Exactly. I didn’t realize the far red(eod) light was plugged in. Qb were on 24/7 eod 6minutes for 12days. On one end of the room the plant was completely exposed to the light on the other it was shielded. In between a little less. I’m pretty sure the long one has SAS. Crazy stretch. image|375x500

Here’s this week. Same 2 strains mku and blue dream.

Continuing the discussion from Let's talk DIY lights:

Hi. I’m just finishing my second grow. 4x4 tent, soil, Viparspectra Par1200 dimmable… I really want to upgrade my light. I’m really considering the HGL VR 550 rspec. I know that the 600 kit is cheaper, but I like the convenience of the plug and play, and the price will not be a factor in my decision. would this light be too much in my tent? Or would the 600 kit be better.? Thank. Also my next grow, I’m moving to ProMix if that’s a factor.

I think your best bet there would be to go with two 260xl kits. It’s better coverage and more flexibility than either of options you listed, and closer to 600 kit in price. If you want plug and play you can pay a little extra to have growerslights assemble and test.

Thanks for the input! I’m going to look at 260’s.

And everyone is always after the blue for growth…

@dbrn32 I’m getting weary of waiting for the plc light strips. It seems they’re perpetually sold out.

What are your thoughts on the 757 optisolis on cutter? A flowering light build using the 2700k 97cri strips. With 97 cri would they be a better light for flowering than the plc strips or hlg r spec boards?

@Drinkslinger try the 3030 j strips from cutter. 90CRI.

The ones cutter fabs with Cree 3030s? They’re certainly cheaper, but I’d think 97cri of the 757 might edge out the 90 Cri on the cutter strips.

I’m looking to build a really really good flowering light. Cost is always a concern, but not a deal breaker. I’m not afraid to pay for something that will flower better than my current plc strip build.

I’m tempted again by the fluence lights, but believe that I can build the same or better for less money.

The difference between 90 and 97 CRI is negligible. And at quite a bit of cost difference it wouldn’t bother me a bit.
The 3030 strips seems to work great for flowering for me. :wink: @Drinkslinger

Anyone else watch sickids video? If not, you can just skip to around 18:30 to see relevant cannabis info. Btw. That far par sensor is $500-$600. Ouch.

The takeaway is blue isn’t so important, UVA is, red and far red are, but only in the proper ratio at the proper time. Hence hocking the apogee far par sensor.

If you’re chasing light spectrum more than light output, they are good choice. I don’t really know that you’re going to see a monumental difference for the cost, if any. If you’re looking at getting photons into your space those 3030j strips are a really good choice. The 3000k 90cri is going to give you more blue, 660, and 720 than a 3000k qb, and they are cheap enough to drive soft and make up for lower efficacy of the 90cri phosphor.

But, according to that video… blue is a non starter.

I don’t think photons are what I’m after. I think spectrum might be more important. But what do I know, I’m just a pot smoker.

How true that is. I’m pretty picky. I get a lot of shit for packing bowls, taking 2 hits, and knocking it out.

I watched 1 min from the middle of that video, and I drew 1 conclusion. You have to be able differentiate between height and development, can’t just say growth. Go find pictures of people trying to grow with incandescent bulbs. Those bulbs have more far red and ir than any other type of lighting in terms of spectral distribution, and they grow like shit.

I’m not discounting the need for broad light distribution, because loads of blue light and little red light doesn’t exactly grow well either. But you want to be reasonable with expectations on both accounts.

Personally, I thought that video was 17 minutes of yawn 2 minutes of good info, and 1 minute of shilling…

Also they admitted to the flaw in their research.
