None... And I have no idea. My first LED... Hell, on the way to Portland, I met a guy in a parking lot to buy another TekLight... But the thing was broken. Still was fun... Felt like the "old days".
I just ordered that light and tent to make some seeds separate from the other plants... But since it's here, I'll use it to quarantine these plants... I was probably just going to throw these in the "greenhouse" otherwise.
We got to get you going on a proper LED Bud, and there's no turning back once you get your toes wet. I'm pretty sure that ones going to do well for you, but it's only about half way there. It's a good one, don't get me wrong, but the REALLY good ones, are going to have samsung LED's (anytype are great, as long as they begin with an LM301 bulb) The H is best, but anything in the LM301 generation is going to be excellent. The other key is this, spreading the lights out, instead of having them bunched up on a panel, like yours are. Don't get me wrong, panels are very effective, I've got 2 of them I use, and I've had another 20 older ones that I've gone though over the years, but the newer 4x4 sized light, that have the bulbs spread out (Personally I didn't think the would be effective) but I was WRONG, the are the most effective, and it's because they throw out light from different perspectives, and you get layers of shadowing, and way, way better canopy penetration.
Welcome into the new way of doing things, your going to really dig your lights.
This one cost me around $900 with taxes, but it was like a $1300 fixture, so I pulled the trigger. The
Gavita Pro 1700e have come down some, that's the one you should be eying. It's the pinnacle of LED tech right now, unless something's displaced it recently...
This light has LM301H 3000's & Osram 660's, but I think there's some LM301B's in there too @5000. I think the very best lights have the LM301H@4000.
Gavita doesn't seem to share information on it's light ratio's, I think it's a trade secret, of sorts.
The other thing you want to be eying, is a few of those agromax t5 UVB's, just for the flowering rooms. Those are a cheaper leap, and I think they would probably give you more bang for your buck, and give more immediate results than changing all over to LED's. Simply put, those would add resin weight to your end product, and only cost you 65 watts each. I would get one or two of them, and do a side by side, I think you might be impressed.
