Ok.. thanx kindly for that info!
Now, I've seen a lot of comments, positive and negative, regarding the "blurple" light sets. Are they really no good? Or are they something that should be used in conjunction with the full spectrum white light? Or only any good on expensive set ups?
It just comes down to how much light you use. You need more with a cheaper LED than with a good one. But if you use enough light then you will get good buds (as long as you do everything else right)
The other issue is reliability , when they make cheap lights they use cheap parts and run them hard to get the most light from those parts, plus cheap means lower quality control, so could be they don't last long, cheap drivers burn out quicker , cheap diodes may burn out leaving you with a light that only lights up half the unit.
Blurples have a bad rep due to the misleading figures they use to advertise too, they may call a light 1200w to make it sound good, then say its equal to a 400w hps and then say only draws 132w power, so they mislead the consumer to buy something not up to the task and then disappointing results follow, specifically in flower.
That same light that sounds so good might cost $100, which again sounds like a good deal but when you need 3 of them to light a 2x4 space and you've ended up spending $300 and could of bought a good light to start with which would of cost less, used less power overall, been quieter and lasted a long time.
Seen some good grows using blurples , mostly by people who knew what they were buying from the start and knew how to utilise what they had and probably got a bit lucky that the light wasn't faulty.
