The NK-150-1.2 Duct Heater (150mm - 1200W) is the ultimate tool to keep your indoor crop at the perfect temperature without sacrificing a single centimeter of growing space. This powerful device integrates directly into your ventilation system, heating the intake air before it reaches your plants, ensuring a stable climate even on the coldest winter nights.
We've all been there: winter arrives, temperatures drop, and you panic. You end up putting a bulky oil radiator or a fan heater inside the grow tent. Suddenly, you have no room to move, you're tripping over extension cords, and you've had to sacrifice space where two or three more pots could fit. Your grow space turns into an obstacle course.
This excess gear creates chaos. The radiator burns the leaves of the plants closest to it while the ones in the corner are freezing. You spend the day adjusting thermostats, worrying about humidity dropping too low because of the dry heat, and stressing about the lack of space. It's inefficient, dangerous, and honestly, a headache you don't need.
The solution is to stop heating the space from the inside and start heating the air before it enters. With the NK-150-1.2, you remove the heater from the floor and integrate it into the ducting. It allows you to reduce gear, simplify your setup, and ensure that every cubic meter of air entering your crop is already at the perfect temperature.
This device is a masterclass in functionality. By installing the heater inline with your Air Extraction System (specifically the intake), you turn a simple ventilation tube into a sophisticated climate control system. You no longer need a separate device taking up footprint in your tent.
The NK-150-1.2 works with a 1200W heating element that warms the air as it passes through. This means the heat is distributed evenly by your air circulation fans, eliminating those dangerous hot spots caused by traditional radiators. It groups ventilation and heating into a single, streamlined channel, freeing up the floor for what really matters: your plants.
Once you install this duct heater, you'll realize how much junk you were tolerating. Here is what you can say goodbye to:
Simplifying your setup with the NK-150-1.2 is easier than it looks. Follow these steps to clean up your crop:
Switching to duct heating isn't just about saving space; it improves the quality of life for you and your plants:
For most standard grow tents (up to 1.2m x 1.2m or even slightly larger), 1200W is plenty to raise the temperature of the intake air significantly. It is designed to temper the cold air coming from outside, not necessarily to bake a room from scratch.
No, never. The duct heater must always be used in conjunction with Air fans or inline fans. There must be airflow passing through the heating elements to prevent overheating and ensure the heat is pushed into the tent.
The ideal placement is at the end of the intake duct, just before the air enters the grow room, but always after the fan. This ensures the fan is pushing air through the heater.
I remember the days when I used to trip over oil radiators inside my 1.20m tent. I lost space for at least two good-sized pots, and the plants closest to the radiator always suffered from heat stress. Switching to the NK duct heater was a game-changer for my setup. It allowed me to clear the floor completely.
My advice? Don't just plug it in and leave it running 24/7. Pair it with a simple thermostat. This way, you only use electricity when the night gets truly cold. It’s the most efficient way to grow in winter without complicating your life with extra gadgets inside the tent. Once you go inline, you never go back to floor heaters.
