Nice unit

The fan seems well designed and built. The design allowed installation in hard duct work w/o needing a flex section. Not necessary in most installations, but important in mine. Whisper quiet at low speeds. Pleased to discover that the speed control returned to the last selected speed after a power failure.

HLG 350

So far just starting a run, but all is well. I’m playing with the light height and intensity as the run progresses. Easy setup no issues a solid light. I’ve owned dozens of grow lights over decades of growing HGL 350 appears to be on par with the others I’ve owned and still do.

Cheap and dangerous

Dulytek presses are outright dangerous, missing crucial pieces can lead to serious injury. I had missing washers on top of cage springs that launched the nuts and clips like bullets.
