@ViparSpectra, I was reading your charts on the ks5000, are you sure these numbers are correct? Its claiming the ks5000 will replace a 1k hid, I'm finding this hard pressed with just drawing 500w.. I have other lights that are 450w and their ppfd is closer to a 600w then a 1k hid. I'm...

Next up I'm going to try to talk he old lady into letting me get some wall fans for each section, we will see how she reacts to that..

To help prevent light spills from each light, I decided to section off the lights.

Soil web is already starting to form! I have a feeling this is going to be a good batch of soil.. @VIVOSUN Official @Phlizon LED Grow Light

JK/ they are missing out, I dont have a vipar, but my buddy does and Ive seen the results of it, "its one of the reasons I switched to led's".

I shoved them all in my basement and locked the door, I got tired of seeing everyone else win lol :)

All systems are a go.. @VIVOSUN Official @Phlizon LED Grow Light I have started germinating seeds, I'm old so the only method I use is paper towel method, been using this method for many years and it hasn't failed me yet. Things will start to pick up from here on.. HVAC crew will be in next...

I'll come trick or treat for that! Lol

After shipping it was over 100 bux, bout the most I could spend on a par meter

It's an app that came with the par meter, called Tuya Smart.. I got the FH-100 Par Meter.

Now I can test better, instead of saying "its bright", I can just show the data :)

I got a new toy!

Here is another observation… The PL4500 runs the hottest “enough so I let them know about it”, you can not touch this light when it’s been running… The VS4300 runs very cool, hardly much heat and the sf4000 does get warm but you can hold your hand on it, the pl4500 you can not, it will hurt if...

Still too early to tell but I figured par readings would be a good start

So far from what I'm seeing is the sf400 is one bright ass light, it stays with the 600w at all ranges, but the vs4300 has better spread and is more consistent, it drops off the least.. The PL4500 is still putting out good numbers for its price range, I was surprised.. The 18in mark is its...

I can see how the 400s can compare to the 600w after I took these readings,.. the hps is good for up close, after that it really drops off badly

I've already got my ideas of what is what based off test results, these par meters are amazing

But yes, I will be getting co2

No plants in room yet, just testing and they wont be ran full blast like this when plants are under them

Here are the results at 18in mark. @Spiderfarmerled SF4000, 18in, center. @VIVOSUN Official VS4300, 18in, center. Showed the least drop. @Phlizon LED Grow Light PL4500, 18in, center, this seems to be sweet spot for this light. 600w hps, 18in, center. This is where they catch up..
