The model tested was not that much dosh mate! methinks your thinking about the top model. This one is very nicely priced. about right for a LED its size and power.
But anyway......dosh is not what I wanted to discuss...its not about comparing prices etc... its about seeing what it could do.
The point of my test was to see if a lower powered LED could do a good job, @ 90 W total consumption its pretty impressive and that seedling had a cold few weeks start aswell.
Show me a 90W LED (one that draws 90~W of power to drive its LED's, Fans, etc.., not output) that can produce 118 grams from a grow that was stunted from the start cos of the cold and ill eat my LED.
Plus perfect for hot climates, as it doesn't even emit hot exhaust like most LEDs do & completely silent, not quiet, silent. no noise at all.
No speculations, just proof.
All LEDs do work nowadays, more or less imo but a huge part of it is of course, the growers skill.
At the end of the day, its all about the growing and how your happy with it, a bad workman always blames his tools anyway lol.
