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.

Ac infinity 3x3 tent kit.

Very happy with the product. Would definitely recommend over the cheap tents you get what you pay for. Just set it up and about to start germinating my seeds.
