the correct ventilation and filters.
