This 1500W electric greenhouse heater is built to cut through damp air and poor circulation that can slow plant growth, running in heating mode for fast, even warmth or fan-only mode for ventilation. Two heat settings let you choose the right output for the day, and the head tilts up to 15 degrees so warm air reaches the plants or work area rather than just the ceiling. Overheat protection shuts the unit off automatically, and the high-hardness cold-rolled steel housing resists warping and cracking with regular use. At only 3.7 pounds, it's the lighter, easy-to-carry version of this heater, with a portable handle and a stable, grippy base that make it simple to move between a grow tent, small greenhouse, flower room, or home office. It's a straightforward, portable option for keeping a controlled growing environment comfortable through the colder months.
