Greenhouse Vaporizer by Grow1 - Sulfur Burner for 1,000 sq ft, 140°C (205011)

Grow1 Greenhouse Vaporizer for Sulfur Treatments

The Grow1 205011 is a compact heater built to vaporize elemental sulfur inside a closed grow space. It brings the sulfur to 140°C (284°F), the point where it vaporizes rather than catching fire. The vapor drifts through the room and settles as a fine film on leaves, stems and surfaces. Growers use that film to keep powdery mildew from getting a foothold during veg. One unit covers roughly 1,000 sq ft, so a larger greenhouse or several rooms take several units. The body measures 6 x 6 x 8.5 in and weighs 1.6 lb, small enough to hang or set wherever the air is still. Grow1 limits treatments to the vegetative stage, before flowers set. Each run happens at night, with fans and ventilation turned off so the vapor stays put. Nobody stays in the room while it runs, and a timer handles the on and off. That routine makes it a scheduled, hands-off part of an IPM plan rather than a reaction to an outbreak. Because the dose is a vapor, it reaches the undersides of leaves and the tight spots a sprayer misses.

Running a Sulfur Burner Safely on a Timer

Plug the unit into a timer before the first run, so you never stand next to it while it heats. Set the timer to start after lights-out and to stop well before anyone returns in the morning. Shut down every fan, exhaust and intake on the same schedule, or the vapor leaves the room before it settles. Load the unit with elemental sulfur and place it centrally, away from anything that could be scorched. Keep it clear of foliage, trellis netting and anything else that can catch heat. Run treatments only while plants are in veg, and stop before the flowering stage begins. Air the room out thoroughly before anyone goes back in after a cycle. Check the instructions on the sulfur you use for its own rates and re-entry interval. For more than one room, give each enclosed space its own unit sized to its square footage. A regular schedule through veg tends to work better than a single heavy treatment once mildew shows up. It works alongside good airflow, sensible humidity and clean intake air rather than replacing them.

Key Features
