I assume that you started them flowering before you joined here and that you've been catching up since there are 5 weeks worth of growth in less than 3 weeks. Are you caught up to present day now?
You said that you grow 3 strains but the pictures only look like one sativa strain. Can you fill us in so we know which is which? How do you stagger everything since the 3 strains have different flower times? Do you put some in early so they all finish at the same time or do you throw them all in at the same time, rotate them around and harvest as they become ready? Maybe you have separate flower tents for each strain?
OK, so now we know that you grew 3 strains and got about 3oz each from 12 plants under 2kw, now we can do the math on the old setup.
12x3oz = 36oz = 2.25# = 1044 grams / 2kw = .52g/w
.5g/w isn't bad for newer growers but you've been doing it for 20 years so I'm trying to figure out why the old HID yield is so low. Any ideas? My first thought was maybe the strains aren't big yielders but I doubt that's it.
I'm also confused about the early finish compared to HID. A day or two I could wrap my head around but two weeks early? On a 8, 10 or a 12 week strain?
I'm also not sure how the flowers could be so much more dense than HID when all of our journals show smaller/less dense flowers at the end but time will tell...
To me less water and nutrients makes sense but maybe the spectra of LED can help them metabolize more efficiently. Are you feeding the same ppm as you did under HID? You might adjust your formula if you think it'll help. As long as they're not showing signs of nutrient toxicity then more food MIGHT equal more yield or it might equal burnt leaves.
If they're healthy and happy, that's the most important thing...

I'm not sure how to approach this one; normally I would research a new light that I haven't heard of before and give my opinion on what I find but this one is so bad, with so many red flags, I'm not sure that you want to hear it. For your sake, I hope the light is better than the website. I certainly wouldn't pay 1000.00 each on one of those so I hope you got a better deal at your hydro shop too.

Like I said, I did a vast amount of research on all LED lights available on the market. Being a guy who has been doing this for 20 years I do not go into things blindly, nor do I spend $2000 on a whim. Research on the internet turns up next to nothing on these lights (like many other brands) but when you look at the actual specs this one came out on top. Plus there is a 90 day warranty and I know the man that runs the shop I bought them from so if, after 12 weeks I am not happy I can always return them and go back to my HID lighting. Currently, the results are phenomenal though.

From everything I have read, for veg, we want 450nm.. which is a blue color and we want 660nm for flowering. This purple is more like 420 nm. What's with that? Is this because there aren't any bright blues or red LEDs near these wavelengths? I see this in most of the pictures of LED grow lights, orange-red and purple LEDs. What am I missing![]()
Thanks in advance!
