I would go with UV-A over UV-B personally. If your running UV-B i would try to run it in short bursts. It can be very powerful.

I was giving only blue. Then only uvb at transition up until the end of mid bloom, which is just red and blue on at the same time.. unless I'm mistaken I thought uvb was a type of ultra violet that my led made by combining both the red and blue bloom and veg lights and this lowering the spectrum to the 0-400 of a uvb I assume. Now for the start of late bloom I flicked it on just red and plan to use that the next week or two until last 3-7 days before harvest where I plan to go back to just only blue veg light to increase resin and terpenes.by up to 50%

Why not just give them a balanced spectrum?
And not sure if your talking yellow light with blue added, and then right now you have yellow with red added. If your actually using 100% red somehow be careful with bleaching the tops in flower, if its just added red then dont worry about it.

For efficiency and overall growth balanced is best but I'm trying to do the individual light spectrums to achieve better quality.. nothing wrong with a balanced spectrum. I am trying more advanced tests to increase quality based on research. I know growth in structure may lack without the blue and I wish I had a 2nd led but I only have the one and I believe the deep red would be best at late flowering for sure up until the last week before trying out this blue light last few days thing. I also have no FR so that will have to wait until the next grow. But I believe far red is used for the 10 mins before lights go on and 10 min after they go off. Also heard it helps a little but not a major change or difference so my plants will be fine.

that's not uv-b. that's purple.
i'd run red and blue on all the time from start to finish.

They are looking a little fluffy. Was trying to red light to dense them up.

Strains that were a big dissapointment.
I thought i'd start a thread about what strains didn't live up to the hype, i rather just avoid the seed bank battle's (but thats up to you). i'm interested in what really you// had high hopes for, & the end result was just average at best or below.. i got alot of experience & can shed knowledge...

It probably is a blurple light. I plan on getting % setting of spectrum channel controller paired with a led for better environment control on the next grow. I didn't have much cash so I bought the 1000w for 79$

So run the purple with both them on ? If I had a 2nd light I would do one red one blue instead of a single light mixture of them for purple. So you still want me to run purple ? Even though they are a little fluffy? Will they dense up after late flowering more ? It seems they just finished the grow stretch. I was thinking since I only got the one light to just do red. I wish I could do blue with it. Are you sure to put it back on purple until the end ? Also what's ur opinion of blue lighting for last few days for increase terpene levels and resin?

That light is severely underpowered, run both full blast. Switching from one colour to the other is going to do absolutely nothing to dense up your flowers.

I quoted his post with his light and this one from 2008 popped up. Weird dude lol

What about it is underpoweful ? I did make sure to get the 1000watts. I'm sure it's enough to cover the one grow tent ? How many watts for a tent in your opinion? 2k? I heard 55 watts per square foot is good?

Read the last line in the description. ...actual power 145watt.

Your light is 185w. Meaning it’s severely underpowered. Not sure what else to tell you.
Of that 185w it’s probably stealing 30-50w to run the fans, so you’re looking at a120w light now

Why did they advertise 1000W in the title? So actual power is what I should be looking at. Damn light business thieves..also I read just now jack Herer is on the fluffy side for it's strain genetics so I guess i have to expect the harvest buds to not be too dense based on genes, it's out of my control.

I just turned both on so back to purple it is. Should I put it on blue light only last few days for more terpenes? My next lights with a controller will cost more and have a power unit for them separated outside the tent to help keep temps down, I'm sure the watts on them will be advertised better. I will make sure to be careful still prior to purchasing thanks again for light advice!
