But you have to think of all the people that touched your food / products from start! Then it went to your trunk then into your house.

Agree far red uv def. Has its uses. Seems like sombody would build a light like some aquarium lights have that changes spectrum throu out the day. We’re comming along with it but with all this tech it seams like it would already be done instead of using timers switches and dimmers on just a few...

Thanks so much for this. Good find!

I’m seeing what your saying now. Shrink back a lot!

I found something interesting you might like to see if you haven’t already! Here’s a link. Is a good read about far red, better at bottom. https://www.maximumyield.com/far-red-lighting-and-the-phytochromes/2/17443

Yea I can’t wait to see what you come up with! I didn’t mean blue by itself. Using small amounts of red Blue with far red at flowering. I have a light that has a few 660 and 450 per strip at 3500k then I have a qb light with ir uv on one side of tent with same but no blue. In between both lights...

Thanks for the info. Are you using Cree or Osram reds? Please let us know your findings.I think I’m going to see if I can have some strips made 3500k with 660 on a separate driver so I can dim and blast at flower. With all this spectrum hype all white seems rare. Also want to check up to 450nm...

Sweet! Looks familiar. I’m having up to 10 branches 8 to 14inches down from top. Making for a lot of small buds. Thanks for the pic Johiem. I lowered n down but probably to late. Jacks good for growth but will take some adjustments for flower I see.

That makes sense. Grown in water and buds being nice and hydrated they would have to lose that water. Do you think the jacks could be part of the crazy amount of branching. Or is this typical of dwc too. I know there’s a lot of factors it could be. But lights I’m using right now aren’t to heavy...

What’s the hydro shrink? What I’m seeing already! Shit ton of little sites. I could avoid a lot of this if I’d grown photo. Wouldn’t worie about lolipoping and stressing them out. I didn’t even top these autos..I have some regular cuttings going now. One thing is for sure there will only be 1...

So I built a 4 bucket rdwc that seems to be working great but my problem is plants are way more than expected. I also switched to jacks 321. I started in dwc till I got it all built and all was great till I put them in. Was like pow! Nothing like my short stalky little guys, they took of like no...

NP. Can’t find the other vid but this guy says he didn’t think it was from light with both on. Good info on start to finish with lm301H uv ir quantam boards and his final thoughts on harvest vid. Here’s a link. There’s 5 vids. Just watch for his captions. Super plant on YouTube. Here’s part...

There’s a guy on YouTube that has 480 kingbite or? That has both uv and ir built in and he used them both at same time in preflower and it started to herm on him. Here’s a good study on far red test if you Havnt seen it yet. Great info. https://www.heliospectra.com/blog/far-red-light-and-cannabis

It does sound like a lot! Your right about the percentage of added outside spectrums. That’s what I was saying about a chart or? A percentage table I guess would be a better word. Seems like apogee would say something about this. I guess everyone that owns these should do testing and log there...

Thanks Bonmac your correct. So Yes suppose to compensate for the wider band. And yes I’m going to use his soon as I can to see we’re they stand in normal range with no uv or ir and see how close they are. With the dual head being able to read both separate this shouldn’t be a problem. Probably...

Not really a chart but a guide that can go by for using multiple spectrums before 400 and after680. I asked the guy were I bought it is there a change when using far red and uv and he said yes it’s safe to say using the 395 and 730nm These wavelengths are adding 10 to 20% to the number so add 10...

Thanks, yours as well. Came today so I’ll be testing this weekend I’m sure.

Pretty much same here. I have a few boards different brand diodes with 365 on up and over 730nm and curiosity is killing the cat so to speak. There for led but curious how pure uv will show up on it. Just a lot of unknowns that hopefully these new sensors will help with.

Sweet. Congrats. Now we can sharpen or pencils and get to work and share data. I looked at the 610 first. There’s like a handful of the 600 models. What made you go for that one particularly? I know it’s 2021 model and is specific for 380 to 760nm instead of going further out. Any other reasons.

Thanks for stepping in Budman, Well a friend has the 500 and I use it from time to time so figured I’d get my own. So I pulled the trigger on the 626 also. The umols have to be increased with the extended range. Do you know if there’s a updated chart to compensate this? We have been going with...
