Full description
Mammoth Pro+ HC – 225 cm High Grow Tent for Bar LEDs
The Pro+ HC is the Pro+ with an extra 25 cm in height. Those 225 cm make the difference between hanging the LED where it fits or having to sacrifice plant growth space: there is room for the light, pulleys, carbon filter, and still plenty of space above the grow.
This is the ideal range for growing with high-power bar LEDs, for tall varieties, and for those working with large pots or raised tables that lose useful height at the bottom.
Key Features
- 225 cm height in all five sizes: 25 cm taller than a standard 200 cm tent.
- Interior lining made of 600D Mylar with 95% reflectivity.
- 22 mm steel tube frame, thicker than the standard Pro+.
- Multiple ventilation ports and cable ports distributed throughout the tent.
- Removable bottom for easy cleaning and to prevent heat buildup.

1. Check that you have at least 235 cm of clear height in the room before purchasing.
2. Assemble the 22 mm steel frame on level ground with the back panel in place.
3. Fit the canvas cover, starting with the roof, then close the sides and front door.
4. Hang the bar LED light using the full height: leave enough slack to raise and lower it.

Frequently asked questions
-
The Pro+ HC is the Pro+ with 25 cm more height: 225 cm in every size. Its frame is also made from 22 mm steel tubing, thicker than the standard Pro+. Those extra centimetres make the difference between hanging your LED where it belongs and sacrificing plant height.
-
This is the range to go for if you grow under high-power LED bar fixtures or with tall-growing varieties. It also suits anyone using large pots or raised benches who loses usable height at the bottom. If height is your limiting factor, this is your tent.
-
There are five versions, all 225 cm tall: 120 x 120 (1.44 m²), 240 x 120 (2.88 m²), 240 x 240 (5.76 m²), 300 x 150 (4.50 m²) and 300 x 300 cm (9.00 m²). Approximate weights range from 21.2 kg to 69.8 kg. Choose according to the area you want to cover with your lighting setup.
-
The inner fabric is 600D Mylar with 95 % reflectivity. The material is 100 % lightproof and non-toxic, with PP polymer corners. That way you make use of almost all the light your fixture puts out.
-
The floor tray is removable, which makes cleaning far easier and helps prevent heat building up. You can take it out between harvests and have the tent ready for the next cycle. Regular maintenance extends the life of the fabric.
-
The tent has multiple ventilation inlets and outlets and cable ports spread across different points, so you can adapt the setup to your room. Mammoth does not publish the exact number or diameter of these ports, nor does it specify a drip tray, inspection window or rear door. We only publish data confirmed by the manufacturer.
